Google AI Mode and query fan-out: why one strong page is no longer enough for SEO
This topic has a very clear and official source. On March 5, 2025, Google released the material Expanding AI Overviews and introducing AI Mode and for the first time, she explained quite directly how exactly she sees the new search mode. Not only the AI Mode itself is important there, but also the wording about query fan-out: The system runs multiple related searches across subtopics and sources and then compiles them into a single answer.
Для SEO это меняет саму механику борьбы за видимость. Если раньше оптимизатор чаще думал в логике "запрос -> страница -> позиция", то теперь приходится думать шире: "задача пользователя -> поднамерения -> кластер источников -> follow-up вопросы -> путь к сайту".
Article focus: query fan-out and related materials architecture. For a technical checklist for Google AI Overviews and AI Mode, go to practical plan; Here we are only looking at why one strong page is not enough.
What Google itself says about AI Mode
B first announcement of AI Mode Google directly writes that the mode is designed for complex, compound questions, comparisons and follow-up scenarios. This is an important shift. Search stops pretending that the user always comes with a short and already perfectly formulated query.
Google later expanded the picture. In April 2025 in announcement of multimodal search in AI Mode the company showed that the mode understands not only text, but also images as part of the request. And in May 2025 in the material AI in Search: Going beyond information to intelligence it became clear that AI Mode is moving further towards deeper and more agent-based work with the issue.
If you translate all this into SEO language, the picture is simple: Google wants less and less to simply match a key phrase with a page and more and more wants to take the user's task apart.
What is query fan-out in simple words?
Imagine that a person asks not “the best CRM for an agency,” but something longer: which CRM is suitable for a real estate agency if it needs integration with WhatsApp, funnel control, working with brokers and clear analytics. Previously, for such a question, the user would have done several searches in a row. Now AI Mode takes on part of this work.
Query fan-out means that the search does not rely on one line as the only source of meaning. It splits the task into several directions, pulls data in parallel and only then collects the answer. This is why one well-optimized page is increasingly not enough.
Why is one strong article not enough?
This is unpleasant news for sites that are accustomed to living on the scheme “we made one big turnkey material and are waiting for traffic.” In the world of AI Mode this is not enough for two reasons.
Firstly, the user's question is divided into subparagraphs. This means that you must have answers not only to the main intent, but also to neighboring questions.
Secondly, AI Mode loves follow-ups. The user does not stop at the first answer, but deepens the topic. If a site can only close the top layer of a request, it becomes only partially useful.
What does this mean for content strategy?
1. We need clusters rather than single pages
Now what is more important is not just one “ideal article”, but a set of materials that covers the topic from several sides: explanation, comparison, FAQ, cases, adjacent scenarios, clarifying questions.
2. The structure of the answer becomes more important
Lists, subheadings, definitions, short blocks “what is it”, “when to use”, “what are the risks”, “what to do next” are needed not only by the user. Such structures are easier to pick up and integrate into a multi-step AI response.
3. Freshness and essence cannot be ignored
Already in announcement of AI Mode Google specifically mentions fresh, real-time sources, Knowledge Graph and shopping data. This means that for some topics, relevance, clear essence and good coherence between pages are critical.
What should an SEO team do right now?
Rebuild the audit not around keys, but around tasks
It’s worth checking not only positions and CTR, but also whether the site can close a complex user scenario. Where do you have a full-fledged cluster, and where is a lonely page that hangs without support.
Strengthen pages that really explain the topic
In AI search, materials that do not revolve around a key phrase, but properly explain the subject, work better. If the text is filled with general words and does not provide clear supporting blocks, it is poorly suited to both the person and the AI system.
Divide content into depth levels
Some materials should quickly answer the starting question. Others want to analyze the topic in depth. The third is to close clarifying questions. In this sense, good information architecture begins to resemble the logic of AI Mode itself.
Which metrics are now more useful?
Looking only at classic positions is already risky. It's more useful to add:
- visibility by thematic clusters;
- covering FAQ and comparison intent;
- share of pages that close follow-up questions;
- change in CTR with the growth of AI surfaces;
- speed of content updating in rapidly changing topics;
- share of branded and non-branded paths to the site.
It is these metrics that better show how compatible the site is with the new search logic.
Why this article is also useful for SEO
There is direct demand here: Google AI Mode SEO, query fan-out Google, как оптимизировать сайт под AI Mode, AEO для Google, AI search SEO. But a good text on this topic should not scare with big words, but explain a very practical thing: in AI search, sites that cover the user’s task more broadly and clearly win.
For NBM this is directly related to integration of AI into business processes: if a client wants not just to write articles, but to build stable visibility in AI search, he needs not a scattering of texts, but a managed system of clusters, updates and connections between pages.
