How Fan-Out Query Coverage Boosts Your Odds of Being Cited in Google AI Overviews

Google’s AI Overviews are reshaping visibility opportunities in search by citing pages that offer depth across related queries — not just the highest-ranked pages for a single keyword. A recent analysis reported by Search Engine Land, based on Surfer SEO’s research, shows a strong connection between ranking for “fan-out” queries and earning citations in AI Overviews.

What the Surfer SEO analysis found

Surfer SEO’s large-scale study examined fan-out behavior and AI Overview citations across tens of thousands of queries. The headline findings are clear: pages ranking for fan-out queries are far more likely to be cited. Key statistics from the analysis include:

• Pages ranking for fan-out queries are 161% more likely to be cited than pages that rank only for the main query.
• There is a strong Spearman correlation of 0.77 between the number of fan-out queries a page ranks for and its likelihood of being cited in AI Overviews.
• 76% of the sampled keywords triggered AI Overviews in the data set.
• Surfer extracted approximately 33,000 fan-out queries for the study.
• Pages ranking for both the main query and at least one fan-out accounted for 51% of AI Overview citations.
• Roughly 68% of cited pages did not appear in the top 10 organic search results, showing citations frequently come from outside traditional top-ranked positions.

As Search Engine Land summarizes, “If you want to be cited in Google AI Overviews, don’t chase fan-out queries. Own the topic.” That emphasis — on owning the topic rather than gaming individual keywords — is the study’s practical takeaway.

Why fan-out coverage matters to AI Overviews

AI Overviews synthesize information, pulling together concise answers from multiple sources. These systems value depth and diversity of content because they need context to craft trustworthy, useful summaries. A page that addresses multiple subtopics and related questions provides the semantic richness AI models use to identify authoritative citations.

Importantly, the study shows citation selection does not strictly follow SERP rankings: many cited pages are not in the top 10. That means sites can obtain valuable visibility through AI Overviews even when they’re not dominating traditional rankings.

Actionable tactics to increase citation odds

Below are practical steps you can implement to increase the likelihood your pages will be cited in AI Overviews.

1. Build topic clusters, not standalone pages

Create hubs that cover a core subject and link to supporting pages addressing related subtopics. Use pillar pages with clear navigation and internal links so search engines and AI systems can see the full breadth of your coverage.

2. Use clear answer blocks and FAQ sections

Format content with concise, direct answers to common questions. Short, standalone answer paragraphs or FAQ blocks help AI extract precise snippets for citations.

3. Employ semantic headings and structured layout

Use descriptive H2s and H3s that align with user questions and fan-out variants. Well-structured content reduces ambiguity and aids AI in locating the most relevant passages.

4. Add authoritative citations and references

AI models favor trustworthy sources. Cite reputable studies, official documentation, and domain-relevant authorities. Proper citations boost the credibility signals AI systems rely on.

5. Implement schema and structured data

Schema markup (FAQ, HowTo, Article) communicates the type of content and its subcomponents, making it easier for AI extraction tools to interpret and reuse your content in Overviews.

6. Strengthen internal linking and topical signals

Internal links connect related content and pass topical relevance throughout your site. That network effect helps pages rank for multiple fan-out queries and signals breadth of coverage.

7. Monitor fan-out variation and personalization

Fan-out queries can vary by user context and personalization. Track which fan-outs appear repeatedly in AI Overviews and prioritize content expansion for the most consistent variants.

8. Measure citations, not just rank

Because many citations come from pages outside the top 10, set up tracking for AI Overview citations and referral traffic from those snippets. Use a mix of tools and manual checks to capture citation occurrences.

Conclusion

The Surfer SEO study — reported by Search Engine Land — shows that thorough topical coverage across fan-out queries is a practical path to earning citations in Google’s AI Overviews. Rather than targeting single head terms, prioritize structured, answer-focused content, authoritative references, and internal topic networks. Those steps increase your odds of being discovered and cited by AI-generated summaries, delivering visibility even when traditional rankings are limited.
