How to Remove Irrelevant Search Terms in Google Ads (Step-by-Step)

You bid on a keyword. Google matches your ad to a search term. Those two things are not always the same — and that gap is where budget quietly disappears.

If you've ever opened your Search Terms Report and spotted queries like "free [your service]", "[your industry] jobs", or something that has nothing to do with what you sell, you've already seen this problem firsthand. Google's matching algorithms are designed to find reach, not precision. That's useful in some contexts, but it means your ads can show for searches that will never convert, and you pay for every click regardless.

To be clear on terms before we go further: a keyword is what you bid on — the target you set inside Google Ads. A search term is the actual query a user typed that caused your ad to appear. These are related but distinct. A negative keyword is an exclusion you add to stop your ads from showing for specific queries. Keeping these three concepts separate matters throughout this guide.

By the end of this walkthrough, you'll know how to find the search terms draining your budget, how to exclude them correctly using negative keywords, how to organize those exclusions for long-term efficiency, and how to build a review habit that keeps wasted spend from creeping back in. This is one of the highest-ROI maintenance tasks in Google Ads because it reduces waste without requiring you to increase your budget.

Let's get into it.

Step 1: Understand Why Irrelevant Search Terms Appear

Before you start excluding anything, it helps to understand why irrelevant search terms show up in the first place. The short answer: match types.

When you add a keyword to a campaign, you're not telling Google to match your ad only to that exact phrase. Depending on the match type you've selected, you're giving Google varying degrees of freedom to interpret what counts as "related enough."

Broad match is the most expansive. Google can show your ad for queries it considers semantically related to your keyword, even if those queries share no words with it. A keyword like "project management software" on broad match might trigger searches for "team collaboration tools", "how to organize work tasks", or in some cases, queries further afield than you'd expect.

Phrase match is more controlled, but still allows Google to match your ad to queries that include the meaning of your keyword phrase, with words added before or after. The interpretation has loosened over the years, so phrase match today covers more ground than it once did.

Exact match feels like it should be airtight, but Google also applies close variant matching here. That means your exact match keyword can trigger ads for queries with the same meaning, including paraphrases, implied words, or reordered terms. Most of the time this is fine, but it can surface variants that don't fit your specific offer.

The practical upshot: the broader your match types, the wider the gap between what you intended to target and what actually triggers your ads. Irrelevant search terms are a natural byproduct of how Google's matching system works, not a sign that something is broken. The fix is a combination of better match type choices and consistent negative keyword management — and this guide focuses on the latter.

If you want to go deeper on match type behavior, it's worth reading up on when broad match makes sense versus when exact match is the safer choice. Understanding that context helps you make better exclusion decisions in the steps ahead.

Once you understand why the problem exists, you're ready to look at the data.

Step 2: Open the Search Terms Report in Google Ads

The Search Terms Report is where you see every query (that Google is willing to show you) that triggered your ads during a selected time period. Here's how to get there.

In most Google Ads accounts, navigate to Campaigns in the left-hand menu, then select Keywords, then click Search Terms. In some account configurations, you may find it under Insights & Reports instead. Google periodically updates the interface, so if the path looks slightly different in your account, look for "Search Terms" in the navigation sidebar or use the search bar at the top of the interface.

Once you're in the report, the first thing to do is set a meaningful date range. A single week of data is rarely enough to make confident exclusion decisions — you might flag a term based on one or two clicks that would look completely different over a longer window. Set your date range to at least 30 days. For campaigns with moderate spend, 60 to 90 days gives you a more representative picture of which terms are consistently problematic versus which appeared once and haven't returned.

Next, look at the columns that matter most for identifying waste:

Impressions: How often your ad appeared for this search term. High impressions with low clicks can indicate poor relevance.

Clicks: How many times someone clicked your ad after searching this term. Clicks cost money, so this is where waste becomes real.

Cost: The total spend attributed to this search term. Sort by this column descending to find the most expensive terms first.

Conversions: Whether any clicks from this term resulted in a conversion. A term with significant spend and zero conversions over a long period is worth scrutinizing.

Conversion Value: If you're tracking revenue or lead value, this tells you whether the term is contributing anything meaningful to business outcomes.

One important caveat: Google does not show all search terms. Queries that fall below certain volume thresholds are withheld for privacy reasons. This is documented Google behavior, not a reporting error. It means your report is a useful but incomplete picture — you're seeing the terms that occurred frequently enough to surface, not every query that ever triggered your ad.

Don't make exclusion decisions based on a single click or a few dollars of spend. Look for patterns across meaningful data. A term that has spent a noticeable amount with zero conversions over 60 days is a strong candidate. A term that appeared twice last month is not worth acting on yet.

With the report open and filtered to a useful date range, you're ready to start identifying what actually needs to go.

Step 3: Identify Which Search Terms Are Actually Irrelevant

Not every underperforming search term is irrelevant. This distinction matters because the fix for each is different, and conflating them leads to bad exclusion decisions.

An irrelevant search term comes from someone who would never buy what you're selling, regardless of your ad copy, landing page, or offer. The intent behind the query is fundamentally mismatched with your business.

