How to Eliminate Junk Keywords with a Tool Inside Google Ads

Junk search terms quietly eat budget: the "free," "jobs," and "how to do it yourself" queries that your keywords matched but your business can't serve. This guide gives you a repeatable routine for finding those terms in your Search Terms Report and blocking them with negative keywords, using an eliminate junk keywords tool so you skip the spreadsheet exports.

Before you start, you need a Google Ads account with a Search campaign that has at least a few weeks of click data, plus a rough idea of what a good customer looks like.

Step 1: Define what counts as junk for your account

Junk is relative. A search term is junk if the person who typed it can't realistically become your customer. It is not junk just because it hasn't converted yet. Those are different things, and mixing them up is how people block good traffic.

Start with a short written list of irrelevant intents for your business. Common categories:

• Job seekers ("jobs," "careers," "salary," "apprenticeship")
• Freebie hunters ("free," "free template")
• DIY and learning intent ("how to," "course," "tutorial")
• Review-only or research-only intent, if you sell something people buy elsewhere
• Wrong product or service you don't offer
• Wrong location, if you serve a limited area

Get the terminology straight, because the fix depends on it. A keyword is what you bid on. A search term is what someone actually typed (see search terms vs keywords in Google Ads for the full distinction). You can't delete a search term. You eliminate junk by adding negative keywords, which tell Google not to show your ads for matching searches.

Finally, decide on a click threshold before you call anything wasted spend. Judging by conversions alone is the classic mistake with low-volume terms: a query with two clicks and no conversions tells you almost nothing. As an illustration, you might say a term needs to have spent one to two times your target cost per conversion without converting before you treat it as a problem. If your target is $40, that's $40 to $80 of spend. Pick your own multiple and stick to it.

Step 2: Pick a tool that works where you already review search terms

The best tool is the one that removes friction from a task you'll repeat every week or two. Compare options against these criteria:

• Does it work inside the Google Ads interface, or do you export and re-import?
• Can you add negatives in one click?
• Do you choose the match type for each negative?
• Does it handle multiple accounts?
• How is it priced (flat, per user, percentage of spend)?
• Do you stay in control of every change?

The realistic options:

• Manual review with spreadsheet exports. Free and flexible, but slow. You export, mark rows, then upload or re-enter negatives by hand.
• Google Ads scripts or automated rules. Good for mechanical checks, but they need setup and maintenance, and rules can't judge intent.
• Standalone dashboards. Often powerful, but they move you out of the account and can be heavy for a simple cleanup.
• In-interface extensions.Keywordme is a Chrome extension that adds actions to the Search Terms Report, so you remove junk terms, add negatives, and apply match types where you're already looking at the data. It also supports multi-account and team use.

On pricing, Keywordme costs $12 per month per user with a 7-day free trial, as of October 2026. Check the current figures on its site before you commit, since plans change. If you want to compare options side by side, see this roundup of search term report optimization tools.

One honest note: no tool decides what's junk for you. Whichever you choose, you review each term and you click. That's a feature, because your judgment from Step 1 is the filter.

Step 3: Open the Search Terms Report and set it up for review

In Google Ads, the Search terms report lives under Insights and reports in the left-hand menu (as of this writing; Google rearranges its navigation fairly often, so if you don't see it, use the search icon in the top bar and look for "Search terms"). You can view it at the campaign or ad group level, depending on what you've selected.

Then set it up so the review is quick:

1. Set the date range. Last 30 days works for most accounts. If volume is low, go back further so you have enough clicks to judge.
2. Filter to what you're cleaning. Select the Search campaign or ad group in question, so you don't mix in terms from other campaigns with different goals.
3. Sort by cost, descending. The biggest spenders come first, which is where cleanup pays off most. Sorting by clicks works too.
4. Add columns. Make sure conversions and cost per conversion are visible, along with match type, so you can see which keyword type is pulling in each term.

One pitfall to know about: Google only lists search terms that meet its volume and privacy thresholds. Spend on terms that fall below those thresholds is grouped under "Other search terms," so some of your budget goes to queries you can't see or block individually. Google explains this in its Help documentation on the search terms report. It means your report will never account for every click, and that's normal. Don't chase the hidden portion; clean what you can see, and let the patterns you find (Step 4) cover the rest.

Step 4: Flag the junk search terms

Work from the top of your sorted list. Focus first on high-spend terms with zero conversions, and for each one ask whether the intent matches your offer. The conversion count is a clue, not the verdict.

For example, imagine a plumber running ads for emergency callouts. Near the top of the report, next to real queries like "emergency plumber near me," they see "plumbing apprenticeship" and "how to fix leaky tap diy." Both have clicks, neither can become a customer. Those are easy flags. A term like "plumber salary" is the same story, a job seeker or student rather than a buyer.

Look for patterns rather than single terms. If "free," "jobs," "template," or "course" keep showing up in different queries, that single word is the real problem, and one negative can handle it. Scanning for repeated words saves far more time than judging each row alone, and it's the core idea behind removing junk search terms in Google Ads.

