How to Remove Irrelevant Clicks in Google Ads: A Step-by-Step Guide

TL;DR: Irrelevant clicks drain your Google Ads budget when your ads show up for searches that have nothing to do with what you sell. To fix it, you need to regularly audit your Search Terms Report, build negative keyword lists, tighten match types, refine your audience and location targeting, block suspicious IPs, and use tools that make the whole process faster. This guide walks through each step in the exact order experienced PPC managers use them.

Every Google Ads account leaks money to irrelevant clicks. Every single one. It doesn't matter if you're a solo freelancer managing a local service account or an agency running 50 client campaigns—if you haven't audited your Search Terms Report recently, you're almost certainly paying for clicks that will never convert.

Think about it this way: a plumber running broad match ads might be paying for clicks from people searching "plumbing school" or "plumbing license requirements." A SaaS company might be burning budget on "free alternatives to [their product]" or "[competitor name] vs [other competitor]." Neither of those clicks is going to turn into a customer.

The problem goes beyond just wasted spend. Irrelevant clicks tank your CTR, which signals to Google that your ads aren't relevant, which can hurt your Quality Score and raise your CPCs over time. It's a compounding problem. The longer you ignore it, the more it costs you.

Learning how to remove irrelevant clicks in Google Ads is one of the highest-ROI skills you can develop as an advertiser. It's not glamorous work, but it's the kind of disciplined account hygiene that separates accounts with a cost-per-conversion that keeps dropping from ones that plateau and stagnate.

This guide walks through the exact six-step process that experienced PPC managers use to identify and eliminate irrelevant clicks, reduce wasted spend, and squeeze more conversions from the same budget. Let's get into it.

Step 1: Audit Your Search Terms Report for Junk Queries

Before you can fix anything, you need to see what's actually happening. Navigate to Google Ads, then go to Insights & Reports > Search Terms. This is the most important report in your account that most advertisers don't check nearly enough.

Here's the thing a lot of people miss: the keywords you're bidding on and the actual search queries triggering your ads are not the same thing. Your keywords are your intentions. The Search Terms Report is reality. And the gap between those two things is where your budget leaks. Understanding how to read Google Ads reports properly is essential for catching these issues early.

Broad match, in particular, has gotten increasingly liberal over the years. Google's AI now interprets your keywords through contextual signals, which can be genuinely useful for finding new relevant traffic—but it also means Google will sometimes match you to queries that make you wonder if anyone at Google actually looked at your account. In most accounts I audit, the first Search Terms Report review surfaces at least a dozen terms that have no business being there.

When you're in the report, sort by cost first. You want to find the biggest budget drains immediately. Then sort by clicks to catch high-volume irrelevant terms that might be cheaper individually but add up fast.

As you scan, look for these patterns:

Informational queries: Searches starting with "what is," "how to," "what does," or "free" usually indicate someone in research mode, not buying mode. If you're selling project management software and someone searched "what is project management," that click probably isn't converting.

Competitor names you don't want: Sometimes broad match pulls in competitor brand terms. If you're not specifically running a competitor campaign with the right messaging and landing pages, these clicks are usually wasted.

Geographic mismatches: If you serve specific locations, look for searches that include city names or regions you don't cover.

Completely unrelated terms: These are the easiest to spot. If you sell accounting software and you're showing up for "accounting degree programs," that's a clear mismatch.

Flag everything that clearly doesn't match buyer intent. You're looking for people who are ready to buy, compare, or at minimum, seriously evaluate a solution. Anything outside that intent window is a candidate for exclusion.

Do this weekly for any campaign with meaningful spend. Monthly is the absolute bare minimum. The longer you wait between audits, the more budget disappears into irrelevant search terms eating your budget that compound over time.

Step 2: Build and Apply Your Negative Keyword Lists

Once you've flagged the junk queries, it's time to actually block them. Negative keywords are the primary mechanism for telling Google "never show my ad for this search." Without them, Google will keep matching you to the same irrelevant queries week after week.

Before you start adding negatives, you need to understand how the three negative match types work—because they behave differently from positive match types in ways that trip people up.

Negative phrase match blocks your ad any time the search query contains that exact phrase, in that order. This is the workhorse for most situations. If you add "free" as a negative phrase match, your ad won't show for "free project management software," "free project management tools," or any other query containing the word "free."

Negative exact match only blocks queries that exactly match the term you specified, with no other words. Use this when you need surgical precision—for example, if you want to exclude a specific competitor name but still show up for searches like "[competitor name] alternative."

Negative broad match blocks queries that contain all the words in your negative keyword, in any order. One important note: unlike positive broad match, negative broad match does NOT include close variants. So if you add "plumbing school" as a negative broad match, it won't automatically block "plumbing schools" with an "s." You'd need to add both.