A low-performing search term might come from someone who could be a legitimate customer, but something in your funnel — the ad message, the landing page, the offer — isn't connecting. That's a conversion rate problem, not a targeting problem, and excluding it won't fix the underlying issue.

For this step, focus only on the first category: terms where the intent is clearly wrong.

A simple mental filter helps here. Ask yourself: "Would someone who typed this query ever realistically buy from us?" If the answer is no, it's irrelevant. If the answer is "probably not, but maybe," that's a judgment call worth revisiting with more data.

Here are the most common patterns of irrelevant search terms that appear across Google Ads accounts:

Job seeker queries: Terms like "[your industry] jobs", "[your service] salary", "[your product] careers", or "[brand] hiring" indicate someone looking for employment, not your product or service. These are especially common for businesses in industries where the job title and the service share similar keywords.

Free or DIY intent: Queries containing "free", "DIY", "how to do it yourself", or "without paying" typically signal someone who is not in a buying mindset. If you sell a professional service or paid software, these clicks are unlikely to convert.

Informational research queries: Terms like "what is [your product category]", "how does [your service] work", or "definition of [industry term]" often come from people at the very beginning of their research, not ready to purchase. These can be worth excluding from transactional campaigns, though they may be appropriate for awareness-stage campaigns if you run them.

Student and academic queries: Searches with words like "essay", "assignment", "course", "study", "exam", or "school project" attached to your keywords usually indicate students doing research, not buyers.

Competitor brand names you're not targeting: If your ad is appearing for a competitor's brand name and you haven't intentionally set up competitor targeting, that's often wasted spend — especially if the searcher has strong brand loyalty to that competitor.

Sort your Search Terms Report by Cost descending before you start flagging. This ensures you're prioritizing the terms that have already cost you the most, rather than spending time on low-spend outliers that have minimal budget impact.

Work through the list and build a shortlist of confirmed irrelevant terms. Be deliberate — only flag terms where you're confident the intent is wrong. When in doubt, leave it for now and revisit with more data.

With your shortlist ready, the next step is turning those terms into negative keywords.

Step 4: Add Irrelevant Terms as Negative Keywords

Once you've identified which search terms don't belong, you need to exclude them. In Google Ads, exclusions are added as negative keywords. Here's how to do it correctly.

Where to Add Negative Keywords

Negative keywords can be applied at two levels within a campaign structure:

Campaign level: The negative keyword blocks the search term across all ad groups within that campaign. Use this when a term is irrelevant to your entire campaign, not just one ad group.

Ad group level: The negative keyword blocks the search term only within a specific ad group. Use this for more surgical exclusions — for example, if a term is irrelevant to one product line but potentially relevant to another within the same campaign.

There's also a third option: shared negative keyword lists, which live in the Shared Library and can be applied across multiple campaigns. More on that in Step 5.

The Native Google Ads Process

In the Search Terms Report, check the box next to each term you want to exclude. Then click Add as negative keyword in the toolbar that appears. A panel will open asking you to choose where to add the negative keyword (ad group, campaign, or a negative keyword list) and which match type to apply.

Choosing the Right Negative Match Type

Negative match types behave differently from positive match types, and the distinction matters.

Negative broad match blocks any query that contains the specified word or phrase, in any order, anywhere in the query. This is the most aggressive option. If you add "free" as a negative broad match keyword, your ads won't show for any query containing the word "free" — including "free trial", "free consultation", "best free tool", and so on. Use this for clearly irrelevant single words where you're confident you don't want any query containing that word.

Negative phrase match blocks queries that contain your negative keyword phrase in the same order, but allows additional words before or after. This gives you more control than negative broad match when you want to block a specific phrase but not every query containing individual words from it.

Negative exact match blocks only the precise query, with no additional words. Use this when a specific term is irrelevant but individual words within it might appear in legitimate searches you want to keep.

In practice: for single irrelevant words like "free", "jobs", "DIY", or "salary", negative broad match is usually the right call. For longer irrelevant phrases where individual words might appear in relevant queries, negative phrase or exact match gives you more precision.

Watch Out for Over-Blocking

The most common mistake when adding negative keywords is being too aggressive. Adding a negative broad match keyword for a common word can accidentally block relevant traffic you didn't intend to exclude. Before confirming, think through whether the word or phrase appears in any queries you actually want to capture.

If you're managing multiple campaigns and want to apply exclusions efficiently, adding to a shared negative keyword list (rather than campaign-by-campaign) saves time and keeps your exclusions consistent. This is covered in the next step.

If you're using Keywordme, this process is faster. You can select irrelevant search terms directly in the Search Terms Report and add them as negatives with a single click, without exporting to a spreadsheet or navigating to a separate screen. For anyone reviewing large volumes of terms across multiple campaigns, that reduction in friction adds up quickly.

Once your irrelevant terms are saved as negative keywords at the right level and match type, you've completed the core fix. The next two steps are about making sure it stays fixed.

