Google’s AI Overviews do not appear for every search. According to Ahrefs data, they show on 21% of all keywords but on 57.9% of question queries. That gap is important. It tells you which content is most exposed to AI summarisation and where the opportunity to appear inside an overview is greatest.
If your site answers questions, more than half of those queries may already trigger an AI Overview. The question is whether your content is the source Google uses to build it.
Why question queries dominate
Question queries are natural territory for AI Overviews because the user is asking for an explanation, a list, or a recommendation. “What is…”, “How do I…”, “Should I…” and “Why does…” all invite a synthesised answer. Google is confident enough to provide one directly, often with citations.
For marketers, this means your FAQ, how-to and explainer content is now operating in a different competitive environment. You are no longer just competing with the ten blue links. You are competing to be the source that shapes the summary.
What the data suggests about optimisation
Pages that appear in AI Overviews tend to give clear, direct answers early in the content, then expand with detail. The overview can extract the concise answer while the full page remains available for users who want depth.
Structured markup, clear headings, and factual precision all help. If your page contradicts itself, buries the answer, or uses vague language, it is less likely to be selected as a citation source.
Authority also matters. Google appears to prefer sources it already trusts for a topic. A site with strong topical coverage, good backlinks and consistent expertise is more likely to be cited than a one-off page, however well written.
Turning the data into a plan
Start by identifying your question-query content. Use Search Console, keyword research tools, or your own site search logs to find the pages that answer “what”, “how”, “why” and “should” questions.
For each page, ask:
- Is the answer obvious within the first paragraph or section?
- Are the facts current and specific?
- Is the page supported by related content that shows topical authority?
- Does the structure make it easy for a machine to extract a summary?
Then track whether AI Overviews appear for those queries and whether your site is cited. This is a new visibility metric, but it is where question-query SEO is heading.
A realistic expectation
Appearing in an AI Overview is not the same as ranking first. A page can be cited without being the top traditional result, and a top result can be ignored by the overview. The two systems overlap but are not identical. Optimising for both is the sensible approach.
