How to Find Irrelevant Search Terms in Google Ads (And Stop Paying for Them)
This guide walks advertisers through exactly how to find irrelevant search terms in Google Ads using the built-in Search Terms Report, identify which queries are wasting budget, and build a repeatable negative keyword strategy to keep campaigns clean and conversion rates accurate.
Every time someone searches for something unrelated to your offer and clicks your ad, you pay for it. That's the core problem with broad and phrase match keywords: Google shows your ads for searches you never intended to target, and your budget quietly disappears into traffic that was never going to convert.
The result is wasted spend, inflated cost-per-click, and a conversion rate that looks terrible despite real effort on your part. The fix isn't complicated, but it does require knowing where to look and what to do with what you find.
This guide walks you through exactly how to find irrelevant search terms in Google Ads, how to tell which ones are actually hurting you, and how to take action so they stop burning your budget. Whether you're managing a single campaign or dozens of client accounts, the process is the same.
You'll use Google Ads' built-in Search Terms Report, apply the right filters, and build a negative keyword strategy that keeps your traffic clean going forward. No spreadsheets required.
By the end, you'll know precisely where your wasted spend is coming from and have a repeatable workflow for catching irrelevant terms before they do real damage. Let's get into it.
Step 1: Open the Search Terms Report in Google Ads
Before you can fix anything, you need to see what's actually happening. That means getting into the Search Terms Report, which is where Google shows you the actual queries that triggered your ads.
Here's an important distinction to get right from the start: keywords are what you bid on. Search terms are what users actually typed into Google before clicking your ad. These are not the same thing, and confusing them is one of the most common mistakes in PPC audits.
When you set a keyword to broad or phrase match, Google uses its own matching logic to decide which real-world queries are "close enough" to show your ad. Sometimes that logic works well. Often it doesn't. The Search Terms Report is the only place you can see exactly what Google decided to match.
How to get there: In the Google Ads interface, navigate to the left-hand menu and select a campaign. Then look for Search Keywords in the secondary navigation, and click the Search Terms tab. Alternatively, you can go to Reports > Predefined reports > Basic > Search terms to see data across campaigns at once.
Don't confuse the Keywords tab with the Search Terms tab. The Keywords tab shows the terms you're actively bidding on. The Search Terms tab shows what real users searched for. You need the latter.
Once you're in the report, you're looking at raw data: every query that triggered an impression or click within your selected date range. This is the foundation of everything that follows.
Tip on date range: Set your date range to at least 30 days before you start reviewing. Shorter windows miss patterns. A week of data might show a few odd search terms, but 30 to 90 days will reveal the recurring problems that are genuinely costing you money. If you set the range too short, you'll end up chasing noise instead of fixing real issues.
Step 2: Set the Right Date Range and Filters
Now that you're in the Search Terms Report, the next step is narrowing the data down to what actually matters. A large account can generate thousands of unique search terms in a month. You don't need to review all of them. You need to review the ones that are already costing you money, or are about to.
Choose your date range with purpose. For a first-time audit, 30 to 90 days gives you a solid sample. If you're doing an ongoing review, the last 7 to 14 days is usually enough to catch new problem terms before they accumulate more spend.
Once the date range is set, use the filter tool to remove the noise. Here's how to think about it:
Filter by Cost greater than $0: This removes search terms that triggered impressions but no clicks. Those terms aren't spending your budget, so they're lower priority right now. Focus on terms that have already cost you something.
Filter by Clicks or Impressions above a threshold: If you want to catch high-volume irrelevant terms before they accumulate spend, filter by impressions. A term with thousands of impressions and zero conversions is a problem even if the CPC is low.
Segment by campaign or ad group when your account has multiple campaigns with different intent. A search term might be perfectly relevant for one campaign and completely wrong for another. Reviewing everything in one undifferentiated view can lead to poor decisions about where to add negatives.
The goal of filtering is to prioritize action. You want to fix what's already costing money first, then work backward toward high-volume terms that haven't spent much yet. This order matters because it creates the fastest improvement in your account's efficiency.
If you're doing a first-time audit on an account that's been running for months without this kind of review, cast a wide net initially. You'll likely find a backlog of irrelevant terms that have been quietly accumulating. Once you've cleared that backlog, future reviews become much faster because you're only looking at new terms since your last check.
