Negative Keywords: The Terms That Block Your Ads

Negative keywords are terms you exclude so your ads do not appear for searches that will not convert. This guide explains how they protect your budget.

Quick Definition

Negative keywords are terms you exclude so your ads do not appear for searches that will not convert.

What They Are

Negative keywords are terms that block your ad from appearing when a search contains them.

They are the flip side of the keywords you choose to target.

How They Work

When a search includes one of your negative keywords, your ad sits out of the auction entirely.

You win the matches you want and skip the ones you do not.

Why They Matter

  • Stops budget from leaking on irrelevant clicks.
  • Improves relevance, which helps your quality score.
  • Keeps campaign data clean and useful.
  • Lets your ads show where buyers actually search.

How to Use Them

  • Build a negative list before launching.
  • Review the search terms report regularly.
  • Add terms that spend without converting.
  • Revisit the list as your campaigns grow.
Example in Practice

The search: a budget ad triggers on the word cheap.

The block: the team adds cheap as a negative keyword.

The effect: the ad stops wasting spend on bargain hunters.

The lesson: negatives aim your ads at buyers.

Quick Tip
