How to Stop Losing Money on Bad Search Queries in Google Ads

If your Google Ads account has been running for more than a few weeks, some percentage of your budget is going toward searches that were never going to convert. That's not a knock on your account setup, it's just how broad match and auto-applied recommendations behave over time. This guide walks you through finding those wasted clicks, cutting them off, and redirecting that spend toward searches that actually convert. You'll need an active Google Ads account with at least one search campaign that has some run time on it, plus edit access so you can add negative keywords when you find them.

Step 1: Pull Up Your Search Terms Report

Everything in this guide starts with one report. As of 2026, you'll find it by going to Campaigns, then Insights and reports, then Search terms (Google occasionally shuffles menu labels, so if the path looks slightly different, look for "search terms" under reporting or insights). This report shows you the actual words and phrases people typed into Google before your ad showed up.

That's different from your keyword list. A keyword is what you bid on, the term you told Google Ads to match against. A search term is what a real person actually typed. Google's match types (broad, phrase, exact) determine how loosely or tightly your keyword connects to the searches that trigger it. Broad match in particular can trigger your ad for searches that share only a loose thematic connection to your keyword, not the same intent.

Before you look at any numbers, widen your date range. A single day or even a week of data can make a perfectly fine keyword look like a problem, or hide a slow-bleeding one. Pull 30 to 90 days, depending on how much traffic the campaign gets. High-volume campaigns can often get a clear picture in 30 days. Lower-volume accounts need the full 90 to see real patterns instead of noise.

Once the report loads, you're looking at a list of every search term that triggered an impression or click, along with clicks, cost, conversions, and conversion value next to each one. That's your raw material for the next step. Don't try to make judgment calls yet, just confirm the report is pulling data across your full date range and across all campaigns you want to review, not just one.

Step 2: Flag the Search Queries Costing You Money

With the report open, sort by cost first, then by clicks. This puts your biggest spenders at the top, which is where waste tends to hide in plain sight. For each term near the top, check the conversions column. A term with meaningful spend and zero or near-zero conversions is your first red flag.

As you scan down the list, watch for a few recurring patterns:

• Irrelevant intent: job seekers ("how to become a [your service] technician"), DIY searchers ("fix [your product] myself"), or people looking for a specific competitor by name.
• Near-miss broad match expansions: terms that are topically related to your keyword but miss the actual intent, like someone searching for repair or reviews when you sell new products.
• Informational queries: anything starting with "what is," "how does," or "why" that suggests someone researching rather than ready to act.

The most common mistake at this stage is judging a term too early. Three clicks and no conversion doesn't mean a search term is bad, it might just mean you haven't seen enough volume yet to know. Conversion rates need a reasonable sample before you can trust them. As a rough gut check, wait until a term has accumulated cost close to what you'd normally spend to get one or two conversions elsewhere in that ad group before writing it off. If your typical cost per conversion is $40 and a term has spent $15 with no conversions, that's not damning yet. If it's spent $200 with nothing to show for it, that's a clear candidate for the next step.

Step 3: Add Negative Keywords to Block the Waste

Once you've flagged a search term as waste, a negative keyword is how you tell Google Ads to stop showing your ad for that search. Negative keywords use the same three match types as regular keywords, but in reverse.

• Negative broad match blocks any search containing all the words in your negative, in any order. Adding "free" as a negative broad blocks "free shipping quotes," "quotes for free," and similar variations.
• Negative phrase match blocks searches containing that exact phrase, in that order, though other words can appear around it.
• Negative exact match only blocks the search term that matches exactly, word for word.

You also need to decide where the negative lives. Add it at the ad group level if the term is only irrelevant for that specific ad group but might still be valid for another ad group in the same campaign. Add it at the campaign level if the term is irrelevant everywhere in that campaign. If it's irrelevant across your entire account, you'll want a shared list, which is covered in Step 5.

The mistake to watch for here is over-blocking. A negative broad match keyword can cut off far more traffic than you intended if the words in it are common. Adding "shoes" as a negative broad in a running shoes campaign, for example, could block searches you actually want. Before you save a negative, think through what other searches contain those same words and whether you'd be comfortable losing that traffic too. When in doubt, start with phrase or exact match negatives, they're more surgical and less likely to create collateral damage.

Step 4: Review Your Match Types on Existing Keywords

Adding negatives treats the symptom. Reviewing match types addresses the cause. Broad match keywords are the most flexible for reaching new searches, but they're also the biggest source of irrelevant search terms if left unchecked. Google's matching system for broad match considers signals like your landing page, other keywords in the ad group, and past search history, which means it can drift further from your original intent than phrase or exact match would.

Go back to your search terms report and filter or sort by keyword, then look at the match type column alongside it. If a broad match keyword is consistently triggering search terms that miss the mark, that's a sign to tighten it rather than keep adding negatives one at a time.

