Short answer
There is no separate submission for AI Overviews. Google builds them from pages that are indexed and eligible to appear in Search. To show up, rank well for the question, answer it directly near the top of the page, structure the content with clear headings and lists, and make sure Googlebot can crawl and index the page.
Google has said there are no extra technical requirements for AI features beyond normal Search eligibility. In practice, the pages cited most often share a few traits:
- They rank already. Pages on the first page of results for a query are far more likely to be used as a source.
- They answer fast. The answer sits in the first paragraph under a heading that matches the question.
- They are easy to lift. Steps are numbered, comparisons are in tables, definitions are one or two sentences.
- They show expertise. Specific examples, data and a clear author or publisher build trust.
- They are current. Facts and dates are kept up to date.
One common mistake: blocking Google-Extended in robots.txt does not remove you from AI Overviews. That setting controls whether Google uses your content to train Gemini models, not whether you appear in Search.
