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

If you're running Google Ads, irrelevant search terms are quietly draining your budget every single day. Your ads are showing up for searches that have nothing to do with what you sell, and you're paying for those clicks. The problem isn't your bids or your ad copy. It's that Google's matching behavior, especially with broad and phrase match keywords, casts a wide net. Some of what it catches is gold. A lot of it isn't.

This guide walks you through exactly how to find those irrelevant search terms, evaluate them, and remove them from your campaigns without breaking what's already working. You'll also learn how to build a negative keyword strategy that keeps your account cleaner over time, so you're not doing this same cleanup every few weeks.

Before we get into the steps, one distinction matters throughout this entire guide: keywords are the terms you bid on in Google Ads. Search terms are the actual queries users typed that triggered your ad. These are not the same thing, and the Search Terms Report is where you see the real picture. Positive keywords are the ones you're actively bidding on. Negative keywords are the ones you explicitly exclude from triggering your ads.

Keeping those four terms straight will make every step below clearer and help you avoid the most common mistakes practitioners make when cleaning up their accounts.

Whether you're managing one campaign or twenty, the process is the same. It just gets faster with the right workflow. By the end of this guide, you'll know how to audit your search terms report, identify the queries wasting your spend, add them as negative keywords at the right level, and set up a repeatable review process. Let's get into it.

Step 1: Pull Up Your Search Terms Report

The first thing to understand is where to look. A lot of advertisers spend time in the Keywords tab, which shows the keywords they're bidding on. That's not where you find irrelevant search terms. You need the Search Terms Report, which shows you what users actually typed before your ad appeared.

To get there in Google Ads, navigate to Campaigns, select the campaign you want to audit, then click Search terms in the left-hand menu. You can also access a top-level view across campaigns from the main navigation. The path may vary slightly depending on your account layout, but the Search Terms section is distinct from the Keywords section. If you're looking at keyword-level data, you're in the wrong place.

Once you're in the report, set a meaningful date range. A single week of data is rarely enough to make good decisions. Aim for at least 30 days, and ideally 60 to 90 days if your campaign has been running long enough. A longer window gives you enough impressions and clicks to see patterns rather than noise. A search term that looks irrelevant with three impressions might look different with 300.

Next, use the available filters to surface the terms that matter most. Sorting by cost (descending) immediately shows you where your budget is going. You can also filter by impressions, clicks, or conversions depending on what you're trying to evaluate. If you want to find terms that are costing you money without producing results, sort by cost and look at conversion data side by side.

One common mistake at this stage is working with too short a date range and making exclusion decisions on thin data. A term with two clicks and no conversion isn't necessarily a problem. A term with 80 clicks, meaningful spend, and zero conversions over 60 days is a much clearer signal. Let the data tell you something before you act on it.

The Search Terms Report is your starting point for everything that follows. Get comfortable navigating it before moving to the next step.

Step 2: Identify Which Search Terms Are Actually Irrelevant

Not every search term without a conversion is irrelevant. That's an important distinction, and skipping it leads to over-exclusion, which can quietly reduce the reach of campaigns that were actually working. The goal here is to identify terms that are genuinely off-target, not just terms that haven't converted yet.

Start by sorting your Search Terms Report by cost, descending. Your most expensive terms appear at the top. For each one, ask a simple question: does this query match what someone would type if they were looking for what I sell? If the answer is clearly no, it's a candidate for exclusion. If you're unsure, keep reading before deciding.

There are a few categories of irrelevant search terms worth looking for specifically.

Intent mismatch: These are informational queries triggering ads meant for transactional audiences. If you're running a campaign for a paid software product and your ad is showing for "what is [category]" or "how does [category] work," those users are in research mode, not buying mode. They're unlikely to convert, and you're paying for the click.

Off-topic modifiers: Broad match keywords in particular can match to queries with modifiers that change the meaning entirely. A keyword like "project management tool" might trigger for "free project management tool" or "DIY project management spreadsheet." Neither of those searchers is looking for what you sell.

