How to Research Keywords for Google AdWords: A Complete Google Ads Guide

Table Of Contents

Introduction

If you have ever wondered why some Google ads appear exactly when you search for something and others seem completely irrelevant, the answer lies in one crucial skill: keyword research. Keywords are the bridge between what a potential customer types into Google and the ads that show up in front of them. Getting this right can make the difference between a successful ad campaign that generates real business results and one that burns through your budget with nothing to show for it.

This guide is written for anyone who wants to understand how to research keywords for Google AdWords – from complete beginners who have never run an ad before, to small business owners looking to sharpen their skills. You do not need to be a marketing expert or data analyst to follow along. Everything is explained in plain, simple language with practical examples throughout.

By the time you finish reading this guide, you will understand what keyword research is, why it matters, how the Google Ads system works with keywords, and exactly how to find, evaluate, and organize the right keywords for your campaigns. Let us start from the very beginning.

1. What Are Keywords and Why Do They Matter in Google Ads?

1.1 Understanding Keywords in Simple Terms

A keyword, in the context of Google Ads, is a word or phrase that you choose to trigger your advertisement. When someone types that word or phrase into Google’s search bar, your ad has the potential to appear on the search results page.

For example, if you run a bakery in Chicago and you bid on the keyword “custom birthday cakes Chicago,” your ad can show up whenever someone searches for exactly that phrase. If someone searches “birthday party ideas” instead, your ad may not appear, because that keyword is too broad and doesn’t signal buying intent.

Keywords are essentially signals of intent. When someone searches for something on Google, they are telling you – and Google – what they want. Your job as an advertiser is to figure out which words and phrases your ideal customers are using, and make sure your ads show up for those terms.

1.2 Why Keyword Research Is the Foundation of Every Campaign

Think of your Google Ads campaign like building a house. Keyword research is the foundation. If the foundation is weak, everything built on top of it – your ad copy, your landing page, your budget – will underperform. No matter how great your ad looks, if it is showing up for the wrong searches, it will not convert viewers into customers.

Good keyword research helps you:

Reach the right people at the right moment – when they are actively looking for what you offer
Avoid wasting money on clicks from people who are not interested in buying
Understand how your audience thinks and what language they use
Set realistic budgets based on actual search volumes and competition
Build campaigns that grow and improve over time

Bad keyword research, on the other hand, leads to low click-through rates, poor quality scores, high costs per click, and ultimately, campaigns that fail to deliver results.

2. Understanding How Google Ads Uses Keywords

2.1 The Auction System Explained

Google Ads operates on a real-time auction system. Every time someone performs a search on Google, an auction takes place behind the scenes in a fraction of a second. Google looks at all the advertisers who have bid on keywords relevant to that search and determines which ads to show, and in what order.

The position of your ad is not determined by your bid alone. Google uses something called Ad Rank, which is a combination of your bid amount, your Quality Score, and the expected impact of your ad extensions. This means that even if a competitor bids more money than you, you can still outrank them if your ad is more relevant and useful to the searcher.

2.2 What Is Quality Score?

Quality Score is Google’s rating of how relevant and useful your keyword, ad, and landing page are to the person who sees your ad. It is scored on a scale of 1 to 10, with 10 being the best.

Quality Score is made up of three components:

Expected Click-Through Rate (CTR): How likely is your ad to get clicked when it is shown? If similar ads with the same keyword have been clicked often, your expected CTR will be higher.
Ad Relevance: How closely does your ad match the intent behind the keyword? An ad about “men’s running shoes” should not appear for someone searching “women’s ballet flats.”
Landing Page Experience: When someone clicks your ad, does the page they land on deliver what was promised? A fast, relevant, and helpful landing page improves your Quality Score.

💡 Key Insight
A higher Quality Score lowers your cost per click and improves your ad position. This is why proper keyword research – which ensures relevance at every step – directly saves you money.

