Every click costs money. The real question is whether you’re paying a fair price for that click, or whether Google is quietly charging you a premium because your ads don’t closely match what your customers are actually searching for.
This is the ad relevance problem, and it affects more local business campaigns than most owners realize. When the language in your ad doesn’t align with the search query that triggered it, Google interprets that as a mismatch. A mismatch means a lower Quality Score. A lower Quality Score means you pay more per click and compete for worse positions, even against advertisers with smaller budgets who simply wrote better ads.
Ad relevance is one of the most controllable performance levers in Google Ads. Unlike your bid strategy or your competition’s budgets, ad relevance is entirely within your power to fix. It comes down to three things working together: the keyword a user searches, the ad copy they see, and the landing page they land on. When all three speak the same language, Google rewards you. When they don’t, you pay the penalty.
The good news is that improving ad relevance doesn’t require a bigger budget. It requires a more disciplined structure. This guide walks through six concrete steps to help you systematically improve ad relevance, raise your Quality Scores, and get more leads from the budget you’re already spending.
These aren’t theoretical concepts. They’re the same structural and copy principles that PPC professionals use to build campaigns that actually convert. Whether you’re managing your own Google Ads account or reviewing the work of someone who manages it for you, these steps give you a clear framework for diagnosing problems and making meaningful improvements.
No padding, no filler. Just the actions that move the needle on how to improve ad relevance for your specific business.
Step 1: Audit Your Current Quality Score and Ad Relevance Diagnostics
Before you change anything, you need to know exactly where you stand. Jumping straight into rewriting ads without first understanding which keywords are underperforming is like renovating a house without checking which walls are load-bearing. You might fix the wrong things entirely.
Google Ads gives you the diagnostic data you need. Here’s how to find it.
Navigate to your Keywords tab in the Google Ads interface. By default, Quality Score columns aren’t visible, so you’ll need to add them manually. Click the columns icon, select “Modify columns,” then look under the “Quality Score” category. Add the following columns: Quality Score, Expected CTR, Ad Relevance, and Landing Page Experience. Save this view.
You’ll now see each keyword rated on a 1-10 Quality Score scale, along with three sub-component ratings: Above Average, Average, or Below Average. These three components are how Google breaks down what’s driving your score up or pulling it down.
Expected CTR reflects whether Google predicts people will click your ad when they see it, based on historical data for that keyword.
Ad Relevance measures how closely your ad copy matches the intent behind the user’s search query. This is the component this guide focuses on most directly.
Landing Page Experience reflects whether your destination page is relevant, fast, and useful to someone who clicked your ad.
Once your columns are visible, filter your keyword list to show only keywords with “Below Average” Ad Relevance. Sort by cost to identify which of these underperformers are consuming the most budget. This is your priority list.
Keywords with consistently Below Average Ad Relevance that are spending money without converting deserve immediate attention. In some cases, the right short-term move is simply to pause them while you restructure the ad group around them. Letting a poorly aligned keyword continue spending is effectively paying a penalty tax on every click. For a deeper dive into diagnosing and fixing this issue, see our guide on low Quality Score in Google Ads.
This diagnostic step also sets your baseline. When you implement the changes in Steps 2 through 5, you’ll want to return to these columns two to four weeks later to measure whether your ratings have improved. Improvement in Ad Relevance and Expected CTR typically leads to better Quality Scores over time, which in turn affects what you pay per click and how often your ads are shown.
You can’t improve what you haven’t measured. This audit is where every relevance improvement begins.
Step 2: Restructure Campaigns Into Tightly Themed Ad Groups
If the audit in Step 1 revealed widespread Below Average Ad Relevance across many keywords, the root cause is almost always structural. Specifically, it’s the result of stuffing too many loosely related keywords into a single ad group.
Here’s why this matters. Every ad group shares the same set of ads. If your ad group contains 40 keywords covering a broad range of services, you’re forced to write ad copy that tries to speak to all of them at once. The result is generic copy that doesn’t closely match any single search query. Google reads that mismatch and rates your Ad Relevance as Below Average. You pay more. Your ads show less.
