Negative Keywords

Negative keywords are terms you add to a PPC campaign to prevent your ads from showing for irrelevant searches. They help reduce wasted ad spend by filtering out traffic that is unlikely to convert. Negative keywords can be applied at the account, campaign, or ad group level and use three match types: broad, phrase, and exact, each controlling the scope of queries blocked. Why it matters: without a robust negative keyword strategy, a significant portion of your ad budget is spent on clicks from users with no intention of buying your product or service. For example, a premium software company bidding on "project management tool" might waste hundreds of dollars per month on clicks from users searching for "free project management tool" if "free" is not added as a negative. Studies estimate that 15 to 25 percent of search ad spend is wasted on irrelevant queries in accounts that do not actively maintain negative keyword lists. Building a strong negative keyword list begins with reviewing your search terms report to identify queries that triggered your ads but did not result in conversions. Common categories of negatives include competitors you do not want to bid against, job-related queries like "salary" or "hiring," informational terms like "what is" or "how to" when targeting transactional intent, and geographic terms for locations you do not serve. Maintaining a shared negative keyword list at the account level ensures consistent filtering across all campaigns, while ad group-level negatives allow for precise traffic sculpting between closely related keyword themes. Reviewing and updating negative keywords weekly or biweekly should be a standard part of every PPC management workflow.