2.3 Keyword Match Types: A Critical Concept

One of the most important things to understand about Google Ads keywords is that you do not just pick a word – you also choose how closely that word must match what someone searches for. This is called a keyword match type, and there are three main types:

Broad Match

Broad match is the most flexible match type. Your ad can show when someone searches for your keyword in any order, along with related terms and synonyms. For example, if your keyword is “running shoes,” your ad might show for “jogging sneakers,” “athletic footwear,” or even “sports shoes for training.”

Broad match reaches the widest audience, but it can also attract irrelevant traffic if you are not careful. It is best used with strong negative keyword lists and Smart Bidding strategies.

Phrase Match

With phrase match, your ad shows when someone searches for your keyword phrase in order, but other words can appear before or after it. If your keyword is “running shoes,” phrase match would trigger for “buy running shoes online” or “best running shoes for women” but not “shoes for running fast in a race.” Phrase match gives you more control than broad match while still reaching a reasonably wide audience.

Exact Match

Exact match is the most precise option. Your ad only shows when someone searches for your exact keyword or very close variants of it – like plurals or minor spelling variations. If your keyword is “[running shoes],” it would show for “running shoe” but not “best running shoes.”

Exact match gives you the most control and usually produces the highest conversion rates because the searcher’s intent is very clear. However, it reaches a smaller audience.

Match Type	Example Keyword	Could Trigger For	Best Used When
Broad Match	running shoes	jogging sneakers, athletic footwear	Testing new keywords, wide reach campaigns
Phrase Match	“running shoes”	buy running shoes online	Balanced reach and control
Exact Match	[running shoes]	running shoe (close variant only)	High-intent, conversion-focused campaigns

3. Types of Keywords You Should Know

3.1 Short-Tail vs. Long-Tail Keywords

One of the most useful distinctions in keyword research is between short-tail and long-tail keywords.

Short-Tail Keywords

Short-tail keywords are brief, broad phrases – usually one to two words. Examples include “shoes,” “insurance,” or “restaurants.” These keywords have enormous search volume, meaning thousands or even millions of people search for them every month. However, they are extremely competitive, expensive to bid on, and often attract people who are just browsing rather than ready to buy.

Long-Tail Keywords

Long-tail keywords are longer, more specific phrases – typically three or more words. Examples include “best waterproof running shoes for flat feet” or “affordable car insurance for new drivers in Texas.” These keywords have lower search volume individually, but they are much more targeted, less competitive, and much more likely to convert.

For most advertisers – especially those with limited budgets – long-tail keywords are the sweet spot. They allow you to reach people who know exactly what they want and are closer to making a decision.

💡 Why Long-Tail Keywords Win
A person searching for “shoes” could be looking for anything. A person searching for “women’s navy blue waterproof hiking boots size 8” knows exactly what they want and is probably ready to buy. Long-tail keywords target this second type of person.

3.2 Navigational, Informational, and Transactional Keywords

Another way to classify keywords is by the intent behind them. Understanding intent helps you match your ads to the right stage of the customer journey.

Navigational Keywords

These are searches where someone is looking for a specific website or brand. For example, “Nike official website” or “Amazon login.” These are most useful for brand protection campaigns – making sure your brand appears when people search for you by name.

Informational Keywords

Informational searches happen when someone wants to learn something. Examples include “how to tie running shoes” or “what is comprehensive car insurance.” People in this phase are not ready to buy yet. While informational keywords can build brand awareness, they typically have lower conversion rates for direct sales campaigns.

Transactional Keywords

Transactional keywords signal that someone is ready to take an action – usually to buy something. Words like “buy,” “order,” “get a quote,” “book,” and “download” often appear in these searches. Examples: “buy Nike running shoes online” or “get car insurance quote today.” These keywords are the gold standard for direct response advertising because the searcher’s intent is clearly commercial.

