One wrong negative keyword can stop a keyword you pay for from showing. Paste both lists: the checker shows which keywords are blocked on their own search, and by which negative.
You paste your keywords and your negative keywords, one per line, with Google Ads notation: "phrase", [exact], and a leading minus sign is accepted. The checker applies the negative matching rules and lists each blocked keyword with the negative responsible.
The tool needs JavaScript to run.
One keyword per line, with or without notation: quotes, brackets and +word are accepted. The checker tests the keyword text itself, as if someone typed exactly that search.
One negative per line. Write free for broad match, "free estimate" for phrase match, [free estimate] for exact match. A leading minus sign (-free) is accepted.
Each blocked keyword shows up with the negative responsible and the rule applied. The “Example” button shows one case of each type.
Remove the negative, switch it to phrase or exact match so it blocks fewer searches, or drop the keyword if it no longer belongs.
Google Ads applies a different rule depending on the negative keyword's match type. The checker applies the same ones:
The keywords you bid on can match close variants such as plurals and misspellings. Negative keywords do not: “repair” blocks neither “repairs” nor “repiar”.
The checker follows the same rule. It only flags a conflict when the words are identical, ignoring capital letters. A plural keyword can slip past a singular negative, and the other way around.
Negatives pile up: one for the campaign, another added from the search terms report, a shared list applied to several campaigns. A negative that makes sense for one offer can block a keyword in another campaign that uses the same list.
The keyword stays active in your account, but it can no longer show on the search it describes. Starting from a reviewed base lowers the risk: our negative keyword lists by industry already flag the terms that may be your product.
The checker tests the text of each keyword. A broad match keyword also shows on other searches, and a negative can block some of them: that is often the point, and it is not a conflict.
It does not know your account structure either. Paste together the negatives that apply to the same keyword: those of its ad group, its campaign and the lists attached to that campaign. To add the right notation to a whole list, use the keyword match type generator.
A conflict costs you customers; a missing negative makes you pay for clicks with no buying intent. Should I Bid reads the Google results page for each keyword before you pay, checks it against your offer and gives a verdict: Bid, Test or Skip. Its analysis also recommends the negatives to add.
A keyword that one of your negatives stops from showing on its own search. For example, free as a broad match negative blocks the keyword “free roof inspection”.
No. Negative keywords do not cover close variants. The negative repairs does not block “roof repair denver”, so the checker does not flag it.
No. In Google Ads, negatives go in a field made for them, without a minus sign. The checker accepts both, so you can paste a list prepared elsewhere.
All those that apply to the keyword: its ad group's, its campaign's and the negative keyword lists attached to that campaign. A negative from another campaign does not block this keyword.
You have three options: remove the negative if it no longer helps, make it narrower with phrase or exact match, or drop the keyword if it no longer fits your offer.
No. The check runs in your browser: nothing is sent or stored.