Brand mismatches: Your ads might be showing for competitor names, especially if you're using broad match. Whether that's intentional depends on your strategy. If it's not intentional, those terms are worth reviewing.

Job-seeker queries: Terms like "jobs," "careers," "salary," or "how to become" are a common source of wasted spend for B2B and SaaS advertisers. Someone searching for a job in your industry is not looking to buy your product.

Here's where judgment matters: a term with one click and no conversion is not automatically irrelevant. Check whether the query is topically related to your offer. If it is, give it more time before excluding it. If it's clearly off-topic regardless of conversion data, add it to your exclusion list. The distinction between "hasn't converted yet" and "will never convert" is what separates a careful negative keyword strategy from one that slowly chokes your own campaigns.

Step 3: Decide Where to Add Your Negative Keywords

Once you've identified terms you want to exclude, the next decision is where to add them. This step trips up a lot of advertisers, and getting it wrong can either leave gaps in your exclusions or accidentally block traffic you actually wanted.

There are two main levels to understand.

Campaign-level negatives apply only to the campaign where you add them. If a search term is irrelevant to one specific product or audience but might be relevant to another campaign in your account, campaign-level is the right choice. It keeps the exclusion scoped without affecting everything else.

Shared negative keyword lists are managed under Tools and Settings, then Shared Library, then Negative keyword lists. Once you create a list, you can apply it to multiple campaigns at once. Any updates to the list automatically apply across all campaigns using it. This is the right approach for terms that should never trigger any of your ads, regardless of campaign.

Common candidates for shared lists include terms like "free," "DIY," "tutorial," "jobs," "salary," and competitor names you universally exclude. These are terms that indicate the wrong intent across the board, not just for one campaign.

The most common mistake at this stage is adding a negative at the wrong level. Adding a competitor name as a campaign-level negative when you meant to exclude it everywhere means you'll need to add it again for each new campaign you create. Conversely, adding something to a shared list that only applies to one product line might block relevant traffic in other campaigns.

Take a moment before adding each negative to ask: is this irrelevant everywhere, or just here? That single question will keep your account structure clean. For a deeper look at how these two approaches differ, this explainer on shared versus campaign-specific negative keyword lists breaks it down clearly.

Step 4: Add Negative Keywords With the Right Match Type

Match types for negative keywords work differently from match types for positive keywords, and this is one of the most misunderstood areas in PPC. Getting this right means your exclusions actually do what you intend.

Here's how the three negative match types behave.

Negative broad match blocks any query that contains the excluded word, in any order and in combination with other words. This is the widest exclusion. Use it carefully, because a single word added as a negative broad match can block a surprising amount of traffic. For example, adding "free" as a negative broad match will block queries like "free trial software," "best free tools," and "free download," which may or may not be what you want.

Negative phrase match blocks queries that contain the exact phrase in that order, even if other words appear before or after it. This is more precise and is generally the safest default for most exclusions. If you add "free trial" as a negative phrase match, it blocks "best free trial software" but not "software with a free tier," since the phrase "free trial" doesn't appear in that order in the second query.

Negative exact match blocks only that specific query and nothing else. It's the most surgical option, useful when you want to exclude one very specific search without affecting anything adjacent to it.

Most practitioners default to negative phrase match for both single-word and multi-word exclusions. It provides a good balance between coverage and precision without the risk of over-blocking that comes with negative broad match.

To add negative keywords directly from the Search Terms Report in Google Ads, select the terms you want to exclude using the checkboxes, then click Add as negative keyword. You'll be prompted to choose the level (campaign or ad group) and the match type before confirming. Review both choices before saving.

If you're managing a busy account and want to skip the export-and-spreadsheet routine, Keywordme lets you do this directly inside the Search Terms Report with a single click. You select the terms, choose your match type and level, and they're added without leaving the native Google Ads interface.

Step 5: Build a Reusable Negative Keyword List

Adding individual negatives one at a time gets the job done, but it doesn't scale. If you're managing multiple campaigns or onboarding new ones regularly, building a structured shared negative keyword list is what separates a reactive cleanup from a proactive system.