The fix is to break your ad groups into tightly themed clusters, where every keyword in the group is closely related enough that a single set of ads can speak directly and specifically to all of them.
A good rule of thumb is 5 to 15 closely related keywords per ad group, though the number matters less than the thematic tightness. Every keyword in the group should share the same core intent, service type, and ideally the same language.
Consider a pest control company running Google Ads. A common mistake would be to create one ad group called “pest control” and dump in keywords like “termite inspection,” “ant removal,” “rodent control,” “bed bug treatment,” and “cockroach exterminator.” These services are related, but they’re not the same. Someone searching “termite inspection” has a completely different concern from someone searching “rodent control.” Writing one ad that speaks to both means speaking precisely to neither.
The better structure splits these into separate ad groups: one for termite-related keywords, one for ant-related keywords, one for rodent control, and so on. Now each ad group can have headlines and descriptions written specifically for that pest, that problem, and that customer’s intent. This kind of disciplined restructuring is one of the most effective Quality Score improvement tactics available to advertisers.
This approach is sometimes called single-theme ad groups in the PPC industry, and it’s widely recommended precisely because it makes high-relevance ad copy possible. You can’t write a hyper-specific headline if your ad group is too broad to have a specific focus.
For local businesses, this restructuring also creates a natural opportunity to layer in geographic specificity. A “termite inspection” ad group for a pest control company serving Atlanta can include keywords like “termite inspection Atlanta” alongside “termite inspection near me,” and the ads can be written to reflect that local context.
This structural work is foundational. Everything in Steps 3 and 4 depends on having ad groups tight enough to support specific, relevant messaging. Skipping this step and jumping straight to rewriting ads is like repainting a cracked wall without fixing the foundation underneath.
Step 3: Rewrite Ad Copy to Mirror Search Intent Word-for-Word
Once your ad groups are structured around tight themes, you have the foundation to write ad copy that actually earns high Ad Relevance ratings. The core principle here is straightforward: your headline should echo the exact language your prospect typed into Google.
This isn’t about being clever. It’s about being recognized. When someone searches “emergency plumber in Dallas” and your headline reads “Emergency Plumber in Dallas,” they immediately see confirmation that your ad is exactly what they were looking for. That recognition drives clicks, and clicks signal relevance to Google.
With Responsive Search Ads (RSAs) now the standard format in Google Ads, you have the ability to provide up to 15 headlines and 4 descriptions. Google’s system tests combinations and optimizes for performance. This is useful, but it also introduces a risk: if you provide 15 generic headlines, Google will rotate generic combinations and your Ad Relevance can still suffer. For a complete walkthrough on getting the most from this ad format, check out our guide on how to optimize responsive search ads.
The smarter approach is to write your first three to five headlines specifically around your ad group’s core theme, using the exact language your keywords reflect. Then use the remaining headline slots for supporting messages like trust signals, offers, or calls to action.
One powerful RSA feature worth using deliberately is headline pinning. You can pin a specific headline to Position 1, ensuring it always appears regardless of which combination Google selects. For ad relevance purposes, pin your most query-specific headline to Position 1 so that the most relevant message is always visible.
You also have the option of keyword insertion, a dynamic feature that automatically swaps in the triggering keyword into your headline. This can boost relevance quickly, but use it carefully. Keyword insertion works well for simple, clean keyword phrases. It breaks down when your keywords are long or awkwardly phrased, producing headlines that read strangely to a real person.
The most common ad copy mistake that tanks Ad Relevance is writing brand-focused copy instead of query-matching copy. Headlines like “We’re Your Trusted Local Plumber” or “Family-Owned Since 1998” are about you, not about what the searcher needs. Someone searching “burst pipe repair tonight” doesn’t want your company story in the headline. They want confirmation that you fix burst pipes, that you’re available now, and that you serve their area. Lead with that.
