Key takeaways

  • A page can be a supporting link in AI Overviews or AI Mode only if it is indexed and eligible to show a normal Search snippet; meeting that bar still does not guarantee selection.
  • No special schema, AI text file or markup is required, and any structured data must match the visible content.
  • Google finds sources with retrieval from its Search index plus query fan-out, which splits one question into subtopics searched at the same time.

  • Citations and clicks are separate outcomes: in Pew Research Center's data, people clicked a link inside an AI summary in only 1% of visits.
