AI Overviews draw mostly from pages that already rank well in Google, so if you are not on page one for the underlying query you are rarely in the Overview. The common misconception is that Google-Extended controls this. It does not. It governs Gemini, not AI Overviews inclusion.

The short version

Why this happens

AI Overviews are built on Google’s existing index rather than a separate one. That has a blunt practical consequence: if you do not rank reasonably well for the query underneath the Overview, you will rarely be drawn into it. Analyses consistently find a large majority of cited URLs already ranking on page one.

So the first diagnostic question is not about AI at all. It is whether you rank. If you do not, your AI Overview problem is a conventional SEO problem wearing a new hat, and the fix is the unglamorous one.

If you do rank and are still absent, the cause is usually extraction. Overviews assemble an answer from several sources, each contributing a piece. They favour passages that answer a specific sub-question in a self-contained way. A page can rank first and contribute nothing, because nothing in it stands alone as an answer to any of the sub-questions the Overview is composing.

Now the misconception, and it is worth being precise because it costs people visibility. Many firms added Google-Extended to robots.txt believing it controlled AI Overviews. It does not. It governs whether your content is used for Gemini training and grounding. AI Overviews inclusion is tied to ordinary Google Search indexing, and there is no separate opt-out that keeps you in Search but out of Overviews. Blocking Googlebot removes you from both, which is almost never what anyone wants.

There is also a measurement trap here. A page can appear in an Overview, be read by the user, and generate no click at all. On a CTR report that looks like failure. It is frequently the opposite: you were cited, the buyer got the answer, and your brand was the one attached to it.

How to check it yourself

  1. Search your target query in Google with a UK location and see whether an Overview appears at all. Not every query triggers one.
  2. If it does, read the cited sources. Are you there? Who is?
  3. Check your classic ranking for the same query. If you are not on page one, that is the constraint.
  4. Check robots.txt for an over-broad Google-Extended or Googlebot rule added in the last two years.
  5. In Search Console, look for pages with high impressions, good average position and almost no clicks. That pattern often indicates an Overview answering in place, which is worth knowing before somebody calls it underperformance.

What to do about it

  1. Fix ranking first where you do not rank. There is no shortcut around this one.
  2. Restructure so each section answers one sub-question cleanly, in a way that stands alone.
  3. Review your crawler rules and remove any that were added on a misunderstanding.
  4. Change how you report. Track citation presence, not just clicks, or you will conclude the work failed when it worked.
  5. Use FAQ structure where it genuinely fits the content, because it maps well onto how Overviews decompose a question.
