How to Improve Ad Relevance in Google Ads: A Step-by-Step Guide

TL;DR: Ad relevance is one of three factors that make up your Quality Score in Google Ads. When it's low, you pay more per click and show up less often. This guide walks you through exactly how to improve ad relevance—step by step—so your ads match what people are actually searching for, your Quality Score climbs, and your budget goes further. Whether you're managing one campaign or dozens, these steps apply directly to your Search Terms Report workflow. No fluff, just a practical process you can start using today.

Most Google Ads accounts I audit have the same problem: ad groups that are too broad, ad copy that's too generic, and a Search Terms Report full of queries that have nothing to do with what the ads actually say. The result? Ad relevance ratings stuck at "Below Average" and CPCs that are higher than they need to be.

The good news is that ad relevance is probably the most controllable of the three Quality Score components. You can't fully control what Google predicts your CTR will be, and landing page experience involves technical factors that take time to fix. But ad relevance? That's largely a copy and structure problem, and copy and structure are things you can change today.

Here's exactly how to do it.

Step 1: Understand What Ad Relevance Actually Measures

Before you start making changes, it helps to know what Google is actually evaluating. Ad relevance is Google's assessment of how closely your ad copy matches the intent behind a user's search query. Notice that phrasing: it's about intent, not just keyword presence.

This is the most common misconception I see. Advertisers stuff their target keyword into every headline and description, assume that's enough, and wonder why their relevance score hasn't moved. Keyword presence is a starting point, not the finish line. Google is trying to determine whether your ad actually addresses what the person is trying to accomplish.

Quality Score has three components: expected CTR, landing page experience, and ad relevance. Each is rated separately as "Below Average," "Average," or "Above Average." The overall Quality Score is a 1-10 number visible at the keyword level, and it directly influences your Ad Rank, which determines both where your ad shows and what you actually pay per click. Understanding what causes low Quality Score is essential before you can fix it systematically.

To find your ad relevance ratings, go to the Keywords tab in Google Ads, click Columns, then Modify Columns, and look for the Quality Score section. Add "Ad Relevance" to your view. Do this now, before making any changes, so you have a baseline to measure against. You want to know which keywords are sitting at "Below Average" so you can prioritize your effort.

A keyword rated "Below Average" for ad relevance is essentially Google telling you: the ad this keyword is triggering doesn't match what people searching this term actually want. That's your starting point for every fix in this guide.

Step 2: Audit Your Search Terms Report for Intent Mismatches

The Search Terms Report is ground zero for ad relevance issues. It shows you what people actually typed into Google before your ad was triggered, which is often very different from the keyword you're bidding on.

To access it: Campaigns → Insights & Reports → Search Terms. Pull data for at least the last 30 days, ideally 60-90 days if your account has enough volume.

What you're looking for falls into three categories:

Topically unrelated terms: Search terms that have nothing to do with your ad copy. If you're running ads for a PPC optimization tool and you're showing for "PPC university courses," that's a relevance gap. Your ad talks about software; the searcher wants education.

Intent mismatches: Terms that are in your industry but at the wrong stage of the funnel. If your ad says "Buy Running Shoes" but you're showing for "how to start running," the commercial intent doesn't match. One person wants to buy; the other wants information. Your ad copy is irrelevant to that second person's actual need.

Wrong audience signals: Terms from completely different use cases or industries. A B2B software tool showing for consumer searches is a classic example.

Here's why this matters for ad relevance specifically: Google sees the full picture of what's triggering your ads. When a pattern of irrelevant search terms consistently triggers a given keyword, Google's system interprets that as a mismatch between your keyword, your ad, and what users actually want. That mismatch shows up in your ad relevance score.

In most accounts I audit, this single step reveals enough junk to explain why ad relevance is stuck at "Below Average." The fix isn't just adding negatives (though that's Step 5). First, you need to understand the pattern of mismatches, because that pattern tells you how to restructure your ad groups and rewrite your copy. Learning how to improve your search terms systematically is the foundation everything else builds on.

Step 3: Build Tightly Themed Ad Groups

The core principle here is simple: one theme per ad group means your ad copy can speak directly to a narrow set of search intents. The tighter the theme, the easier it is to write ad copy that genuinely matches what someone is searching for.

Two approaches dominate the conversation: SKAGs (Single Keyword Ad Groups) and STAGs (Single Theme Ad Groups). SKAGs give you maximum control by isolating one keyword per ad group, which means you can write hyper-specific copy for exactly that keyword. The downside is that they're hard to scale and can create a management nightmare in larger accounts.

STAGs are more practical for most advertisers. You group 3-10 tightly related keywords together, write ad copy that speaks to the shared intent across all of them, and get most of the relevance benefit without the operational overhead. For the majority of accounts, STAGs hit the right balance. Understanding how match type affects ad relevance is critical when deciding which keywords belong together in each group.

