How to Eliminate Junk Keywords in Google Ads (Step-by-Step)

Junk search terms quietly eat through budgets in every Google Ads account, whether you're managing a single client campaign or a stack of them at an agency. The good news is that cleaning them up is a repeatable process, not a one-time scramble. By the end of this guide, you'll have a clear method for finding and removing wasteful search terms and keywords so your spend goes toward traffic that actually converts. You'll need an active Google Ads account with at least a few weeks of search history and admin or edit access to the campaigns you want to clean up.

Step 1: Pull Your Search Terms Report

Before you can eliminate junk keywords in Google Ads, you need to see what people actually typed to trigger your ads. As of 2026, you'll typically find this under Campaigns > Insights and Reports > Search terms, though Google periodically shuffles its navigation, so if that path doesn't match what you see, look for a Search Terms tab under Keywords instead.

It's worth pausing on a distinction that trips up a lot of advertisers: search terms and keywords are not the same thing. A keyword is what you bid on, like "email marketing software." A search term is what someone actually typed into Google, which might be "free email marketing software" or "email marketing software jobs." Junk almost always hides in the search terms, not the keyword list itself, which is exactly why this report is your starting point.

Set your date range to at least 30 to 60 days. A shorter window won't give you enough volume to spot real patterns, and you'll end up chasing noise instead of genuine waste. If your account has months of history and steady spend, consider pulling 90 days for a fuller picture, especially if your traffic has any seasonality.

Once the report loads, sort by cost or clicks in descending order. This puts your highest-spend, highest-click search terms at the top, which is where the real damage usually lives. A term that's burned $400 with zero conversions deserves attention long before a handful of $2 clicks. Work through the expensive rows first, then move down to lower-spend terms once you've handled the big offenders. This sorting step alone can save you an hour of scrolling through irrelevant rows in a large account.

Step 2: Spot the Patterns That Signal Junk

With the report sorted, you're looking for a few recurring signals. The clearest one is high impressions or clicks paired with zero conversions over your review window. A term that's generated dozens of clicks and no results is either poorly matched to your offer or attracting the wrong audience entirely.

The second signal is topical mismatch: search terms that have nothing to do with what you sell. If you run a project management SaaS tool and see "project manager job description" or "free project management templates," those clicks are coming from people looking for information or employment, not software. The third signal is intent mismatch, where the topic is right but the buying stage is wrong. Words like "free," "cheap," "diy," or "jobs" attached to an otherwise relevant term usually mean the searcher isn't ready to pay for what you're selling.

A common mistake here is dismissing low-volume irrelevant terms as harmless because each one only cost a dollar or two. Individually they look trivial. Added up across a month, a hundred small irrelevant clicks can quietly consume a meaningful chunk of budget that never had a shot at converting. Treat pattern-matching, not just individual dollar amounts, as your filter.

For example, imagine a B2B SaaS company running a broad match campaign for "PPC management." Over a few weeks, the search terms report might surface queries like "ppc course free," "google ads jobs," and "ppc management for dummies." None of these searchers want to buy PPC management services. They're students, job seekers, or DIYers, and broad match happily served them ads anyway. Left unchecked, these terms could quietly consume a meaningful slice of the daily budget without a single conversion to show for it.

Once you've flagged the offenders, group them mentally by cause, whether that's intent mismatch, topic mismatch, or plain irrelevance, because that grouping will make Step 3 faster.

Step 3: Add Negative Keywords at the Right Level

Once you've identified junk search terms, the fix is a negative keyword: a term you tell Google Ads not to match your ads against. Negative keywords come in the same three match types as regular keywords, but they work in reverse.

• Broad match negative: blocks any search containing all the words in the negative, in any order, plus close variants. Adding "free" as a broad negative blocks a wide range of queries containing that word.
• Phrase match negative: blocks searches that contain the exact phrase in that order, allowing extra words before or after. "Free trial" as a phrase negative blocks "best free trial" but not "trial for free."
• Exact match negative: blocks only the precise search term (or very close variants), so "free trial" as an exact negative only blocks that specific query.

Next, decide where the negative belongs. If a junk term is a one-off problem specific to a single campaign, add it as a campaign-level negative. If it's a recurring issue across several campaigns, for example, a competitor name or a word like "jobs" showing up everywhere, a shared negative keyword list applied across multiple campaigns is more efficient and keeps your account consistent.

The mistake to watch for is going too broad with a negative and accidentally blocking traffic that actually converts. Before saving, check what other search terms currently match that negative's pattern. Adding a broad negative for "free" could inadvertently exclude "free consultation," which might be a legitimate high-intent phrase for your business. When in doubt, use a narrower match type first and widen it only if the junk keeps slipping through.