For example, imagine a broad match keyword like "running shoes" pulling in a search term like "running shoes repair near me." That's not the same buyer intent as someone shopping for new shoes, but broad match doesn't know the difference on its own. In this case, you have two options: add "repair" as a negative, or convert the keyword itself to phrase match ("running shoes") so it only triggers on searches containing that phrase, cutting off a chunk of the irrelevant expansion at the source.

Neither move is universally right. Tightening match types reduces reach along with waste, so it works best when a keyword has enough historical data to show a clear pattern, not just one or two bad search terms. If a broad match keyword is otherwise performing well and only occasionally throws off a junk term, negatives alone are usually the better fix.

Step 5: Build a Negative Keyword List You Can Reuse

Certain junk search terms show up again and again across every campaign you run, job-related searches, "free" searches, DIY and repair searches. Instead of adding these one at a time in every campaign, build a shared negative keyword list in Google Ads and apply it wherever it's relevant. This saves you from repeating the same cleanup work every time you launch a new campaign.

To set one up, go to your account-level negative keyword lists (found under Tools and Settings in the Google Ads interface, as of 2026), create a new list, and add your recurring terms grouped by theme: job-seeker terms, free-seeker terms, DIY terms, competitor names. Then apply that list to any campaign where those terms don't belong.

This is also where a tool like Keywordme can save real time. Instead of jumping between the search terms report, a spreadsheet, and the negative keyword list manager, Keywordme lets you flag a junk search term and add it as a negative directly inside the native Search Terms Report with one click, and build out reusable negative keyword lists without leaving the Google Ads interface. For a freelancer or small agency managing several accounts, that removes a lot of the tab-switching and manual re-entry that makes this kind of cleanup tedious enough to get skipped.

Whether you build the list manually or with a tool, the goal is the same: turn one-time waste-cutting into a system you don't have to rebuild from scratch on every new campaign.

Step 6: Redirect Budget Toward High-Intent Terms

Cutting waste is only half the job. The other half is noticing which search terms are already converting well but haven't been added as their own keywords yet. These are hiding in the same search terms report you've been using to find junk, just at the opposite end of the performance spectrum.

Sort your search terms report by conversions or conversion value instead of cost. Look for search terms with strong conversion performance that don't yet appear as exact-match keywords in your account. If a broad match keyword is generating those conversions indirectly, you're leaving control on the table. Adding the exact search term as its own keyword, with a tighter match type like phrase or exact, gives you more control over bidding and ad copy for that specific query, and it typically improves Quality Score signals because your ad and landing page can speak more directly to that search.

Suppose your search terms report shows "waterproof running shoes women" converting consistently at a strong rate, but your account only bids on "running shoes" broad match. Adding "waterproof running shoes women" as an exact-match keyword lets you set a bid specifically for that high-intent search, write ad copy that speaks directly to it, and track its performance independently instead of it being buried inside a broader keyword's numbers.

This is another spot where Keywordme's in-report workflow helps. Instead of exporting the search terms report to a spreadsheet, cleaning it up, and re-uploading new keywords through the bulk editor, Keywordme lets you select a high-intent search term inside the Search Terms Report and add it as a new keyword with the match type applied directly, in the same view where you spotted it. That keeps the whole process, cutting waste and adding winners, inside one workflow instead of two separate tools.

Step 7: Set a Recurring Review Schedule

A single cleanup pass will stop the bleeding for a while, but new junk search terms show up as Google's matching evolves and as seasonal search behavior shifts. Treat this as a recurring task, not a one-time project.

How often you need to check depends on spend volume. Accounts spending a few hundred dollars a day can usually get by with a biweekly review. Accounts spending several thousand a day should check weekly, since waste accumulates faster and can eat a meaningful chunk of budget before your next scheduled look.

Beyond just adding negatives each time, track your wasted spend as a trend over several review cycles. If the dollar amount going toward zero-conversion search terms is shrinking review over review, your negatives and match type changes are working. If it's holding steady or creeping back up despite regular cleanup, that's a signal to stop treating individual search terms and go back to Step 4. Recurring waste from the same type of query usually means a match type, not a missing negative, is the root cause.

Keep a simple log of what you've added each cycle, whether that's a spreadsheet note or just relying on your negative keyword list's change history. It helps you spot whether you're fixing new problems each time or fighting the same one repeatedly.

Making Waste-Cutting Part of Your Routine

Cutting wasted spend from search queries isn't a task you finish, it's a habit you keep up alongside the rest of your account management. The accounts that stay clean are the ones where someone checks the search terms report on a schedule, not the ones that did one big cleanup back when they first noticed the problem.

If you're managing this weekly cleanup by hand, across multiple client accounts, that habit gets expensive in time even after it saves you money in ad spend.