Intent Type	Example	Conversion Potential	Best For
Navigational	Nike official site	Medium (brand loyalty)	Brand protection campaigns
Informational	how to choose running shoes	Low to Medium	Awareness, retargeting
Transactional	buy Nike shoes online	High	Sales, lead generation

3.3 Branded vs. Non-Branded Keywords

Branded keywords include your company name or product names. Non-branded keywords are generic terms related to your industry. Both have their place in a well-rounded strategy. Branded keywords tend to be cheap and convert extremely well because people searching for your brand already know you. Non-branded keywords help you reach new customers who have never heard of you.

4. Step-by-Step: How to Research Keywords for Google AdWords

Now that you understand the fundamentals, let us walk through the actual process of finding the right keywords for your campaigns.

Step 1: Define Your Campaign Goal and Target Audience

Before you open any keyword tool, you need to be crystal clear about two things: what you want your campaign to achieve, and who your ideal customer is.

Ask yourself these questions:

What action do I want people to take? (Purchase, call, sign up, download)
Who is my ideal customer? (Age, location, interests, problems they are trying to solve)
What problem does my product or service solve?
What language does my target audience use when describing their problem or need?

For example, if you run a local plumbing company in Denver, your goal might be to get phone calls from homeowners with urgent plumbing problems. Your ideal customer is a Denver homeowner who needs fast, reliable help. They are likely searching for things like “emergency plumber Denver” or “burst pipe repair near me” rather than “plumbing history” or “how pipes work.”

Step 2: Brainstorm a Seed Keyword List

A seed keyword is a broad, foundational term that describes your product, service, or industry. You will use these seeds to generate a much larger list of keyword ideas.

To build your seed list, start by answering these questions:

What is your main product or service? (e.g., “plumbing services”)
What problems do you solve? (e.g., “leaking pipes,” “drain clogs,” “water heater repair”)
What categories or types of your product exist? (e.g., “residential plumbing,” “commercial plumbing,” “emergency plumbing”)
What location-based terms are relevant? (e.g., “Denver plumber,” “plumber near me”)

Do not overthink this step – just brainstorm freely and write down every word or phrase that comes to mind. You will refine the list later.

Step 3: Use Google Keyword Planner

Google Keyword Planner is the primary, free tool built directly into Google Ads for keyword research. It was designed specifically for advertisers and gives you real data from Google’s own search engine.

How to Access Google Keyword Planner

To use Keyword Planner, you need a Google Ads account. Once you are logged in, click on the wrench icon (Tools and Settings) in the top navigation bar, then select “Keyword Planner” under the Planning section.

Discover New Keywords Feature

This feature lets you enter your seed keywords or your website URL, and Google will generate a list of related keyword ideas. Here is how to use it effectively:

Enter one or more of your seed keywords in the search box.
Optionally, enter your website or landing page URL to help Google understand your business context.
Set your target location – for local businesses, narrow this down to your city or region.
Set your language to match your target audience.
Click ‘Get Results’ and review the keyword ideas Google generates.

Google Keyword Planner will show you a table of keyword suggestions with the following columns:

Keyword: The suggested word or phrase
Average Monthly Searches: How many times this keyword is searched per month (shown as a range)
Competition: Shown as Low, Medium, or High – this reflects how many advertisers are bidding on the keyword
Top of Page Bid (Low Range): The lower end of what advertisers typically pay for a top-of-page ad
Top of Page Bid (High Range): The higher end of typical bids

Get Search Volume and Forecasts Feature

If you already have a list of keywords and want to check their search data, use this feature instead. Paste your keywords in, and Google will show you the monthly search volume, competition level, and bid estimates for each one.

💡 Pro Tip
Google Keyword Planner shows search volume in broad ranges (like 1K–10K) rather than exact numbers unless your account has active campaigns spending money. Even with ranges, the data is valuable enough to make sound decisions.

