Negative keywords in Google Ads: reduce irrelevant search traffic

Quick answer: exclude search intent you cannot serve, using the search terms report as evidence. A negative keyword is a targeting decision, not a punishment for a click without a sale.

Define what your business does not offer

List unsupported products, locations, audiences and services. A company selling professional equipment might not serve people searching for repair manuals, but the same phrase could be relevant to a repair business. Context matters more than a universal exclusion list.

Review actual search terms

Inspect available terms alongside spend, clicks, conversions and lead quality. Group unrelated searches by intent. When a query matches the offer but has no conversions, check tracking, conversion delay and sample size before excluding it. Not every zero is evidence of waste.

Choose the match type and scope carefully

Negative match behavior differs from positive keyword matching. Understand the phrase you are blocking and do not assume every close variant is automatically covered. Test whether the exclusion would also remove a valuable query.

Apply an exclusion at ad-group, campaign or shared-list level according to its purpose. A shared list affects multiple campaigns, so a narrow product decision can become an account-wide mistake if placed too broadly.

Document and review exclusions

Record the reason, evidence, scope and date of important exclusions. Review positive keywords against negatives when impressions fall unexpectedly. Check new product launches so an old exclusion does not silently block a newly supported offer.

Measure qualified demand, not just cheaper clicks

After a change, compare consistent periods and observe qualified leads or purchases. A lower cost per click does not automatically mean better customers. Avoid changing bids and landing pages at the same time if you need to understand the effect of exclusions.

For a wider review, use the Google Ads audit checklist. If relevant clicks still do not convert, follow the conversion diagnostic guide.