Your descriptions should reinforce the relevance established in the headline. Address the specific problem, name the specific service, and include a location reference if applicable. End with a clear call to action that matches the intent behind the search.
Step 4: Align Landing Pages With Each Ad Group’s Promise
Here’s a pattern that quietly destroys ad relevance for local businesses: a well-structured ad group, well-written headlines, and then every click sends the visitor to the homepage.
The homepage is designed to introduce your entire business. It’s not designed to fulfill the specific promise of a specific ad. When someone clicks an ad for “termite inspection in Phoenix” and lands on a generic pest control homepage, the connection breaks. Google’s algorithm notices. Your Landing Page Experience rating drops to Below Average, dragging down your overall Quality Score along with it.
The fix is to create or adapt landing pages so that the headline, content, and call to action directly match what the ad group is about. This doesn’t necessarily mean building dozens of completely separate websites. It can mean creating dedicated service pages, or even simple landing pages, that speak specifically to the service and intent the ad group targets.
According to Google’s own Quality Score documentation, Landing Page Experience is evaluated based on several factors: the relevance of the page content to the ad and search query, page load speed, mobile usability, and how easy it is for visitors to find what they’re looking for. Each of these is worth addressing.
Content relevance: The landing page headline should reflect the same language as the ad. If your ad says “Same-Day Termite Inspection,” your landing page should lead with that phrase or something very close to it. Don’t make visitors hunt for confirmation that they’re in the right place.
Page speed and mobile usability: Google’s PageSpeed Insights tool is free and gives you a direct read on how your page performs on mobile. For local businesses, a significant portion of search traffic comes from mobile devices. A slow or poorly formatted mobile page loses both visitors and Quality Score points. If your bounce rates are climbing, our guide on how to fix a high bounce rate walks through the most common culprits.
Local trust signals: For local businesses specifically, landing pages should include elements that build confidence quickly. This means visible reviews or star ratings, relevant certifications or licenses, a local phone number that’s easy to tap on mobile, and a short form above the fold for visitors who prefer to inquire online.
The goal is alignment at every stage of the click journey. The keyword matches the ad. The ad matches the landing page. The landing page delivers on the ad’s promise. When that chain is tight, Google sees it, your Quality Score reflects it, and your website conversion rate typically improves over time.
Step 5: Build a Negative Keyword List That Eliminates Irrelevant Traffic
There’s a less obvious way that ad relevance gets damaged, and it has nothing to do with your ad copy or landing pages. It comes from the wrong people clicking your ads in the first place, and from the even larger number of wrong people who see your ads and don’t click.
Every time your ad appears for a search that isn’t relevant to your business, one of two things happens. Either someone clicks it, costing you money for a visitor who will never convert. Or no one clicks it, which drives down your click-through rate and signals to Google that your ad isn’t relevant to that type of search. Both outcomes hurt your Expected CTR component, which feeds into your overall Quality Score.
Negative keywords are the tool that prevents this. Per Google’s own documentation, negative keywords stop your ads from showing on searches that include those terms, keeping your traffic cleaner and your relevance signals stronger. This is also one of the fastest ways to reduce ad spend waste in any campaign.
The most valuable source of negative keywords is your Search Terms Report. You’ll find it under the Keywords tab in Google Ads. This report shows the actual queries that triggered your ads, which is often very different from the keywords you’re bidding on. Review it weekly, especially in the early weeks of a campaign or after any structural changes.
Look for patterns in the irrelevant queries. Common categories worth building into a proactive negative keyword list include:
DIY and how-to searches: Terms like “how to,” “DIY,” “myself,” or “tutorial” signal someone looking to solve the problem without hiring anyone.
Job seekers: Terms like “jobs,” “careers,” “hiring,” “salary,” or “apply” indicate someone looking for employment, not a service provider.
Free-seekers: Terms including “free,” “no cost,” or “cheap” may attract visitors who aren’t a match for your pricing or service model.