Step 4: Analyze Key Metrics for Each Keyword

Once you have a list of keyword suggestions, you need to evaluate them using the following metrics:

Average Monthly Search Volume

This tells you how much demand exists for a keyword. A keyword with 50,000 monthly searches has a lot of people searching for it, but it will also be more competitive. A keyword with 500 monthly searches is less competitive and more targeted. For most small-to-medium businesses, keywords with 100 to 10,000 monthly searches are the sweet spot.

Competition Level

In Google Keyword Planner, competition is shown as Low, Medium, or High. High competition means many advertisers are bidding on that keyword, which drives up the cost per click. As a beginner or a business with a limited budget, starting with low-to-medium competition keywords is a smart strategy.

Bid Estimates (Cost Per Click)

The top of page bid range shows you approximately how much you can expect to pay each time someone clicks your ad for that keyword. Use this to estimate your campaign budget. If your target keyword has a bid of $5 per click and you want 100 clicks per week, you need a weekly budget of at least $500.

Keyword Relevance

Not every keyword Google suggests will be relevant to your business. Always ask yourself: “If someone searches for this keyword and clicks my ad, would they find exactly what they are looking for on my landing page?” If the answer is no, that keyword is not a good fit.

Step 5: Use Additional Keyword Research Tools

While Google Keyword Planner is the primary tool, using additional research methods gives you a more complete picture and helps you find keywords your competitors may have missed.

Google Search Suggest (Autocomplete)

Start typing a search query in Google and look at the autocomplete suggestions that drop down. These are real searches that people frequently make. For example, typing “plumber Denver” might show autocomplete suggestions like “plumber Denver same day,” “plumber Denver cost,” and “plumber Denver reviews.” These are valuable keyword ideas straight from real user behavior.

Google Trends

Google Trends is a free tool that shows you how search interest in a keyword has changed over time. This is useful for spotting seasonal trends. For example, searches for “pool installation” spike in spring and summer. Knowing this, you would want to increase your ad spend during those months. Google Trends also lets you compare multiple keywords side by side to see which is growing in popularity.

Competitor Research

Look at what keywords your competitors are targeting. You can do this manually by searching for your main keywords and noting which competitors consistently show up in the ads. Tools like SEMrush, Ahrefs, SpyFu, and Ubersuggest allow you to enter a competitor’s website and see which keywords they are bidding on – giving you a roadmap of what is working in your industry.

Answer the Public

Answer the Public is a free tool that generates question-based keywords from a seed term. For example, entering “plumber” might reveal questions like “how much does a plumber cost,” “what does a plumber fix,” and “when to call a plumber.” These can be excellent keywords for informational campaigns or for understanding what your customers want to know.

Step 6: Build Your Keyword List and Group by Theme

By now, you should have a large list of keyword ideas from multiple sources. The next step is to organize them into logical groups called ad groups.

An ad group is a collection of related keywords that all share a common theme, and using Bandy AI to produce visuals for each theme can make your ads more engaging and on-brand. You create a separate ad for each ad group that speaks directly to that theme. This structure keeps your ads highly relevant to the keywords, which improves Quality Score and performance.

For example, a plumbing company might have the following ad groups:

Emergency Plumbing Services (keywords: emergency plumber, 24 hour plumber, urgent plumber near me)
Drain Cleaning (keywords: drain cleaning service, unclog drain, slow drain repair)
Water Heater Repair (keywords: water heater repair, fix water heater, hot water not working)
Pipe Repair (keywords: leaking pipe repair, burst pipe fix, pipe replacement)

Notice how each group focuses on one specific service. The ad for the Emergency Plumbing group can say “Available 24/7 for plumbing emergencies” while the Water Heater group can say “Same-Day Water Heater Repair.” This relevance is what makes the difference.

Step 7: Identify and Add Negative Keywords

Negative keywords are words or phrases that you do not want your ads to appear for. They are just as important as your regular keywords – perhaps even more so – because they protect your budget from irrelevant clicks.

