AI Overviews rewrite the search landscape and force publishers to adapt
AI Overviews in the Google results are changing more than aesthetics. They change who wins attention by assembling full answers in the search engine results page and by surfacing related subtopics and refinements that guide decision making. That is the central argument in a recent analysis by Natasha Post for Search Engine Land, which sets out how Google query expansion and the newer query fan-outs used for AI answers now work together to reshape visibility online.

AI Overviews create new winners and losers
Where once the search results were dominated by a handful of blue links, now Google can generate an AI Overview that reads like a short article. Those overviews do more than answer a single query. They pull in related terms, supporting facts and contextual refinements that help a user decide what to click next or whether to click at all. For publishers that rely on organic traffic, the consequence is stark. Ranking first for a keyword no longer guarantees inclusion in the AI answer, and being excluded can cost significant traffic.
What Google query expansion actually does
Query expansion is not new. Its purpose is practical: stop long tail or oddly phrased queries returning nothing by broadening a user query to include synonyms, intent signals and related topics. In practice that looks like Google treating budget and affordable as similar, recognising a question-form intent even without explicit question words, or surfacing pages that are semantically relevant even when the exact phrase is absent.
Publishers can confirm these behaviours in Google Search Console by inspecting the query list for a page and looking for unexpected impressions and related query forms. That process surfaces the organic signals Google is already using and highlights opportunities to add concise sections that satisfy those expanded queries. Google Search Console is the place to start when auditing which query expansions are already pulling traffic to your pages. https://search.google.com/search-console/about
Query fan-outs: the AI Mode difference
Query fan-outs are a separate but related phenomenon. When Google or other LLM-driven systems operate in AI Mode, a single user query can be split into multiple subqueries while the answer is generated. Those subqueries are then used to retrieve supporting sources that the AI synthesises into the final Overview. In short, query expansion broadens before results are generated in traditional search; query fan-outs break a query apart during AI answer creation. The same semantic relationships that cause expansion in classic search can therefore determine which pages are picked up as sources for AI Overviews.
Practical steps publishers can take now
1. Use Search Console methodically
– Filter Performance by page and pull the full query list sorted by impressions. Look for synonyms, question-formed queries and broader keywords you did not target. If those queries are relevant, add concise, factual sections to your page to satisfy them.
2. Write for topic coverage not keyword density
– Build subtopics, related questions and adjacent content that show clear semantic coverage. This is not permission to keyword stuff. It is an instruction to cover the actual experience a reader expects when they click through.
3. Treat AI Overviews as a placement to earn
– Cross-reference the supporting topics found in query expansions with the main SERP keyword. If AI Overviews for that keyword commonly include those subtopics, add short, well-sourced blocks to your article that answer them directly. That increases the chance your page will be used as a source during query fan-outs.
4. Audit quarterly and keep content modular
– New queries will appear and others will fade. Quarterly checks let you prioritise edits and avoid bloating pages. Modular sections are easier to update and to surface in AI-driven summaries.
5. Use external tools wisely
– Tools such as Semrush and Ahrefs can help map semantic relationships and visibility in AI search, but they are a supplement not a substitute for the ground truth in Search Console. Consider using an AI visibility product to monitor presence in AI Overviews alongside your GSC data. https://www.semrush.com/ai-seo/overview
Examples that make the point
Simple examples illustrate why this matters. A page about backyard chicken care that never uses the word lifespan can still rank for queries about average chicken life if Google deems it semantically relevant. Similarly, a post on tandem versus spread axles might rank first for the phrase tandem truck meaning without containing that exact wording. In both cases, adding a short, focused section on the missed phrase improves both traditional ranking relevance and the chance of inclusion in an AI Overview.
What this means for Irish publishers and brands
For Irish businesses and media the implications are practical and strategic. On the practical side, SEO teams must pivot from narrow keyword campaigns to easily digestible topic coverage that addresses adjacent questions. On the strategic side, an uncomfortable truth emerges: platform-driven summaries shift attention away from direct publisher engagement and towards the snippet itself. That raises questions about dependency on a single gatekeeper and about the long term value of chasing SERP features rather than building direct customer relationships and first party channels.
A note of commercial caution
There is a political economy to this shift. Firms with the budgets to monitor AI visibility, hire technical SEO expertise and update content at scale will gain advantage. Smaller outlets should not be paralysed. The simplest, most cost effective moves – auditing Search Console, adding a handful of targeted sections, and prioritising factual clarity over cleverness – deliver disproportionate returns. Irish companies that treat this as an operational challenge rather than a marketing mystery will be better placed to protect and grow their organic reach.
Conclusion
Google query expansion and AI-driven query fan-outs are two sides of the same semantic coin. The practical response for publishers is straightforward: measure, fill genuine gaps, avoid keyword stuffing and make it easy for AI systems to see your content as a reliable source. Natasha Post set out these dynamics clearly in her Search Engine Land piece and the implications are now business critical for anyone who depends on search to acquire customers. For editors and marketers in Ireland the immediate task is not to chase every shiny feature but to ensure that the content you own answers the expanded queries Google is already serving.
