A summary generated directly by a search engine's AI system in response to a query, displayed prominently at the top of search results, synthesizing information from multiple sources into a single generated answer rather than linking to them individually.
Why it matters
AI overviews represent one of the most significant recent shifts in how search results are presented, directly contributing to zero-click search and changing what "ranking well" even means — being cited as a source within an AI overview is an increasingly important, distinct form of visibility from a traditional blue-link ranking.
In a sentence
"Traffic from that keyword dropped noticeably after an AI overview started appearing at the top of the results page, even though our organic ranking position didn't actually change."