For example, a luxury hotel that bids on “hotel in New York” might want to add negative keywords like “cheap,” “budget,” “hostel,” and “free” to prevent their ads from showing to people looking for low-cost accommodation.

Here are common categories of negative keywords to consider:

Irrelevant topics: Terms related to your industry but not your specific service (e.g., a residential plumber might add “commercial” as a negative keyword)
Price-sensitive terms: “Free,” “cheap,” “low cost” if you sell premium products
DIY terms: “How to,” “DIY,” “tutorial,” “guide” if you sell professional services
Job seeker terms: “Jobs,” “careers,” “hiring,” “salary” to avoid job seekers clicking your ads
Competitor brand names: Avoid showing for competitor name searches unless you specifically want to target them

💡 Pro Tip: The Negative Keywords Habit
Review your Search Terms report regularly (found in Google Ads under Keywords > Search Terms). This shows you the actual searches that triggered your ads. Any irrelevant term you find there should be added to your negative keyword list.

5. Advanced Keyword Research Strategies

5.1 Understanding Search Intent at a Deeper Level

Beyond the basic categories of informational, navigational, and transactional, search intent can be even more nuanced. Google itself has become very good at understanding what a searcher truly wants – not just the words they typed. As an advertiser, you should think the same way.

Consider the keyword “best running shoes.” Is the searcher ready to buy? Probably not just yet – they are in research mode, comparing options. They might click your ad, but they need more convincing before they convert. Your landing page and ad messaging for this keyword should focus on education and comparison rather than a hard sell.

Now consider “buy Brooks Ghost 16 men’s running shoes size 10.” This person knows exactly what they want. They are ready to purchase. Your landing page should make it as easy as possible to complete that transaction.

Reading intent correctly means your ads and landing pages will resonate more deeply with searchers, leading to higher Quality Scores and better conversion rates.

5.2 Competitor Keyword Analysis

One of the most time-efficient ways to find strong keywords is to analyze what is already working for your competitors. They have likely already done extensive testing and research, so you can benefit from their efforts.

Here is a simple process for competitor keyword analysis:

Identify your top 3–5 competitors – these are businesses that consistently show up in Google search results for your main keywords.
Use a tool like SEMrush, SpyFu, or Ubersuggest to look up their websites and see which keywords they are bidding on in Google Ads.
Look for keywords that appear across multiple competitors – these are likely proven performers in your industry.
Look for gaps – keywords that have decent search volume but your competitors are not targeting. These can be valuable opportunities.
Review your competitors’ ad copy to understand their messaging, unique selling points, and offers.

5.3 Using Customer Language vs. Industry Jargon

A common mistake that business owners and marketers make is using industry terminology that their customers do not actually use. As a professional in your field, you might call your service “HVAC system maintenance,” but your customers might search for “AC tune-up” or “air conditioner service.”

To bridge this gap, spend time listening to how your customers actually describe their problems. Look at reviews on Google, Yelp, and Amazon. Read forums and community boards in your industry. Talk to your customer-facing team about the questions they hear most often. The language your customers use naturally is exactly the language you should be targeting in your keyword research.

5.4 Local Keyword Strategies

If your business serves a specific geographic area, local keyword research is critical. Local keywords typically include the name of a city, neighborhood, region, or the phrase “near me.”

Strategies for local keyword research:

Include your city, borough, or neighborhood name alongside service keywords (e.g., “dentist Austin TX,” “pizza delivery Brooklyn”)
Target “near me” keywords, as Google will automatically match these to users in your area
Consider nearby cities or suburbs where your potential customers might live
Use Google’s location targeting settings to further narrow your audience geographically
Include local landmarks or neighborhood names if relevant (e.g., “gym near downtown Nashville”)

5.5 Seasonal Keyword Planning

Many businesses have seasonal peaks and valleys in demand. Planning your keyword strategy around these patterns helps you allocate budget more efficiently.