Borderline terms need a decision rule. If you can't tell whether a query could become a customer, and it hasn't hit your click threshold from Step 1, leave it alone and revisit after more data. Blocking on a hunch is how you lose good traffic. A wasted click on a maybe costs little; a negative that silently blocks a buyer costs every future click.

Mark your flags as you go. In Keywordme, you can select the junk terms directly in the report as you scan, so your review and your selection happen in one pass instead of two.

Step 5: Choose the right negative match type and level

Negative keywords have three match types: broad, phrase, and exact. They do not behave like their positive counterparts, and that catches a lot of people out. Per Google Ads Help, negative keywords don't match close variants, synonyms, or related searches the way positive keywords can. A negative for "job" won't automatically block "jobs" or "careers." Verify the current behavior on the Google Ads Help page for negative keyword match types, and add the variations you need yourself. If your blocks aren't working as expected, this guide explains why negative keywords sometimes fail to block searches.

How each one works:

• Negative broad: blocks searches containing all the negative's words, in any order, possibly with other words too.
• Negative phrase: blocks searches containing the words in that order, with other words allowed around them.
• Negative exact: blocks only the exact query, with no extra words.

A rule of thumb that holds up well:

• Use exact for a one-off bad query that sits near good ones. "plumber salary" blocked exactly leaves "plumber" queries alone.
• Use phrase for a recurring junk phrase, like "how to fix." More detail is in this guide to phrase match negative keywords.
• Use broad for a single word that is clearly irrelevant to everything you sell.

Now pick the level. You can add negatives to an ad group, a campaign, or a shared negative keyword list that you apply across campaigns. Use the ad group when the term is only junk for that theme, the campaign when it's junk for the whole campaign, and a shared list for account-wide junk such as "jobs" or "free" that no campaign should ever match. If you're unsure where each option lives in the interface, see where to add negative keywords in Google Ads.

The mistake to avoid: a broad negative that backfires. Words like "cheap" or "used" look like obvious junk until you sell budget services or secondhand equipment. Before you add any broad negative, ask whether any of your good customers could plausibly type that word. If yes, use phrase or exact instead.

Step 6: Add the negatives in bulk with one-click actions

This is where the tool earns its keep. Without one, you'd export the report, build a negatives sheet, and re-enter everything. With Keywordme installed, you stay in the Search Terms Report.

The flow, in general terms: select the junk terms you flagged, choose the match type for the negatives, and add them to the level you picked in Step 5. Keywordme's actions appear alongside the report itself, so there's no export. Button names and menu placement can change between versions, so follow the steps in Keywordme's current Help Center rather than relying on a label from this article. You still review and confirm each batch; nothing here is automatic. For more on this approach, see the overview of a negative keywords tool.

Use the same pass to grow your list. While you're in the report, you'll also spot search terms that are clearly good: relevant, converting, or obviously high intent. Select those and add them as positive keywords with the match type you prefer. The cleanup then does double duty: it removes waste and builds out the keyword list.

If you manage several clients, run the same routine in each account. Keywordme supports multi-account and team use, so you can apply one consistent process across accounts instead of reinventing it per client. Confirm how team seats work in the current plan details, since pricing is per user.

Before moving on, check that the changes landed. Open the negative keywords list in Google Ads, at the ad group, campaign, or shared list level you used, and confirm the new entries show up with the right match types. Catching a wrong match type now is much cheaper than finding it in next month's data.

Step 7: Check for conflicts and make it a routine

First, make sure your new negatives aren't blocking your own keywords. Google Ads can flag some cases where a negative conflicts with a keyword you're bidding on (check the current behavior in Google Ads Help, as it doesn't catch everything). Don't rely on that alone. Compare your new negatives against your active keyword list, and check impressions over the following days. A sudden drop on a keyword that was performing is the signal to look for a conflict.

Next, set a cadence tied to spend. As a suggestion rather than a benchmark: weekly for large budgets, where waste accumulates fast, and every two weeks to monthly for smaller ones. If a campaign is new or you've changed keywords or match types, review sooner, since that's when irrelevant queries tend to appear. Accounts that keep attracting off-target queries may need a deeper fix; this article on too many irrelevant keywords in Google Ads covers the common causes.

Keep a short change log. A shared doc or note is enough. For each batch, record the date, what you added, the match type, the level, and why. Clients and teammates can then review your reasoning, and you can undo a bad call quickly instead of guessing which negative caused a drop.

Finally, watch a few metrics over time:

• Cost per conversion
• Conversion rate
• The share of spend going to irrelevant terms, which you can estimate from your own flagged list each review

Compare against your own history, not an industry number. The goal is that each review finds a bit less junk than the last.

Check your results in two weeks, then keep the cycle going

After a couple of weeks, open the Search Terms Report again. Confirm that the junk you blocked has stopped showing up and that your good traffic hasn't dropped. If something valuable vanished, find the negative responsible and loosen its match type or remove it. Then put the next review on your calendar and repeat.

The routine gets faster each round, because your negative lists carry over and the new junk is usually a small batch rather than a pile.
