What negative keywords do
A negative keyword tells Google not to show your ad when that term is in the search. If you add free as a negative, your ad will not show for free plumber. Negatives are how you filter out searches that waste budget without losing the ones that convert.
What to check first
- Review the search terms report.
- List the terms you never want to trigger your ads.
- Check for overblocking by reviewing what you excluded.
- Use shared negative lists for common exclusions.
- Review negatives regularly as search behavior changes.
Match types for negatives
Negatives also have match types. A broad negative blocks more variations. A phrase negative blocks the exact phrase and close variants. An exact negative blocks only that exact term. Use the right match type so you block what you intend without catching good searches.
Overblocking good traffic
The danger of negatives is blocking traffic you want. If you add service as a negative to block free service, you may also block service plumber. Check what you exclude and use more specific negatives to avoid catching good searches in a broad block.
Brand and location terms
Consider whether to negative your own brand terms on generic campaigns to avoid competing with yourself. For location, add negatives for areas you do not serve so you stop paying for clicks from outside your region. Both are common sources of waste when ignored.
A review process
Negatives are not set and forget. Search behavior changes and new irrelevant terms appear. Review the search terms report weekly at first, then monthly. Add new negatives and check that existing ones are not blocking good traffic. A maintained negative list keeps the campaign clean.

- 2.Add irrelevant terms as negatives with the right match type.
- 3.Use specific negatives to avoid overblocking.
- 4.Build shared lists for common exclusions.
- 5.Review and adjust the list regularly.