Use Google Trends to look up your main keywords and observe their historical search volume patterns. A tax preparation service will see searches spike in January through April. A costume shop peaks in October. A pool supply company sees summer surges. Plan to increase your bids and budget for high-traffic seasonal keywords before peak periods begin – do not wait until you are in the middle of the season.

6. Evaluating Keywords: How to Choose the Best Ones

After all your research, you will likely have a large list of keyword candidates. Here is a practical framework for deciding which keywords to prioritize:

6.1 The Relevance Test

Ask: If someone searches this keyword and clicks my ad, will they find exactly what they are looking for on my page? If yes, it passes the relevance test. If there is any doubt, the keyword may not be a good fit for this campaign.

6.2 The Volume vs. Competition Balance

High-volume keywords attract more traffic but cost more and are harder to compete on. Low-volume keywords are cheaper but bring fewer visitors. The ideal keyword has a reasonable balance – enough search volume to make an impact, but not so much competition that the cost per click eats up your budget.

For smaller budgets, lean toward long-tail keywords with moderate volume (100–2,000 monthly searches) and lower competition. As your campaigns mature and you gather data, you can gradually target more competitive terms.

6.3 The Commercial Intent Indicator

Look for words in the keyword that suggest commercial intent. Words like “buy,” “order,” “hire,” “book,” “get a quote,” “best,” “affordable,” “near me,” and “service” all indicate that the person is closer to taking action. Prioritize keywords with strong commercial intent for your core campaigns.

6.4 The Profitability Calculation

Always ask whether a keyword can be profitable for your business. Here is a simple way to calculate it:

Suppose a keyword has a cost per click of $4. If your landing page converts 5% of visitors into customers, you are paying 20 clicks per customer, which means $80 per customer acquisition. If your average customer is worth $500 in revenue, this keyword is highly profitable. If your average order value is $50, you would be losing money on every customer.

Understanding your target cost per acquisition (CPA) before you start building your keyword list will help you make smarter choices from the beginning.

💡 The Profitability Anchor
Always know your maximum allowable cost per conversion before bidding on keywords. Divide your average profit per customer by your target ROAS (Return on Ad Spend) to get this number. This becomes your anchor for all keyword budget decisions.

7. Organizing Keywords for Campaign Success

7.1 Campaign and Ad Group Structure

A well-organized Google Ads account looks like this:

Campaign Level: Defined by a broad goal, budget, and location/device targeting. For example, one campaign for each major product or service line.
Ad Group Level: A cluster of closely related keywords within a campaign. Each ad group has its own ads tailored to that keyword cluster.
Keyword Level: The individual keywords within each ad group that trigger your ads.

For example, a dentist’s office might have the following structure:

Campaign	Ad Group	Sample Keywords
General Dentistry	Teeth Cleaning	teeth cleaning, dental cleaning near me, dental checkup
General Dentistry	Tooth Extraction	tooth extraction, wisdom tooth removal, emergency tooth pull
Cosmetic Dentistry	Teeth Whitening	teeth whitening service, professional teeth whitening
Cosmetic Dentistry	Dental Veneers	dental veneers, porcelain veneers, smile makeover

7.2 The SKAG Method (Single Keyword Ad Groups)

A more advanced organizational strategy is the Single Keyword Ad Group (SKAG) method. In this approach, each ad group contains only one keyword (with all three match types – broad match, phrase match, and exact match of that one keyword). This gives you maximum control over which ad shows for which keyword and allows for highly customized ad copy.

SKAGs are more time-intensive to set up but can produce excellent results in terms of Quality Score and relevance. If you have a small list of high-priority keywords and a tight budget, SKAGs are worth considering.

7.3 Using a Keyword Spreadsheet

Before uploading keywords into Google Ads, it is highly recommended to organize them in a spreadsheet first. Your keyword spreadsheet should include columns for:

Keyword
Match type
Ad group assignment
Monthly search volume
Competition level
Estimated bid
Notes or priority level

This spreadsheet becomes your master reference document. It helps you spot duplicates, identify gaps, and make systematic decisions about which keywords to prioritize when setting bids.

