Fix negative keywords that don't block the searches you added them for

Find the search that still gets through in the Search terms report, then compare it with your negative word by word. Negatives skip plurals, synonyms and close variants, so add each form. An exact match negative blocks only that exact search. Then confirm the negative or its list applies to the campaign the search came from.
Before you start
- Standard or Admin access to the Google Ads account, since adding or applying a negative keyword is an edit.
- The date you added the negative, so you can look only at searches made after it. Change history shows it if you do not know.
- One search that got through, copied exactly as the report shows it.
Find the search that got through
- Click Campaigns, then Insights and reports, then Search terms. Set the date range to start the day after you added the negative, since older rows prove nothing.
- Find the search you meant to block. Note the campaign and ad group it came from. If those columns or Keyword are not showing, add them from the Columns icon above the table.
- Compare the search with your negative and mark every difference: a plural, a synonym, an extra word or a different order.
Match the negative to the search
Negatives do not stretch to close variants the way keywords do, and Google Ads does not list the forms a negative misses. Google's example: the negative "flowers" blocks "red flowers" but not "red flower".
- If the search has the singular where your negative has the plural, or the other way round, add that form as its own negative. A dental office that blocks "implant" can still show for "implants" until both are listed.
- Add synonyms the same way: blocking "jobs" does not block "careers". Capital letters and misspellings are covered.
- Square brackets, such as [free consultation], mean exact match: it blocks only that search with no extra words, and the report adds negatives this way. Replace it with the word that makes the search wrong, alone and without symbols, as broad match.
- Quotation marks mean phrase match, which needs the same word order: "divorce lawyer free" does not block "free divorce lawyer". Broad match blocks the words in any order.
- A minus sign inside a negative is ignored along with its word: dark -chocolate is treated as dark. Google also treats café and cafe, or & and the word and, as different negatives, so add both.
To change a negative's text or match type, hover over it, click the pencil icon, make the change and click Save.
Put the negative where the search ran
A negative only covers the place it was added. An ad group negative does nothing for another ad group or campaign.
- Click Campaigns, open Audiences, keywords, and content, click Search keywords and open the Negative search keywords tab. Find your negative and read which campaign or ad group it belongs to.
- If it belongs to a different ad group or campaign from the one in the report, add it to the campaign that showed the ad, or to a list that campaign uses.
- If the negative lives in a negative keyword list, click Tools, open Shared library, click Exclusion lists and open the Negative keyword lists tab. A list does nothing until it is applied. Tick the list, click Apply to campaigns, tick the campaign from the report and click Done.
- To block a word across the search and shopping ads of every campaign, Performance Max included, click Admin, then Account settings, expand Negative keywords, click the plus button, enter one word or phrase per line and click Save. Google allows 1,000 negatives at the account level.
Check it worked
Wait a few days for new searches, then open Search terms again with the date range starting the day after your fix. The search should be gone, along with others that contain the word you blocked as broad match.
A missing row is not proof on its own, since the report leaves out searches only a few people made. If the same search appears again, compare it word by word a second time: look for a form you have not listed or a campaign the negative does not cover.
Why a negative can be ignored in a very long search
Google says your ad can still show when a search runs past 16 words and your negative comes after the 16th word.
Negatives in Performance Max, Display and Video
In Performance Max, negatives apply to Search and Shopping inventory only. In Display and Video campaigns every negative is treated as broad match, Google considers at most 1,000 of them, and it says an ad may still occasionally appear on a page containing an excluded word. For those networks, Google points to content exclusions and site categories instead.