Step 3: Understand What "Irrelevant" Actually Means for Your Campaign
This step is where most guides fall short. They tell you to look for irrelevant terms but don't explain how to actually identify them. "Irrelevant" isn't always obvious, and it's not the same as "underperforming."
Here's a practical way to think about it: a search term is irrelevant if someone searching that query would have no reasonable intent to buy, use, or even seriously consider what you're offering. The question to ask yourself is: would this person convert, given what my landing page offers? If the honest answer is no, the term is irrelevant.
Some categories of irrelevant terms are easy to spot:
Job and career intent: Searches containing words like "jobs," "salary," "careers," "how to become," or "certification" suggest someone looking for employment, not a product or service. If you sell project management software, you don't want to pay for someone searching "project manager salary."
Free or DIY intent: Searches with "free," "DIY," "template," or "open source" signal that the user is looking for a no-cost solution. If you're selling a paid product, these users are unlikely to convert regardless of how good your ad is.
Informational or academic intent: Queries starting with "what is," "history of," "definition," or "how does X work" usually indicate research mode, not purchase mode. These users may eventually become buyers, but they're not ready now, and paying for their clicks is rarely efficient.
Wrong audience signals: This one requires knowing your customer. A SaaS company bidding on "project management" might get triggered for "project management degree program." The keyword overlap is real, but the audience intent is completely different.
Now here's the distinction that matters: irrelevant is not the same as underperforming. A search term can be relevant to your offer but simply haven't generated a conversion yet because it hasn't had enough traffic. Before you exclude a term, ask whether it's genuinely off-target or just needs more data. Low spend, low volume, and zero conversions on a relevant term is a data problem, not necessarily an audience problem. Don't add negatives based on thin data for terms that are actually on-topic.
Step 4: Sort and Scan for Patterns in Irrelevant Traffic
You don't need to read every search term line by line. That approach doesn't scale, and it leads to analysis paralysis. What you're looking for are patterns, because one negative keyword can often block dozens of irrelevant variations at once.
Start by sorting by Cost, descending. This surfaces the search terms that have already spent the most money. These are your highest-priority targets. If a term has cost you meaningful budget and produced no conversions, that's where you act first.
As you scan, look for recurring modifier words that consistently signal wrong intent. Common ones include:
"free" appearing in any variation: "free project management tool," "free CRM," "free template"
"how to" when you're targeting buyers, not learners: "how to write a project plan," "how to manage a team"
"jobs," "salary," "careers," "hiring" when your product isn't employment-related
"template," "example," "sample" when you sell software, not documents
"what is," "definition," "meaning of" when you're targeting purchase-ready users
When you spot one of these modifiers appearing repeatedly across different search terms, that's a signal that a single phrase match negative keyword can block all of them at once. You don't need to add "free project management tool," "free CRM software," and "free task tracker" as separate negatives. Adding "free" as a phrase match negative handles all of them.
After sorting by cost, sort by Impressions, descending. This reveals high-volume irrelevant terms that haven't spent much yet but will as the campaign continues. Catching these early prevents future waste rather than just cleaning up past waste.
The mindset here is pattern recognition, not line-by-line review. Spot the modifier, understand the intent it signals, and plan a single negative that blocks the category rather than the individual term.
Step 5: Add Irrelevant Terms as Negative Keywords
You've identified the problems. Now you fix them. Adding negative keywords is how you tell Google not to show your ads for searches that don't match your offer.
The mechanics in Google Ads: In the Search Terms Report, use the checkboxes to select the irrelevant terms you've identified. Once selected, an option to "Add as negative keyword" appears. Click it, and Google will prompt you to choose where to add the negative and what match type to use.
Before you click through, you need to make two decisions: scope and match type.
Scope: campaign-level vs. ad group-level. If a search term is irrelevant to your entire campaign, add the negative at the campaign level. If it's only irrelevant for a specific ad group but might be valid elsewhere in the campaign, add it at the ad group level. When in doubt, start at the campaign level for clearly off-topic terms and use ad group-level negatives for more nuanced exclusions.