A practical example: if you have one ad group called "Shoes" with keywords for running shoes, dress shoes, and kids' shoes, your ad copy is trying to speak to three completely different audiences with different needs. Split them into three separate ad groups, write copy specific to each theme, and your relevance immediately improves because each ad is now speaking to a much narrower intent.

How do you identify which ad groups need splitting? Look at your keyword list. If an ad group has 15 or more keywords with different root themes, it almost certainly needs restructuring. A quick way to check: if you can't write a single headline that genuinely applies to every keyword in the group, the group is too broad.

Keyword clustering helps enormously here. Grouping semantically related terms before you start restructuring saves hours of manual work. Rather than reviewing keywords one by one, you can see the natural themes emerge and build your new ad group structure around them. Once you've identified your clusters, restructuring becomes much more straightforward.

Step 4: Rewrite Ad Copy to Mirror Search Intent

This is where most ad relevance improvements actually happen. And it's also where most advertisers get it wrong.

The mistake is confusing keyword insertion with intent mirroring. Dynamic keyword insertion (DKI) drops the search term into your headline automatically, which can look relevant on the surface. But Google evaluates whether your ad actually addresses what the searcher wants to accomplish, not just whether the words match. An ad that says "Buy {keyword}" for every search query isn't genuinely relevant to someone who's still researching their options. Before relying on DKI, it's worth understanding the right dynamic keyword insertion tactics so you're using it to reinforce intent rather than replace it.

Think about the four dominant intent types and write copy that matches the one your ad group is targeting:

Informational intent: The person wants to learn something. Lead with insight, not a sales pitch. Your headline should promise an answer, not a product.

Navigational intent: The person is looking for a specific brand or website. If they're searching for you by name, your copy should confirm they've found the right place.

Commercial investigation: The person is comparing options before making a decision. Lead with differentiators, proof points, and what makes you the better choice.

Transactional intent: The person is ready to act. Lead with the offer, the ease of getting started, and remove friction. This is where "Free Trial," "Start Today," and "No Credit Card Required" belong.

A simple rewriting framework that works: (1) Identify the core job-to-be-done behind the search. What outcome does this person actually want? (2) Lead with that outcome in your first headline. (3) Use your description to address the next logical concern or objection.

For a keyword group around "Google Ads optimization tool," a transactional searcher wants to know the tool actually works and is easy to try. Your headline should lead with speed and simplicity, not a feature list. "Optimize Google Ads in Minutes" beats "Advanced PPC Management Software" every time for a buyer-intent audience. Pairing strong copy with the right high relevance ad copy strategy is what consistently moves the needle on your ad relevance rating.

One RSA-specific tip: in Responsive Search Ads, pin your most intent-matched headline to position 1. Google's algorithm will test combinations, but if your most relevant headline gets buried, you lose the relevance signal. Pinning ensures it always shows.

The most common pitfall I see: generic brand-focused headlines like "We're the Leading PPC Solution" instead of query-focused ones. Nobody searching "how to reduce wasted ad spend" wants to hear about your company's market position. They want to know you can solve their specific problem.

Step 5: Add Negative Keywords to Protect Relevance

Every irrelevant search term that triggers your ad is a relevance signal working against you. Google sees the mismatch between what triggered the ad and what the ad says, and that feeds directly into your ad relevance rating.

The negative keyword identification process is straightforward. Go to your Search Terms Report, sort by impressions or cost, and look for patterns in the terms that have zero or very low conversions. Ask three questions about each pattern you find:

Wrong industry or topic? These are terms that share a word with your keywords but belong to a completely different context. Add them as negatives immediately.

Wrong intent? If you're targeting buyers but showing for research queries like "how to" or "what is," you're paying for impressions that will never convert and diluting your relevance at the same time.

Wrong audience? Consumer searches triggering B2B ads, or vice versa, are a common source of wasted spend and poor relevance.

For adding negatives, use campaign-level negatives for broad exclusions that apply everywhere, and ad group-level negatives when you need to protect a specific themed group without affecting others. If "free" is irrelevant across your entire account, campaign-level makes sense. If it's only irrelevant in one ad group, keep it at the ad group level.

Shared negative keyword lists are worth building if you manage multiple campaigns. Create a list for common junk term patterns (competitor terms you don't want, irrelevant modifiers, wrong-intent qualifiers) and apply it across campaigns in one click. It's a time investment upfront that pays off every week afterward. Understanding how to eliminate junk search terms at scale is what separates accounts with clean relevance signals from those constantly fighting wasted spend.

Review your Search Terms Report at least weekly. Google's broad match and Smart Bidding systems constantly expand the range of queries your keywords can match, which means new junk terms appear regularly. A weekly audit keeps your relevance signals clean and your budget focused on queries that actually matter.