Step 4: Clean Up Existing Keywords, Not Just Search Terms

Excluding search terms handles symptoms, but it doesn't always fix the root cause. If a broad match keyword like "project management" keeps generating irrelevant search terms week after week, you can add negatives forever and new junk variants will keep slipping through, because the keyword itself is too loosely matched.

This is where you go back to your actual keyword list, not the search terms report, and audit what's there. Look for a few specific problems:

• Duplicate keywords across ad groups or campaigns that compete against each other in auctions
• Keywords still set to broad match that consistently pull in low-quality traffic despite negative keyword cleanup
• Keywords with no impressions in the last 90 days, which are dead weight cluttering your account
• Keywords with meaningful spend and no conversions over your review window, which suggests the keyword itself, not just certain search terms it triggers, is the problem

For keywords with high spend and no conversions, consider pausing or removing them outright rather than just layering on more negatives. If a broad match keyword is the source of repeated junk, tightening it to phrase or exact match often solves the problem at the root instead of chasing every new variant it produces.

The key distinction to keep in mind: excluding a search term stops that specific query from matching in the future, but it doesn't change the keyword that triggered it. The same broad-match keyword can and will surface new junk variants next month. Treating your keyword list and your search terms report as two separate cleanup jobs, rather than one, closes that gap.

Step 5: Speed Up the Process With One-Click Tools

Doing Steps 1 through 4 manually works, but it's slow. Exporting search terms to a spreadsheet, sorting and filtering there, then flipping back to Google Ads to add each negative one by one adds friction, and that friction adds up fast if you're managing more than one account.

Keywordme is a Chrome extension built to remove that friction by working directly inside the native Search Terms Report in Google Ads. Instead of exporting data to a spreadsheet, you review flagged search terms in the same interface you already use, and apply actions like removing junk terms, adding negative keywords, or setting match types with a click. It's worth being clear about what this does and doesn't do: Keywordme speeds up manual review and application, it doesn't scan your account and apply changes automatically without your input. You're still the one deciding which terms are junk. The tool just removes the extra steps of exporting, formatting, and re-uploading.

As an illustrative workflow, imagine you've just finished Steps 1 and 2 and have a list of ten junk search terms flagged in your head. Instead of opening a spreadsheet, copying terms, and navigating to the negative keyword list manager, you'd work through that same Search Terms Report in your browser, applying negatives to each flagged row as you go, without ever switching tabs or exporting a file. For agencies juggling multiple client accounts, Keywordme also supports multi-account and team access, along with bulk editing, which matters when you're repeating this cleanup across a dozen campaigns instead of one.

Step 6: Build a Shared Negative Keyword List

Certain junk terms show up over and over, no matter which campaign you're running. Competitor names you don't want to pay for, words like "free," "cheap," "jobs," and "diy," and industry-adjacent terms that never convert are good candidates for a shared negative keyword list rather than one-off campaign exclusions.

A shared list lives at the account level and can be applied to as many campaigns as you choose, so you only have to add a recurring junk term once instead of duplicating it everywhere. This is especially useful if you're an agency owner managing several client accounts in the same industry. A master list of common junk terms, informational queries, job-seeker language, and mismatched intent phrases gives you a starting point for every new account, which you then customize based on what that specific client's search terms report reveals.

Keep the list organized by theme rather than dumping everything into one undifferentiated pile. Group entries under categories like intent mismatch ("free," "cheap," "diy"), informational queries ("how to," "what is," "guide"), and irrelevant industries or roles ("jobs," "salary," "course"). This structure makes the list far easier to audit later, since you can scan by category instead of rereading every single term to remember why it's there.

Step 7: Set a Recurring Review Schedule

A single cleanup pass won't keep your account junk-free for long. Search behavior shifts, Google's matching logic evolves, and new campaigns or keywords introduce fresh opportunities for irrelevant traffic to creep in. Treat Steps 1 through 4 as a cycle, not a one-time project.

For high-spend accounts, a weekly review makes sense, since waste accumulates faster when daily budgets are large. For smaller accounts with modest spend, biweekly or monthly reviews are usually enough to stay on top of new junk without over-investing your time. Put it on a calendar with a recurring reminder rather than relying on memory, because this is exactly the kind of maintenance task that gets skipped when things get busy.

It also helps to track a simple metric over time: wasted spend recovered per review cycle, meaning the cost of the search terms and keywords you excluded or paused. This doesn't need to be complicated. Even a rough running total, campaign by campaign, gives you something concrete to show a client or a stakeholder who wants proof that ongoing optimization work is paying off, rather than just taking your word for it.

Making Cleanup Part of Your Routine

Cutting junk keywords once feels good, but the accounts that stay lean are the ones where this becomes a habit rather than a project. Repeat this process on a schedule and you'll steadily shrink wasted spend from irrelevant search terms instead of watching it creep back in. Start your review this week using your current search terms report, and if the manual cleanup across steps starts eating more of your time than it's worth, consider a tool built for exactly this.