Match type for negative keywords. This is where a lot of advertisers get confused, because negative keyword match types work differently from positive keyword match types.
Exact match negative (written as [term]) blocks your ad only when the search query matches that exact phrase in that exact order, with no additional words. Use this for very specific irrelevant terms where you want precise control. For example, [project management certification] blocks that exact query without affecting searches for "project management software" or "project management tools."
Phrase match negative (written as "term") blocks any query that contains that phrase as part of it. This is more aggressive and more efficient for pattern-based exclusions. Adding "free" as a phrase match negative blocks any search containing the word "free," regardless of what surrounds it. Use this for modifier words that consistently signal wrong intent.
Broad match negative blocks searches containing all the words in your negative keyword, in any order. This is the least precise option and can accidentally block relevant traffic if you're not careful. Use it sparingly.
A practical approach: use exact match negatives for specific irrelevant terms you've identified, and phrase match negatives for the recurring modifier patterns you spotted in Step 4.
Negative keyword lists for scale. If you manage multiple campaigns or client accounts, adding negatives directly to individual campaigns gets tedious fast. Google Ads lets you create shared negative keyword lists that you can apply across multiple campaigns at once. Building a master list of known irrelevant terms and applying it account-wide is far more efficient than adding the same negatives campaign by campaign.
If you're doing this workflow regularly across multiple accounts, Keywordme lets you flag and add negative keywords directly from the Search Terms Report with one click, without leaving Google Ads or opening a spreadsheet. It's built specifically for this kind of repetitive, high-frequency task, and it significantly reduces the time spent on each review cycle.
Step 6: Build a Repeatable Review Schedule
Here's something most guides won't tell you: a one-time cleanup isn't enough. Google's matching logic evolves, campaigns accumulate new data, and new irrelevant search terms will appear on an ongoing basis. The work you did today keeps your account clean for now, but it won't stay that way without regular attention.
Think of the Search Terms Report like email. You can't just read it once and consider it handled. New messages keep arriving.
How often should you review? For active campaigns with meaningful daily spend, a weekly review is a reasonable target. You're not doing a deep audit every week; you're scanning for new patterns and adding negatives for anything that's accumulated cost without converting. These reviews get faster over time as your negative keyword list grows and filters out more irrelevant traffic before it reaches your report.
For smaller budgets or lower-volume campaigns, a bi-weekly or monthly review is usually sufficient. The key is consistency, not frequency. A monthly review done reliably is more valuable than weekly reviews that get skipped whenever things get busy.
Your first review is always the longest. If you're auditing an account that hasn't had this kind of attention before, expect to spend real time on the initial pass. That's normal. You're clearing a backlog. Once that's done, you're maintaining a system rather than building one from scratch, and each subsequent review takes a fraction of the time.
Use shared negative keyword lists. As you build your exclusion set over time, organize it into a shared negative keyword list in Google Ads. This lets you apply the same exclusions across multiple campaigns simultaneously. When you identify a new irrelevant modifier, you add it once to the list and it propagates everywhere the list is applied.
How to know it's working: Over time, you'll see the ratio of relevant to irrelevant search terms in your report improve. Your click-through rate will rise because your ads are showing for more targeted queries. Your cost per conversion will drop, not because of bidding changes, but because the traffic reaching your landing pages is more qualified. These are the signals that your negative keyword strategy is doing its job.
Putting It All Together
Finding and removing irrelevant search terms isn't a one-time project. It's an ongoing habit that keeps your Google Ads budget working on traffic that can actually convert.
The process is straightforward: open the Search Terms Report, set a meaningful date range, filter by cost and impressions to prioritize action, identify what doesn't match your offer, add those terms as negative keywords at the right scope and match type, and repeat on a schedule. Each time you go through this cycle, your negative keyword list gets stronger and your traffic gets cleaner.
The first review takes the most effort. Everything after that is maintenance, and it gets faster as your exclusion list does more of the filtering work for you.
If you're managing multiple campaigns or client accounts and want to move through this workflow faster, Keywordme is built exactly for this. It lets you flag irrelevant terms and add them as negative keywords without leaving the Google Ads interface, no spreadsheets, no tab-switching, just quick one-click actions directly in the Search Terms Report.
