Let's get started.
Summary
What is fan-out in Google search results?
Fan-out is a concept introduced by Google in March 2025 with AI Mode, an extended version of AI Overviews. Concretely, the algorithm no longer just answers your initial query: it "deploys" answers to related questions you haven't asked, but which might interest you.
For example, if you are looking for the best smartwatch for sleep tracking, the AI could also explain heart rates during sleep. This approach is part of semantic search, where intent takes precedence over exact keywords.
For a merchant, this means your content must cover not only the main subject, but also the facets surrounding it. This is an opportunity to answer questions your customers ask without formulating them. By anticipating these needs, you position your store as a reference in your niche, which builds user trust and improves your credibility in the eyes of Google.

Why is fan-out a game-changer for e-commerce SEO?
Fan-out changes the way Google selects sources for its generative responses. If your content only addresses the main topic, it risks being ignored in favor of an article that also addresses satellite questions. For an e-commerce site, this is crucial: your product pages and blog posts must anticipate related needs.
Let's take an example: a customer is searching for "maintenance cost of a website". A fan-out response could include "hosting cost", "SSL security cost", or "content update cost". If your page does not cover these aspects, you lose a chance of being cited.
By integrating these sub-themes, you improve your relevance in Google's eyes and better meet user expectations, which can increase your click-through rate and conversions. Furthermore, this approach allows you to stand out from competitors who content themselves with only addressing the main topic, thereby offering you a sustainable competitive advantage.
How to use Gemini to generate relevant sub-queries?
Gemini, Google's AI chatbot, is a powerful tool for identifying sub-queries related to your main topic. Start by collecting your existing keywords, for example via Search Console or a keyword research tool. Export them to a CSV file.
Next, upload this file to Gemini with a prompt like: "Here is my list of target keywords. What are the sub-queries or facets related to these topics?" The AI will generate structured lists of related questions, such as for "website maintenance cost": recurring costs, factors influencing costs, importance of maintenance, types of maintenance, solutions and services, comparisons between platforms.
This approach helps you expand your content systematically, without having to guess what your prospects are searching for. By automating this research phase, you save precious time and ensure you do not overlook any important facet of your topic.
How to refine your prompts with Gemini to anticipate Google's expectations?
To refine your prompts, enable the "Show thinking" option in Gemini 2.5 Pro. This feature reveals the AI's reasoning, allowing you to understand how it processes your topic. For example, for a query about buying designer shoes online, Gemini showed that it focused on "try before you buy" programs, return policies, and return shipping fees.
By following this logic, you can anticipate the criteria that Google considers important for a given query. For your shop, this means you must not only sell products, but also provide information on return policies, try-on options, and price comparisons.
This analysis gives you a head start in creating content that meets users' implicit expectations. By understanding the AI's reasoning, you can also adjust your content strategy in real time, in response to changes in Google's algorithms.
How to structure your content to answer secondary questions?
Once your sub-queries are identified, organize your content into clear sections that address each facet. For example, for an article on maintenance costs, create dedicated sections for recurring costs, cost factors, types of maintenance, and available solutions.
Use section headings in the form of questions, such as "How much does website hosting cost?" or "What are the hidden costs of maintenance?". This helps Google understand the structure and extract snippets for AI Overviews.
Ensure that each section provides a concise and useful answer, with bulleted lists if necessary. This improves user experience and increases your chances of being cited in fan-out answers. A clear structure also makes navigation easier for your visitors, encouraging them to explore your site further.
Why does keyword research remain essential in the face of fan-out?
Even with AI, keyword research remains fundamental. The words and phrases your prospects use reveal their needs and buying journey. By optimizing these keywords, you increase your chances of being cited as a source in AI Overviews and AI Mode.
Fan-out does not replace keyword research; it enriches it. You still need to identify the main terms, but also the variations and related questions. For example, for "website maintenance cost", sub-queries include "hosting cost", "security cost", "update cost".
By integrating these variations into your content, you cover a broader spectrum of queries, which improves your overall visibility. Furthermore, this approach allows you to remain relevant in the face of changing search behaviors, adapting to the new ways users formulate their questions.
How to optimize your product pages for fan-out?
Your product sheets can also benefit from fan-out. For each product, identify the questions that customers ask themselves: "What is the lifespan of this product?", "Is it compatible with other accessories?", "What are the delivery options?". Integrate these answers into the description or into a FAQ section.
For example, if you sell smartwatches, add information about sleep tracking, heart rate, and battery life. This allows Google to cite you for related queries, even if the user did not explicitly ask these questions.
This approach improves the customer experience and strengthens your topical authority, which is beneficial for long-term SEO. By providing complete answers directly on your product sheets, you also reduce the bounce rate and increase the time spent on your site.
How to use Search Console to discover queries associated with your pages?
Search Console is a valuable tool for discovering the queries that users associate with your pages. Go to "Performance" > "Queries", then filter by URL to see the terms that generate impressions and clicks. Export this data to CSV for analysis.
These queries can reveal facets you hadn't considered. For example, for a page on maintenance costs, you might discover queries like "WordPress maintenance cost" or "Shopify maintenance cost". Integrate these variations into your content.
By using this data, you refine your content strategy and ensure you cover the topics that truly interest your audience. This method, based on concrete data, allows you to prioritize your efforts and optimize the pages with the highest traffic potential.
How to address multiple intents within the same content?
Fan-out requires addressing multiple intents within the same content. For example, an article about maintenance costs must not only provide figures, but also explain why maintenance is important, what the risks are of not performing it, and how to choose a maintenance service.
Structure your article into sections that address each intent: costs, benefits, types of maintenance, and solutions. Use concrete examples and lists to make the information digestible.
This holistic approach increases your chances of being cited in fan-out answers, as you cover a wide range of related questions. By addressing all of your readers' potential concerns, you help them make an informed decision, which strengthens their trust in your brand.
How to measure the effectiveness of your strategy against fan-out?
To evaluate the effectiveness of your strategy against fan-out, track your performance in Search Console. Monitor impressions, clicks, and average position for target queries. Compare these metrics before and after optimizing your content.
Also use Google Analytics to analyze user behavior: time spent on page, bounce rate, conversions. If you notice an increase in organic traffic and conversions, it means your content is meeting expectations.
Don't forget to monitor AI Overviews: if your page is cited, you will see an increase in impressions for related queries. By regularly analyzing this data, you can continuously adjust your strategy and maximize your return on investment.
