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

Irrelevant clicks are one of the fastest ways to drain a Google Ads budget. Your ads show up for searches that have nothing to do with your product, someone clicks, and you pay—without any chance of a conversion. This happens to most advertisers running broad or phrase match keywords, and it tends to get worse as campaigns scale.

The good news is that it's fixable, and you don't need to overhaul your entire account to do it. This guide walks you through exactly how to find irrelevant search terms, block them with negative keywords, tighten your match types, and set up a review process that keeps junk traffic out going forward.

Before we dive in, one distinction worth keeping clear throughout: keywords are the terms you bid on inside Google Ads. Search terms are the actual queries users typed that triggered your ad. These are not the same thing, and the gap between them is often where irrelevant clicks live. Similarly, positive keywords are the ones you bid on to show ads, while negative keywords are the ones you add to prevent your ads from showing. Keeping these straight matters when you're building your exclusion strategy.

Whether you're managing one campaign or dozens, these steps work directly inside Google Ads. By the end, you'll have a clear system for protecting your budget and making sure your ads show up for searches that actually matter.

Step 1: Pull Your Search Terms Report and Identify the Problem

The Search Terms Report is where this process starts. Navigate to Campaigns > Search Terms in the Google Ads interface to see the actual queries that triggered your ads. This is different from your keyword list. Your keyword list shows what you're bidding on; the Search Terms Report shows what users actually typed before your ad appeared.

Once you're in the report, sort by cost or clicks to surface the highest-spend queries first. You want to prioritize the terms that are costing you the most before worrying about low-traffic outliers. A search term that triggered three clicks at $0.40 each is a rounding error. A search term that triggered 80 clicks at $3.50 each and generated zero conversions is a real problem.

Use a date range of at least 30 days. Shorter windows can miss patterns, especially for campaigns that don't have high daily volume. A 30-to-90-day window gives you a statistically meaningful sample to work with.

As you scan through the report, look for these red flags:

Competitor brand names: If users are searching for a competitor and your ad is appearing, you're paying for clicks from people who already have a brand preference that isn't yours.

Free or low-cost modifiers: Queries containing "free," "cheap," "DIY," or "how to do it yourself" signal users who aren't looking to buy. If you're selling a paid service or product, these clicks rarely convert.

Job seekers and students: Searches like "internship," "course," "certification," or "how to become a [role]" are research queries from people at the beginning of a learning journey, not buyers.

Wrong geography: If your service is location-specific, look for searches that include place names outside your area.

Unrelated industries or use cases: Sometimes a keyword you bid on has multiple meanings across different industries. If you're bidding on a term that's also used in an unrelated field, you'll see it in the search terms data.

You know this step is done when you can clearly identify at least five to ten search terms that triggered your ads but would never lead to a conversion. That list becomes the foundation for everything that follows.

Step 2: Categorize Irrelevant Traffic Before You Act

Before you start adding negative keywords one by one, group your problem search terms into categories. This step takes an extra few minutes but makes the entire process faster and more systematic. It also prevents you from playing whack-a-mole with individual queries while the broader pattern keeps generating new junk traffic.

Here are the most common categories you'll encounter:

Informational and research queries: These include searches starting with "what is," "how does," "what are," or "explain." The user is in research mode, not buying mode. If your product requires purchase intent to convert, these clicks are wasted spend.

Free-intent queries: Anything with "free," "cheap," "no cost," "open source," or "DIY" attached to your core keyword. Users adding these modifiers are explicitly signaling they don't want to pay. If you're selling a paid product, this is a clear mismatch. For more on this specific pattern, see our guide on why your ads are showing for free searches.

Wrong-audience queries: Job seekers searching for roles in your industry, students looking for coursework, or researchers gathering information. These users aren't buyers. We cover the student traffic pattern specifically in our article on why students are clicking your ads, and the DIY traffic pattern in our piece on why you're getting DIY traffic from Google Ads.

Competitor brand terms: Searches that include a competitor's brand name. These deserve a separate flag because the right response isn't always a simple negative. Sometimes a dedicated competitor campaign with tailored messaging makes more sense than blocking the traffic entirely. Identify these and decide separately.

Unrelated product categories: Queries where a word in your keyword has a different meaning in another context. Your ads are appearing for searches in a completely different industry or use case.

Once you've grouped your terms, note which categories are costing the most. Prioritize those first. You don't need to solve every category at once—focus on where the budget is going and work from there.

