What Are Negative Keywords in SEO and How Do They Work?

Negative keywords are terms that prevent paid ads from showing when a search contains a certain word or phrase. In SEO, they do not serve as a direct organic ranking control, but they help teams identify search intent that does not align with a page, offer, or audience.

For example, adding “free” as a negative keyword in a campaign or ad group tells Google Ads not to show the ad for searches that include “free.” On the Display Network, negative keywords may make an ad less likely to appear on sites whose content matches the excluded terms.

SEO Vocabulary Guide: The Key Terms You Need to Know

Search engine optimization has its own language, and knowing it changes how you read a report, evaluate a strategy, or brief a developer. The core seo vocabulary falls into three functional areas: on-page SEO, which covers content and page structure; off-page SEO, which covers backlinks and external authority signals; and technical SEO, which covers how search engines crawl, index, and interpret a site.

Each area has its own set of terms, and understanding how they connect is what separates a surface-level overview from a working knowledge you can act on.
