Negative keywords tell Google Ads which searches you don't want your ads to appear for. This PDF gives you themed starting lists to adapt:
Negative keywords behave differently from the keywords you bid on, and the PDF explains each type with an example:
The catch: negatives won't pick up plurals, synonyms or near variations, so list those separately. Capital letters and misspellings are now handled automatically.
Every click on a search that was never going to convert still costs you. Broad match can show your ads for a wide range of related searches, so a well-kept negative list helps keep your spend on people who might buy. Shared negative lists save time too: you build them once and apply them across campaigns.
Open your search terms report for the last few months and look for searches that could never lead to a sale. Compare them with the starter lists, then build your own shared lists, checking each word against your own products and services before you add it. Choose the match type deliberately: use phrase or exact negatives when a single word on its own could block good searches. Then make reviewing search terms part of a regular routine.
If your account has many campaigns, a large product range or years of accumulated negatives, conflicts become harder to spot: a negative in one list can quietly block keywords you're bidding on elsewhere. A PPC specialist can review existing lists, check for negatives that clash with active keywords and set up a review routine that suits the size of your account.
