AI Overviews

AI Overviews are AI-generated summaries that appear at the top of some Google search results. They answer the query in a few paragraphs or bullet points and include links to the web pages used as sources. Launched widely in 2024 after testing as the Search Generative Experience (SGE), they now appear for a large share of informational searches.

How AI Overviews work

Google uses its Gemini models together with its search index. For a given query, it finds relevant, high-quality pages, extracts the most useful information and writes a summary. Source links appear alongside or within the overview. Google tends to show AI Overviews for complex or multi-part questions, and less often for simple navigational or highly commercial searches.

How AI Overviews affect SEO

  • Fewer clicks for simple questions: when the summary fully answers the query, fewer people click any result (Zero-Click Searches).
  • New visibility opportunity: being cited in an overview puts your brand at the top of the page, sometimes above the first organic result.
  • Different sources: Google may cite pages that are not in the top organic positions if they answer a specific part of the question well.
  • Changing click-through rates: organic results below an overview often see lower CTR, which makes titles and descriptions even more important.

How Google chooses sources

Google has said there is nothing special required to appear in AI Overviews beyond normal SEO best practices. Pages must be indexed and eligible to show a snippet. In practice, frequently cited pages:

  • Rank well for the query or related sub-queries.
  • Answer specific questions clearly and concisely.
  • Are well structured with descriptive headings.
  • Come from trusted, authoritative sources (E-E-A-T).
  • Provide information that adds to what other sources say.

How to optimise for AI Overviews

  1. Target question-based and complex queries where overviews appear.
  2. Lead each section with a direct answer, then add detail (Answer Engine Optimisation (AEO)).
  3. Cover related sub-questions on the same page, since overviews often combine several.
  4. Use lists, steps and tables where appropriate.
  5. Keep facts accurate and current.
  6. Build authority through links, mentions and expertise.
  7. Avoid nosnippet restrictions on pages you want to be cited.

Tracking AI Overview visibility

Google Search Console includes AI Overview impressions and clicks within normal search performance data, without a separate filter. Use rank tracking tools that record AI Overview appearances and citations, and watch for changes in impressions and CTR on question-based queries.

Should you worry about AI Overviews?

They change which searches bring clicks, but they do not remove the value of SEO. Commercial and local searches, complex decisions and brand searches still drive visits. Focus on topics where your expertise adds real value, and treat citations as brand exposure. For Google’s more conversational AI experience, see Google AI Mode.