For most cases, negative phrase match is your best default. It's specific enough to avoid over-negating while broad enough to catch the variations you care about. If you're new to this process, our guide on how to add negative keywords in Google Ads walks through the mechanics step by step.

Now, where do you apply them? You have a few options:

Campaign-level negatives apply to all ad groups within that campaign. Good for terms that are universally irrelevant to everything in that campaign.

Ad group-level negatives apply only to that specific ad group. Useful when a term might be relevant in one ad group but not another—for example, if "enterprise" is relevant to your enterprise-tier ad group but not your SMB ad group.

Shared negative keyword lists can be applied across multiple campaigns at once. This is a huge time-saver for agencies managing multiple client accounts or advertisers running several campaigns with similar exclusions. Build a master list of universal negatives (like "free," "jobs," "salary," "how to") and apply it everywhere at once.

The common pitfall here is over-negating. It happens more than you'd think, especially when adding negatives in bulk. Before you mass-add a list of negatives, do a quick sanity check: run each term through the Search Terms Report and confirm it's genuinely irrelevant. Accidentally blocking a high-intent term because it shares a word with a junk query is a real mistake that costs conversions.

Step 3: Tighten Your Keyword Match Types

Negative keywords fix the symptoms. Match types address part of the root cause.

If you're running mostly broad match keywords without a strong negative keyword foundation, you're essentially handing Google the keys and hoping for the best. Broad match gives Google maximum freedom to interpret your keywords using contextual signals, audience data, and landing page content. Sometimes that works brilliantly. Often, it means you're showing up for searches that are tangentially related at best.

Here's a real-world example of what broad match can do: if you bid on broad match "project management software," Google might show your ad for "free project management templates," "project management degree online," or "project management certification cost." None of those are buyer queries. None of them are going to convert. But you're paying for every click.

The fix isn't necessarily to abandon broad match entirely. The approach depends on what you're trying to accomplish:

For high-spend, high-intent keywords: Consider shifting from broad match to phrase match or exact match. You'll see fewer impressions, but the traffic you do get will be far more relevant. After tightening match types on your top keywords, you should see CTR improve and cost-per-conversion decrease over the following weeks. Understanding how keyword match type affects your Google Ads performance is critical for making these decisions confidently.

For discovery and volume campaigns: Keep broad match, but pair it aggressively with negatives. Broad match is genuinely useful for finding new relevant search terms you haven't thought of yet. The key is treating it as a discovery tool, not a set-it-and-forget-it strategy. Review the Search Terms Report even more frequently for these campaigns.

One thing worth noting: Google retired broad match modifier back in 2021 and rolled that functionality into phrase match. So if you're working with older account structures that still reference BMM, those keywords are now behaving like phrase match. You can learn more about how phrase match changed in recent Google Ads updates to understand the full implications.

The trade-off with tighter match types is always reach versus relevance. Exact match gives you the most control but limits volume. Phrase match is usually the sweet spot for most campaigns. Find the right balance for each campaign based on its goals and available budget.

Step 4: Refine Audience and Location Targeting

Here's something that gets overlooked: irrelevant clicks don't only come from bad keyword matching. They also come from showing your ads to the wrong people in the wrong places.

Start with geographic targeting. Pull your location report (Campaigns > Locations) and sort by cost. Look for any locations with significant spend and zero or near-zero conversions. If you're a US-only B2B SaaS and you're getting clicks from countries you don't serve, that's pure waste. Exclude them. If you run local campaigns, understanding how negative keywords help in local Google Ads campaigns can dramatically reduce wasted spend in your area.

Even within your target country, geographic performance can vary significantly. Some regions might consistently underperform. You don't necessarily need to exclude them entirely, but bid adjustments can help you allocate budget toward the areas that actually convert.

Next, look at your audience segments. If you haven't already, add relevant audiences in observation mode. This lets you see how different audience segments are performing without restricting who sees your ads. Over time, you'll identify segments that click frequently but never convert—those are candidates for bid adjustments or exclusions.

What usually happens here is that you find a demographic or audience segment that looks plausible on paper but performs terribly in practice. Maybe your B2B software ads are getting a lot of clicks from students. Maybe your premium service is attracting budget-focused searchers who bounce immediately. The data will tell you.

Also check device performance. In some industries, mobile clicks have significantly lower conversion rates than desktop—not because mobile users aren't valuable, but because the conversion action (a long form, a phone call, a complex signup) doesn't translate well to mobile. Rather than excluding mobile entirely, consider a negative bid adjustment to reduce spend there while keeping some presence.

The goal of this step is to make sure that when someone does click your ad, they have a reasonable chance of being your actual customer. Keyword targeting gets you most of the way there. Audience and location targeting closes the gap.

Step 5: Set Up IP Exclusions and Click Fraud Protection

Some irrelevant clicks aren't coming from mismatched queries or wrong audiences. They're coming from bots, competitors clicking your ads out of spite, or the same person clicking your ad multiple times without any intention of converting.