You know this step is done when your problem terms are organized into three to five clear buckets, each with a clear action assigned to it. That structure makes the next step significantly faster.

Step 3: Build Your Negative Keyword List

Now you're ready to add negative keywords. A few decisions to make before you start adding them.

Campaign level vs. ad group level: Campaign-level negatives apply to every ad group within that campaign. Ad group-level negatives are more surgical and only block traffic at that specific ad group. Use campaign-level negatives for exclusions that apply broadly across your whole campaign. Use ad group-level negatives when only one ad group is generating the irrelevant traffic and you don't want to restrict other ad groups unnecessarily.

Choosing the right negative match type: Negative match types work differently from positive match types, so it's worth being precise here.

Negative broad match blocks queries that contain any of the words in your negative keyword, in any order. It's the widest net. Use it carefully because it can catch legitimate queries you didn't intend to block.

Negative phrase match blocks queries that contain your negative keyword phrase in that specific order. This is the most practical starting point for most junk categories. It's wide enough to catch variations without being as aggressive as negative broad.

Negative exact match blocks only that precise query. This is the right choice for competitor brand terms where you want precision and don't want to accidentally block related queries that might be relevant.

For most of the categories you identified in Step 2, start with negative phrase match. For competitor brand names, use negative exact match. Avoid negative broad match unless you've tested it and are confident it won't block high-intent queries.

Before adding any negative, do a quick sanity check: would this negative also block a search term that's currently converting? You can check this by searching for the term in your Search Terms Report. Over-blocking is a real risk, especially with negative phrase and negative broad.

If you manage multiple campaigns with the same exclusions, use a shared negative keyword list. You build the list once and apply it across multiple campaigns. This saves time and keeps your exclusions consistent. For more on when to use shared lists versus campaign-specific negatives, see our breakdown of the difference between shared and campaign-specific negative keyword lists.

If you're doing this work inside Google Ads, Keywordme's Chrome extension lets you add negative keywords directly from the Search Terms Report with one click. You don't need to export anything to a spreadsheet or switch tabs. You review the search term, click to add it as a negative, choose your match type, and move on. It's a straightforward way to speed up a task that can otherwise take a lot of manual effort.

You know this step is done when your negatives are added at the correct level and match type, and you've verified that none of them would block search terms that are currently driving conversions.

Step 4: Audit and Tighten Your Match Types

Negative keywords fix the symptom. Match types address part of the cause. If your campaigns are running broad match keywords without comprehensive negatives protecting them, irrelevant search terms will keep appearing no matter how many negatives you add.

Google's broad match has expanded its semantic matching behavior over time. Broad match keywords can now trigger ads for queries that are loosely related or semantically similar to your keyword, not just queries that contain your keyword's words. This gives Google more flexibility to find traffic, but it also means your ads can appear for searches that are a significant stretch from what you intended. For a closer look at this pattern, our article on why broad match wastes money covers the mechanics in detail.

Here's how to approach the audit:

Identify your broad match keywords: Filter your keyword list by match type. Look at which broad match keywords are generating the most irrelevant search terms in your Search Terms Report. These are your highest-priority candidates for either adding more negatives or switching to a tighter match type.

Consider phrase match as a middle ground: Phrase match still gives Google some flexibility, but it constrains the query to include your keyword phrase in the right order. It's a reasonable step between broad and exact for keywords where you want reach but also more control.

Use exact match for your proven converters: Exact match gives the tightest control over which queries trigger your ads. It limits reach, so it's best reserved for keywords that have a clear track record of converting. You're trading volume for precision.

Don't overhaul everything at once: Switching all your broad match keywords to exact match overnight can cause a significant drop in traffic and impressions. Make changes gradually. Shift one or two high-spend broad match keywords to phrase match, monitor for a week or two, then continue. Abrupt changes make it harder to isolate what caused any performance shifts.

Running a mix of match types with proper negatives is a common and effective strategy. You don't have to pick one. Broad match with a strong negative list can work well for discovery and volume. Exact match works well for your core high-intent terms. The goal is intentional coverage, not a uniform approach. For more on when each match type makes sense, see our guide on when to use broad match versus exact match.

You know this step is done when your broad match keywords either have comprehensive negatives protecting them or have been migrated to a tighter match type based on performance data.

Step 5: Apply Audience and Location Filters to Cut Out the Wrong Visitors

Negative keywords filter at the query level. But sometimes the issue isn't what someone searched—it's who they are or where they are. That's where audience exclusions and location targeting come in.