8. Common Keyword Research Mistakes to Avoid

8.1 Targeting Only Broad, Generic Keywords

Many beginners make the mistake of going after the biggest, most searched keywords in their industry – words like “shoes,” “insurance,” or “restaurant.” These keywords are so broad that your ad will appear for thousands of irrelevant searches. The traffic is unfocused, the cost is high, and the conversion rate is usually terrible.

Instead, start specific. Build your campaign around long-tail keywords with clear intent. You can always expand to broader keywords later once you have data and budget to support it.

8.2 Ignoring Negative Keywords

Skipping negative keywords is one of the most expensive mistakes an advertiser can make. Without a solid negative keyword list, your ads will show for all sorts of irrelevant searches. Every irrelevant click costs you money without any chance of a return.

Make negative keyword research part of your initial setup process, and revisit your Search Terms report at least once a week to catch new irrelevant terms.

8.3 Not Considering Match Types

Using only broad match keywords without a negative keyword strategy can quickly drain your budget on unrelated traffic. Conversely, using only exact match keywords can severely limit your reach. A balanced combination of match types – with broad match for discovery, phrase match for moderate control, and exact match for your highest-priority terms – is generally the most effective approach.

8.4 Setting and Forgetting Your Keywords

Keyword research is not a one-time task. Search trends change. New competitors enter the market. Consumer language evolves. Your own business offerings may expand. Plan to review and refresh your keyword list at least monthly. Look for opportunities to add new keywords and remove underperforming ones.

8.5 Copying Competitors Blindly

While competitor research is valuable, blindly copying their keyword list is a mistake. You do not know which of their keywords are actually profitable versus which ones they are testing and losing money on. Use competitor research as inspiration and a starting point, not as a final answer.

8.6 Neglecting Mobile Search Behavior

More searches happen on mobile devices than on desktop computers. Mobile searchers often use different language – shorter queries, voice search phrases, and “near me” searches. Make sure your keyword research accounts for mobile behavior. Review your device performance reports in Google Ads to understand if mobile traffic is converting well and adjust your bids accordingly.

10. Putting It All Together: A Practical Example

Let us walk through a complete keyword research example from start to finish. Imagine you own a bakery in Chicago that specializes in custom wedding cakes.

Step 1: Define Your Goal and Audience

Goal: Get inquiries and consultations for custom wedding cake orders. Target audience: Engaged couples in the Chicago area planning their weddings. They are likely searching for local bakeries that specialize in custom wedding cakes and are willing to pay a premium for quality.

Step 2: Brainstorm Seed Keywords

custom wedding cakes
wedding cake bakery
wedding cake Chicago
wedding cake design
tiered wedding cakes
cake tasting appointment

Step 3: Research in Google Keyword Planner

After entering these seeds into Google Keyword Planner with a target location of Chicago, IL, you discover additional ideas including:

custom wedding cake Chicago – 480 monthly searches, Medium competition, $2.80–$4.20 bid
wedding cake bakery near me – 1,300 monthly searches, High competition, $3.50–$5.60 bid
wedding cake designer Chicago – 260 monthly searches, Low competition, $2.10–$3.40 bid
best wedding cake Chicago – 390 monthly searches, Medium competition, $2.90–$4.50 bid
fondant wedding cake Chicago – 90 monthly searches, Low competition, $1.80–$2.80 bid
naked cake wedding Chicago – 140 monthly searches, Low competition, $1.60–$2.50 bid

Step 4: Identify Negative Keywords

Using Google Autocomplete and the Related Searches section, you discover that many people also search for:

wedding cake recipes – these people want to bake their own cake, not buy from you
cheap wedding cakes – you are a premium bakery
wedding cake topper – this is a product, not a service
wedding cake images – people browsing for inspiration, not ready to order

You add these to your negative keyword list: recipe, DIY, how to make, cheap, budget, topper, images, photos, ideas.