Unrelated services: If you’re a residential pest control company, searches for “commercial pest control contracts” or “pest control franchise” are irrelevant and should be excluded.
Competitor names: Unless you’re intentionally running competitor campaigns, competitor brand names often generate low-relevance clicks.
The compounding effect of consistent negative keyword management is significant. Cleaner traffic means a higher percentage of people who see your ad actually click it. A higher click-through rate improves your Expected CTR rating. A better Expected CTR improves your Quality Score. A better Quality Score lowers what you pay per click. If you’re seeing unqualified visitors eating into your budget, our article on why your leads are not qualified enough covers additional strategies to tighten targeting.
Step 6: Test, Measure, and Refine on a 2-Week Cycle
The five steps above are not a one-time project. They’re the foundation of an ongoing optimization discipline. Step 6 is about building the testing and measurement habits that turn a good campaign into a great one over time.
The most important rule in ad testing is to change one variable at a time. If you rewrite your headlines, change your landing page, and restructure your ad groups simultaneously, you won’t know which change drove the improvement or caused the drop. Test one element, measure the result, then move to the next.
A two-week testing cycle works well for most local business campaigns. It gives enough time to accumulate statistically meaningful data without letting underperforming variations run too long. At the end of each cycle, review the following metrics:
Quality Score and Ad Relevance ratings: Are your Below Average keywords moving toward Average or Above Average? This is your primary indicator that the structural and copy changes are working.
Click-through rate: Is a higher percentage of people who see your ad actually clicking it? Rising CTR is a strong signal of improved relevance.
Conversion rate and cost per conversion: Clicks are a means to an end. The real measure of campaign health is whether those clicks are turning into leads, calls, or sales at a cost that makes business sense. If your cost per conversion remains stubbornly high even after relevance improvements, our guide on the high cost per conversion problem can help you diagnose what else may be going wrong.
When you implement the changes from Steps 1 through 5 and then return to your Quality Score columns two to four weeks later, you should begin to see movement in your Ad Relevance and Expected CTR ratings. Improvements there typically compound into better overall Quality Scores over subsequent weeks.
One important signal to watch for: if you’ve restructured your ad groups, rewritten your copy, and aligned your landing pages, but a specific keyword’s Ad Relevance stays Below Average, that may indicate a keyword-market mismatch. The keyword might be attracting searchers whose intent doesn’t align with what you actually offer. In that case, the right answer isn’t more optimization. It’s pausing that keyword and reconsidering whether it belongs in your campaign at all.

Your Ad Relevance Action Checklist
Here’s a quick-reference summary of the six steps covered in this guide:
1. Audit Quality Score diagnostics. Add Quality Score columns to your Keywords tab. Filter for Below Average Ad Relevance. Pause high-spend keywords with persistent relevance problems while you restructure.
2. Restructure into tightly themed ad groups. Break broad ad groups into clusters of closely related keywords. Each group should share the same intent and service focus so specific ad copy is possible.
3. Rewrite ad copy to mirror search intent. Lead with query-specific headlines. Pin your most relevant headline to Position 1 in RSAs. Avoid generic brand-focused copy in favor of copy that directly addresses what the searcher needs.
4. Align landing pages with each ad group. Stop sending all traffic to your homepage. Build or adapt pages that match the ad’s promise, load quickly on mobile, and include local trust signals and a clear call to action.
5. Build and maintain negative keyword lists. Review your Search Terms Report weekly. Exclude DIY searches, job seekers, free-seekers, and unrelated service terms. Cleaner traffic compounds into better CTR and lower costs over time.
6. Test and refine on a 2-week cycle. Change one variable at a time. Track Quality Score, CTR, and cost per conversion. If relevance scores stay Below Average after restructuring, reconsider whether the keyword belongs in the campaign.
Improving ad relevance isn’t a one-time fix. It’s an ongoing discipline that builds on itself. Each improvement in structure, copy, and landing page alignment compounds into better scores, lower costs, and more leads from the same budget.