Audience exclusions: In Google Ads, you can exclude specific audiences from seeing your ads at the campaign or ad group level. If your product clearly doesn't serve a particular group—students, for example, or a specific age bracket—you can exclude them from your targeting. This prevents your ads from showing to those users regardless of what they search.

Before committing to exclusions, use audience observation first. Observation mode lets you collect data on how different audience segments are performing without restricting who sees your ads. Once you have enough data to see that a specific segment is clicking frequently but not converting, you can move from observation to exclusion with confidence rather than guessing.

Demographic targeting: Google Ads lets you apply bid adjustments or exclusions based on age, gender, household income, and parental status. If your product or service clearly doesn't serve certain demographic groups, check your demographic reports. Look for segments with high click volume and low or zero conversions. You can reduce bids for those segments or exclude them entirely if the data supports it.

Location targeting: If irrelevant clicks are coming from outside your service area, check your location settings. Google Ads has two options that matter here: "Presence or interest" shows your ads to people who are in your targeted location or who have shown interest in it. "Presence or regular presence" shows your ads only to people who are actually in your targeted location. If you're getting clicks from outside your service area, switching to "Presence or regular presence" is a straightforward fix.

Device bid adjustments: If your Search Terms Report shows that mobile traffic is generating a disproportionate share of irrelevant clicks with poor conversion rates, consider reducing your mobile bid adjustment rather than excluding mobile entirely. A bid reduction lets you stay in the auction at a lower cost rather than going dark on that device type.

You know this step is done when you've reviewed your demographic, audience, and location reports and applied exclusions or bid adjustments where the data clearly supports it.

Step 6: Schedule a Weekly Search Terms Review

Everything you've done in the previous five steps is valuable. But it's not a one-time fix. Google continuously expands match behavior, search trends shift, and new irrelevant queries appear in your Search Terms Report on a regular basis. Without an ongoing review process, junk traffic will creep back in.

The fix is simple: put a recurring calendar reminder in place. A weekly or bi-weekly review of the Search Terms Report is enough to stay on top of new problems before they accumulate into significant wasted spend.

Here's what a standard review session looks like:

1. Filter the Search Terms Report for the past 7 to 14 days to focus on new queries you haven't reviewed before.

2. Scan for new irrelevant search terms using the same categories you built in Step 2. New junk queries often follow the same patterns—free-intent, wrong audience, unrelated industry.

3. Add new negative keywords at the appropriate level and match type. Don't let them sit. The sooner you add a negative, the sooner it starts protecting your budget.

4. Flag any new high-intent search terms that look like they should be added as positive keywords. The Search Terms Report isn't just for finding problems—it's also a source of keyword expansion opportunities.

Keep a running negative keyword master list outside your account. A simple document or shared sheet works. This gives you a reference point to spot patterns across campaigns and apply learnings quickly when you set up new campaigns in the future.

For agencies managing multiple accounts, prioritize high-spend accounts for weekly review and lower-spend accounts for monthly review. The frequency should match the volume of traffic and the cost of letting junk queries run unchecked.

Keywordme's one-click actions and bulk editing inside the Search Terms Report make this weekly routine significantly faster. You can process a large list of search terms without leaving the Google Ads interface, which removes most of the friction that makes people skip the review. When the task is quick, it actually gets done.

You know this step is done when you have a scheduled review cadence and a clear process for acting on new junk search terms within seven days of them appearing.

Your Irrelevant Click Elimination Checklist

These six steps form a complete system for eliminating irrelevant clicks in Google Ads. Not a one-time cleanup, but an ongoing process that keeps your budget pointed at searches that can actually convert.

Here's a quick checklist to confirm you've covered the ground:

Search Terms Report pulled and reviewed — You've identified at least five to ten search terms that triggered your ads but would never convert.

Irrelevant terms categorized — Your problem queries are grouped into clear buckets with a defined action for each.

Negative keywords added at the correct level and match type — Campaign or ad group level, phrase or exact match where appropriate, and no high-intent terms accidentally blocked.

Match types audited and tightened where needed — Broad match keywords either have comprehensive negatives or have been migrated to phrase or exact match based on performance data.

Audience, demographic, and location exclusions applied — Based on actual data from your reports, not guesswork.

Weekly review routine scheduled — A recurring calendar reminder is in place and you have a process for acting on new junk terms within seven days.

The biggest gains usually come from the first three steps. Don't wait to have everything perfect before acting. Pull the report, categorize the problems, add the negatives. The rest can follow.