Step 5: Organize Into Ad Groups

You create three ad groups:

Custom Wedding Cakes Chicago: custom wedding cake Chicago, wedding cake designer Chicago, best wedding cake Chicago
Wedding Cake Bakery: wedding cake bakery near me, wedding cake shop Chicago, cake bakery Chicago
Specialty Wedding Cake Styles: fondant wedding cake Chicago, naked cake wedding Chicago, tiered wedding cake Chicago

Each ad group will have its own tailored ad. The Custom Wedding Cakes ad might read: “Bespoke Wedding Cakes Chicago – Designed Just for Your Special Day. Free Tasting Consultation.” The Specialty Styles ad might read: “Naked Cakes, Fondant Cakes & More – Chicago’s Custom Wedding Cake Experts.”

This is the power of a well-organized keyword structure – each ad speaks directly to what the searcher is looking for, which improves relevance, Quality Score, and ultimately, conversions.

11. Ongoing Keyword Management and Optimization

Building your initial keyword list is just the beginning. Successful advertisers treat keyword management as an ongoing process that continues for as long as their campaigns run.

11.1 The Search Terms Report: Your Best Friend

The Search Terms report in Google Ads shows you the exact phrases people typed into Google that triggered your ads. This report is invaluable for two reasons: first, you can discover new keyword opportunities that you had not thought of originally. Second, you can find irrelevant terms to add to your negative keyword list.

Make it a habit to review this report at least once a week during the early months of your campaign. As your campaign matures and your negative keyword list grows, you can check it less frequently.

11.2 Pausing Underperforming Keywords

Not every keyword will perform equally. After running your campaigns for at least two to four weeks (longer for lower-traffic keywords), look at which keywords have received enough clicks to measure their performance. Keywords that have spent a significant portion of your budget without generating conversions should be paused or removed.

The general rule of thumb is: if a keyword has received 50–100 clicks with zero conversions, it is a strong signal that either the keyword is wrong, the ad copy is off, or the landing page is not delivering what the searcher expected. Pause the keyword and investigate why.

11.3 Bid Adjustments Based on Performance

Once you have enough data, use it to adjust your bids intelligently. Increase bids on keywords that are converting profitably – this will show your ads more often and in higher positions for those terms. Decrease bids on keywords that are generating clicks but not conversions, or that are profitable but at a lower margin.

Google Ads also allows you to set bid adjustments for specific devices, times of day, and geographic locations. Use your performance data to take advantage of these settings. For example, if your ads convert twice as well on mobile devices, you might increase your mobile bid adjustment by 50%.

11.4 Adding New Keywords Over Time

As you gather data from your Search Terms report and as your business evolves, continuously add new keywords to your campaigns. Look for patterns in the search terms that are converting – these are golden opportunities that your initial research may have missed.

Also stay alert to changes in your industry. New products, new trends, and changes in consumer behavior all create new keyword opportunities. Google Trends can help you stay ahead of emerging search terms.

Conclusion

Keyword research is both a science and an art. The science comes from data – search volumes, bid estimates, competition levels, and performance metrics. The art comes from understanding your customers deeply – the language they use, the problems they face, and the intent behind their searches.

If you follow the step-by-step process in this guide – starting with a clear goal, building a thoughtful seed list, using Google Keyword Planner and complementary tools, selecting the right match types, organizing your keywords into logical ad groups, and maintaining your campaigns with regular reviews – you will be well ahead of the majority of advertisers who simply guess at what keywords to use.

Remember that keyword research is not something you do once and forget. The best advertisers treat it as an evolving process, continually learning from their data, testing new ideas, and refining their approach. Even a small improvement in your keyword strategy can have a significant impact on your campaign’s profitability.

Start with the basics, be patient with the learning curve, and let the data guide your decisions. With time and practice, keyword research will become one of your most powerful skills as a Google Ads advertiser.
