AI Overviews replace the old "ten blue links" with a written answer for many informational queries, and the scale is no longer a side experiment: Google said at I/O in May 2026 that AI Overviews passed 2.5 billion monthly users. They cite a handful of sources alongside the summary, and those citations are the visibility you compete for.
Appearing in an AI Overview is less about domain authority than about being the clearest, best-structured answer to the question. Google's own guidance states there is no special markup required to be eligible; standard helpful-content practices apply.