Step 5: Organize Your Negative Keywords Into Reusable Lists

Adding negative keywords one campaign at a time works, but it doesn't scale well. If you manage multiple campaigns or multiple client accounts, the same irrelevant terms tend to appear everywhere. Shared negative keyword lists solve this.

A negative keyword list is created once in the Shared Library and can be applied to as many campaigns as you want. When you update the list, the change applies across every campaign it's attached to — no need to make the same edit in multiple places.

How to Create a Negative Keyword List

In Google Ads, go to Tools & Settings (the wrench icon), then Shared Library, then Negative Keyword Lists. Create a new list, give it a clear name, add your negative keywords, and then apply the list to the relevant campaigns.

Suggested List Categories

Rather than dumping every excluded term into one list, organize them by intent type. This makes future audits much easier.

Intent filter list: Terms signaling non-buyer intent — free, DIY, how-to, download, tutorial, course, certification. These apply broadly across most transactional campaigns.

Job seeker filter list: Terms like jobs, salary, careers, hiring, internship, resume. Again, broadly applicable if you're running product or service campaigns.

Brand protection list: Competitor brand names you don't want to serve, or your own brand terms if you're excluding them from non-brand campaigns for budget control reasons.

Audience filter list: Terms specific to your industry that signal the wrong buyer profile — these will vary depending on what you sell.

Give each list a descriptive name that makes its purpose obvious to anyone who might look at the account later, including teammates or clients. A list named "Intent Filter — Non-Buyer Terms" is far more useful than "Negative List 3".

One thing to avoid: a single massive list containing hundreds of unrelated terms. It becomes difficult to audit, easy to over-apply, and hard to maintain over time. Smaller, purpose-built lists are easier to manage and less likely to cause accidental blocking.

With your exclusions organized into reusable lists, the last step is making sure this doesn't become a one-time cleanup that slowly unravels.

Step 6: Build a Regular Search Term Review Cadence

Removing irrelevant search terms once is useful. Doing it consistently is what actually controls wasted spend over time.

Google's matching behavior evolves. New search trends emerge. Campaign changes — new keywords, new ad groups, budget increases, match type adjustments — can introduce fresh irrelevant traffic. A search term review is not a one-time fix; it's an ongoing maintenance task.

How Often Should You Review?

A practical guideline: for campaigns with significant daily spend, review weekly. For smaller budgets, bi-weekly or monthly is usually sufficient. The goal is to catch new irrelevant terms before they accumulate meaningful spend, not to do a perfect audit every time.

A Simple Review Checklist

1. Open the Search Terms Report and set the date range to cover the period since your last review.

2. Sort by Cost descending to surface the most expensive terms first.

3. Scan for new irrelevant terms using the same mental filter from Step 3: "Would someone who typed this ever buy from us?"

4. Flag confirmed irrelevant terms and add them to the appropriate negative keyword list.

5. Note the review date so you know where to start next time.

That's the full loop. It doesn't need to be complicated. Consistency matters more than thoroughness — a quick 15-minute review every week beats a quarterly deep-dive that lets months of wasted spend accumulate in between.

Set a recurring calendar reminder for your review. It sounds obvious, but without a scheduled prompt, this task tends to get deprioritized when other work picks up.

For teams managing multiple accounts, the friction of switching between tools and exporting data can make this review feel heavier than it needs to be. Keywordme's in-interface workflow lets you complete the review directly inside Google Ads without leaving the platform or opening a spreadsheet, which makes it more realistic to maintain a consistent cadence across multiple clients.

Negative keyword management and ongoing search term hygiene are among the most consistently recommended practices in PPC for good reason: the cost of ignoring them compounds over time, and the benefit of maintaining them is direct and measurable.

Your Search Term Hygiene Checklist

Here's a quick-reference summary of everything covered in this guide — bookmark it and use it as your review checklist going forward.

1. Understand the source of the problem. Irrelevant search terms appear because match types give Google latitude to interpret your keywords broadly. Knowing this helps you make smarter exclusion decisions.

2. Open the Search Terms Report. Navigate to Campaigns > Keywords > Search Terms. Set your date range to at least 30 days. Focus on Impressions, Clicks, Cost, and Conversions.

3. Identify genuinely irrelevant terms. Sort by Cost descending. Flag terms where the intent is clearly wrong — job seekers, free/DIY queries, informational research, academic searches. Don't confuse irrelevant terms with low-performing ones.

4. Add exclusions as negative keywords. Choose the right level (ad group, campaign, or shared list) and the right match type (negative broad for single irrelevant words, negative phrase or exact for longer phrases). Avoid over-blocking.

5. Organize negatives into reusable lists. Create purpose-built lists in the Shared Library — intent filter, job seeker filter, brand protection, audience filter. Apply them across campaigns.

6. Review on a regular cadence. Weekly for high-spend campaigns, monthly for smaller budgets. Set a calendar reminder and stick to it.

Removing irrelevant search terms is one of the most direct ways to reduce wasted spend in Google Ads without touching your budget. The work compounds: the cleaner your account, the more efficiently your budget reaches people who are actually likely to convert.
