Google AI Overviews are the AI-generated summaries at the top of many results, built from pages Google has already indexed. To be cited, your page must be indexed, eligible for snippets, genuinely helpful, and easy to extract. Google is clear that there is no separate optimisation: it is standard SEO plus clear, textual, well-structured content.
What are AI Overviews?
An AI Overview is a short, AI-generated answer Google places above the classic blue links for many queries, with links to the sources it drew from. It is one of several AI answer surfaces, so it helps to understand the wider picture first: see what Answer Engine Optimisation is and how AEO differs from SEO. Crucially, Overviews are assembled from Google's existing index, not a separate one, which is why normal SEO eligibility is the entry ticket.
How does Google pick its sources?
Google's own documentation on AI features and your website lays out what matters, and it is refreshingly ordinary:
- The page is indexed and eligible for standard Search snippets.
- The content is helpful, reliable and people-first, not made to game rankings.
- Important content is in textual form, not locked inside images or scripts.
- Internal linking is strong and the page experience is good.
- Structured data is present and accurate.
Trust is the deciding factor. Google's guidance on people-first content calls trust the most important part of E-E-A-T and asks who created the content, how, and why, which is why a named author and transparent sourcing help.
How do you get cited?
Eligibility gets you considered. These steps make you the passage Google actually lifts:
- Confirm the page is indexed and not blocking snippets (no stray nosnippet or data-nosnippet).
- Answer the query directly in the first 40 to 60 words, then expand.
- Keep the answer in real text, and make sure it is server-rendered so crawlers see it without running JavaScript.
- Use H2 and H3 headings that match how people phrase the question.
- Turn comparisons into tables and processes into numbered steps.
- Back claims with dated figures and cite the primary source.
- Show a named author, a visible last-updated date, and keep the page fresh.
- Do not waste time on AI-only files. Google explicitly says you do not need to create AI text files or special markup.
How do you make sure Google can read you?
None of this works if Google cannot crawl the page. Allow Googlebot in robots.txt, and remember that AI Overview eligibility rides on normal indexing, so blocking Googlebot removes you from both. A separate crawler, Google-Extended, controls whether your content is used to train and ground Gemini models; you can allow or block it in robots.txt independently, without affecting your normal Search and AI Overview eligibility. And if your key content only appears after JavaScript runs, many crawlers never see it, so keep the answer in the server-rendered HTML.
How do you measure it?
Google Search Console reports AI Overview performance under the Web search type, so you can watch impressions and clicks. For brand-level tracking, Limecube's AI Overview report checks each keyword you track and records whether an Overview appeared, whether it named your brand, whether it cited your domain and at what position, and which competitors were mentioned, alongside your Search Console clicks for the same term. The features tour shows the full report, and pricing starts with a 7-day trial.