Step 6: Align Landing Pages With Ad Group Themes

Ad relevance and landing page experience are separate Quality Score components, but they influence each other more than most advertisers realize. Even if you nail your ad copy, sending traffic to a mismatched landing page undermines the entire relevance chain.

Think of it as a three-link chain: search query → ad copy → landing page. All three need to speak to the same intent. If any link breaks, the user experience degrades and Google's systems notice.

A quick checklist for landing page alignment:

Does the H1 include the core keyword theme? If your ad group is themed around "PPC optimization tool," your landing page H1 should reinforce that theme, not pivot to something generic.

Does the page deliver on the ad's specific promise? If your ad says "Try Free for 7 Days," the landing page needs to make that trial front and center. Sending someone to a homepage that buries the trial offer is a relevance break, both for Google and for the user.

Is the CTA consistent with the intent stage? A commercial investigation audience wants to learn more before committing. A transactional audience wants to start immediately. Your CTA should match where they are in the decision process.

The classic relevance break I see constantly: ad says "Try Our PPC Tool Free for 7 Days" and the landing page is a generic homepage with no mention of the trial. Google's crawlers evaluate the page, see the disconnect, and that feeds into both landing page experience and the broader relevance signals around that keyword.

The quick win here is creating dedicated landing pages per ad group theme rather than routing all traffic to your homepage. Even small copy tweaks matter: if your ad headline says "Optimize Google Ads in Minutes," your landing page H1 should echo that language. Consistency across the full chain is what Google is looking for. If you want to go deeper on this, testing different landing pages against each other is the most reliable way to find the combinations that lift both Quality Score and conversion rate.

Step 7: Monitor, Test, and Iterate Your Way to "Above Average"

Ad relevance improvement isn't a one-afternoon project. It's an ongoing optimization loop, and the advertisers who consistently hit "Above Average" ratings are the ones who've made that loop a habit.

A simple review cadence that works for most accounts: weekly Search Terms audit to catch new junk terms and flag intent mismatches, bi-weekly ad copy review to check which RSA combinations are performing and whether copy adjustments are needed, and a monthly Quality Score check to track trends at the keyword level. Knowing how to improve Quality Score in Google Ads holistically keeps all three components moving in the right direction together.

For A/B testing ad copy, the rule is simple: change one element at a time. If you change headline 1 and description 1 simultaneously, you can't tell which change drove the result. Change one thing, let it collect enough impressions to be meaningful, then evaluate CTR and conversion rate together. CTR alone can be misleading; an attention-grabbing headline that doesn't convert is just burning budget.

What "Above Average" ad relevance looks like in practice: your ads show more often at lower CPCs because Google trusts the match between your keywords, ads, and landing pages. You're not fighting for position with inflated bids; you're earning it through relevance. That's the compounding benefit of getting this right consistently over time.

One honest note on workflow: doing all of this manually across multiple campaigns is genuinely time-consuming. The Search Terms Report review alone can eat hours every week if you're exporting to spreadsheets, building negative lists in separate tabs, and then re-uploading changes. If that sounds familiar, it's a workflow problem worth solving. Tools like Keywordme let you act directly inside the Search Terms Report without leaving Google Ads, which removes the spreadsheet back-and-forth entirely and makes the weekly audit something you can actually stick to.

Track your Quality Score trends over 30-60 days after making these changes. Improvements in ad relevance typically show within 2-4 weeks of consistent optimization, though accounts with lower volume may take longer to accumulate enough data for Google to update the ratings.

Putting It All Together: Your Ad Relevance Improvement Checklist

Here's a quick-reference summary of everything covered in this guide:

✅ Check current ad relevance scores in the Keywords tab (Columns → Quality Score → Ad Relevance)

✅ Audit your Search Terms Report for intent mismatches, topically unrelated terms, and wrong-audience triggers

✅ Restructure broad ad groups into tightly themed SKAGs or STAGs so your copy can speak to a narrow intent

✅ Rewrite ad copy to mirror the dominant intent of each ad group, not just repeat keywords

✅ Add negative keywords at campaign and ad group level to block irrelevant triggers and keep relevance signals clean

✅ Align landing pages with each ad group's specific theme, including H1 language, offer consistency, and CTA intent stage

✅ Set up a weekly Search Terms audit, bi-weekly copy review, and monthly Quality Score check as an ongoing habit

Improving ad relevance isn't complicated, but it does require consistency. The advertisers who consistently hit "Above Average" ratings aren't doing anything magical. They're reviewing their Search Terms Reports regularly, keeping their ad groups tight, and writing copy that actually speaks to what someone is searching for. That's it.

If you're managing multiple campaigns and this process feels like it takes forever, that's a workflow problem worth fixing. Start your free 7-day trial of Keywordme and see how much faster this entire process gets when you can remove junk terms, build negative lists, and act on your Search Terms Report without ever leaving Google Ads. No spreadsheets, no tab-switching, just faster optimization where you're already working.