The idea is simple: instead of re-adding the same obvious exclusions every time you launch a campaign, you maintain a master list that you can apply instantly. Every new campaign gets cleaner from day one.

Here are the categories worth including in a reusable list.

Irrelevant intent modifiers: Words like "free," "DIY," "cheap," "tutorial," "how to," and "what is" often signal informational or non-commercial intent. Include them if they consistently attract the wrong audience for your offer.

Job-seeker terms: "Jobs," "careers," "salary," "internship," and "how to become" are common culprits for B2B and SaaS advertisers. Add them early and save yourself the cleanup later.

Off-topic industries: If your keyword could apply to a completely different industry, add the industry-specific terms that trigger those irrelevant queries. A software company bidding on "pipeline" might pick up queries about plumbing or oil pipelines. Those terms belong on the exclusion list.

Competitor names (if applicable): If you're not running a competitor-targeting strategy, add competitor brand names to your shared list so they don't trigger your ads accidentally through broad match.

Save your list in Google Ads under Tools and Settings, then Shared Library, then Negative keyword lists. Give it a clear name and document why terms were added, either in a connected spreadsheet or in a notes field your team can access. Future you, or a teammate picking up the account, will thank you for the context.

For agencies managing multiple client accounts, Keywordme's bulk editing and multi-account support makes maintaining these lists significantly faster. You can manage shared negatives across accounts without jumping between tabs or exporting data.

Step 6: Set a Regular Search Terms Review Schedule

Here's the part most guides skip: a one-time cleanup isn't enough. Google's matching behavior evolves, your campaigns expand, and new irrelevant search terms appear over time. If you don't review your Search Terms Report regularly, the problem you just fixed will quietly come back.

The right cadence depends on your spend level. For active campaigns with meaningful daily budgets, a weekly review is worth building into your routine. For smaller campaigns with lower spend, bi-weekly is usually sufficient. The goal is to catch expensive irrelevant terms before they accumulate significant wasted spend, not after.

Each review session should cover three things.

1. New high-spend terms with no conversions: Sort by cost, look at the date range since your last review, and flag any terms that have spent meaningfully without converting. Apply the same judgment from Step 2 before adding them as negatives.

2. New intent mismatches: As your campaigns evolve and Google's matching shifts, new off-topic queries will appear. Check for informational queries, off-topic modifiers, and anything that doesn't match your current targeting intent.

3. Terms that have since converted: This one gets overlooked. If a search term you were considering excluding has since produced a conversion, it might actually belong in your positive keyword list. Review before excluding, and consider adding high-performing terms as positive keywords with a more precise match type to give them better control.

The easiest way to make this a habit is to tie it to your existing reporting schedule. If you pull a weekly performance report on Mondays, add the Search Terms review to that same session. It takes less time once you have a structured process, and the account gets cleaner with each pass.

The goal isn't to achieve a perfectly clean account in one session. It's to build a living, improving negative keyword strategy that gets more efficient over time. For more on how this fits into a broader PPC workflow, this overview of PPC workflow optimization is a useful companion read.

Putting It All Together

Eliminating irrelevant search terms isn't a one-and-done task. It's an ongoing part of running efficient Google Ads campaigns. But once you have a clear process in place, each review gets faster and your account gets cleaner. The wasted spend shrinks. The signal improves. And the keywords that are actually working get more of the budget they deserve.

Here's a quick checklist to keep handy as you work through this process.

1. Pull your Search Terms Report with at least 30 to 60 days of data.

2. Sort by cost and identify terms with no conversions and low relevance to your offer.

3. Decide whether negatives belong at the campaign level or in a shared list.

4. Choose the right match type. Negative phrase match is usually the safest starting point.

5. Build a reusable shared negative keyword list you can apply to future campaigns.

6. Schedule regular reviews, weekly or bi-weekly, to catch new irrelevant terms before they waste more budget.

If you're managing multiple campaigns or client accounts, doing this manually in spreadsheets adds up fast.