Google does filter some invalid clicks automatically, and you can actually see how many in your Campaigns tab by modifying columns to show "Invalid clicks" and "Invalid click rate." Google's automated filtering catches a meaningful amount of fraudulent activity. But it doesn't catch everything, especially in competitive verticals where click fraud is more prevalent. If competitor click activity is a concern for your account, our guide on how to stop competitor clicks in Google Ads covers additional defensive strategies.

For IP exclusions, go to Settings > Additional Settings > IP Exclusions within each campaign. If you notice suspicious patterns—the same IP clicking multiple times in a short window, clicks coming from data center IP ranges, or spikes in clicks with no corresponding conversion activity—add those IPs to your exclusion list.

The limitation here is real: you can only exclude up to 500 IP addresses per campaign. That's enough for targeted exclusions, but it's not a comprehensive solution on its own. Think of IP exclusions as a surgical tool, not a complete defense strategy.

For larger accounts or industries where click fraud is a known problem, dedicated click fraud detection tools can automate this process. They monitor click patterns in real time and can automatically exclude suspicious IPs before significant damage is done. If you're spending heavily in a competitive vertical and your conversion rate seems inexplicably low, it's worth investigating whether your Google Ads clicks aren't converting due to fraudulent activity.

IP exclusions are a supplementary tactic. They're not a replacement for the keyword and audience work in the earlier steps. But for accounts dealing with suspicious activity, they're worth implementing.

Step 6: Automate and Streamline the Cleanup Process

Here's the honest truth about everything we've covered so far: it works. But doing it manually, across multiple campaigns or client accounts, is genuinely tedious. And when something is tedious, it doesn't get done consistently. That's how irrelevant clicks pile up in the first place.

The traditional manual workflow looks like this: export the Search Terms Report to a spreadsheet, filter and review hundreds of rows, copy the junk terms into another tab, format them correctly, go back into Google Ads, navigate to the negative keywords section, paste them in, apply to the right campaigns or ad groups, and repeat for every campaign. For one campaign, that might take 20-30 minutes. For an agency managing 10 client accounts, that's a significant chunk of your week—every week.

The biggest reason advertisers let irrelevant clicks pile up isn't laziness. It's that the process is slow enough that it gets deprioritized when things get busy. If you're managing more than a couple of campaigns, doing this manually every week isn't realistic long-term. Exploring how AI tools can help optimize your Google Ads campaigns is one way to reclaim that time.

This is exactly the problem that tools like Keywordme are built to solve. It's a Chrome extension that integrates directly into the Google Ads interface, so you're working right inside the Search Terms Report—no spreadsheets, no tab-switching, no exporting. You can remove junk search terms with a single click, bulk-add negative keywords, apply match types, and build keyword lists without ever leaving Google Ads.

For agencies managing multiple accounts, the time savings compound quickly. Instead of a 30-minute manual process per campaign, you're making decisions and taking action in real time as you review the report. Weekly search term audits become something you can actually sustain rather than something that keeps getting pushed to next week.

The success indicator for this step is simple: you can complete a full search term audit in a fraction of the time it used to take, which means you actually do it every week instead of every month. Consistency is what makes this process work over time.

Your Six-Step Checklist for Cleaner, More Efficient Campaigns

Let's pull it all together. Here's the repeatable process for removing irrelevant clicks from your Google Ads account:

1. Audit your Search Terms Report weekly. Sort by cost and clicks. Flag anything that doesn't match buyer intent: informational queries, wrong competitor names, geographic mismatches, unrelated terms.

2. Build and maintain negative keyword lists. Use negative phrase match as your default. Apply shared lists across campaigns for efficiency. Double-check before bulk-adding to avoid accidentally blocking relevant terms.

3. Tighten match types where appropriate. Shift high-spend keywords from broad to phrase or exact match. Keep broad match for discovery campaigns, but pair it aggressively with negatives and review frequently.

4. Refine audience and location targeting. Exclude non-converting geos. Use observation audiences to identify underperforming segments. Check device performance and apply bid adjustments where needed.

5. Exclude suspicious IPs and consider click fraud protection. Use IP exclusions for targeted suspicious activity. For high-spend accounts in competitive verticals, evaluate dedicated click fraud detection tools.

6. Use automation tools to make the process sustainable. If you're managing more than a handful of campaigns, manual workflows won't hold up. Find tools that let you act on search terms directly inside Google Ads.

Knowing how to remove irrelevant clicks in Google Ads isn't a one-time fix. It's an ongoing discipline. The advertisers who do this consistently—weekly audits, regular negative keyword maintenance, match type reviews—are the ones who see their cost-per-conversion trend down and their ROAS climb over time. The ones who skip it keep wondering why their budget never seems to go far enough.

The good news is that once you build the habit and have the right tools in place, it doesn't have to be a major time investment. It just has to happen regularly.
