Google AI Overview: what exactly is it?
Google AI Overview (formerly Search Generative Experience, SGE) is an AI response generated directly within Google search results. It appears above classic organic results, in a distinct box, and synthesises a response from multiple web sources.
In practice, when a user searches for "best CRM for SMEs in 2026", Google no longer simply lists links. It generates a structured response comparing the options, with links to the sources used. The user gets their answer without clicking on any link.
This is the most radical change in Google's history. Since 1998, Google was an intermediary that redirected to sites. Now it is itself the destination. And this changes everything for your company's AI visibility.
Data from Sistrix (Bonn, Germany) is clear: in Europe, AI Overview appears on 47% of commercial queries and 62% of informational queries as of early 2026. The trend is upward.
The impact on your organic traffic
Let us be direct: AI Overview redistributes traffic. And not in your favour if you are not cited in it.
| Situation | Impact on CTR | Impact on traffic |
|---|---|---|
| Cited in AI Overview (source #1) | +35% CTR vs classic position 1 | Significant increase |
| Cited in AI Overview (sources #2-5) | CTR comparable to classic positions 1-3 | Stable or slight increase |
| Organic position 1 but NOT in AI Overview | -25% to -40% CTR | Significant drop |
| Organic positions 2-10 without AI Overview | -40% to -60% CTR | Collapse |

The message is clear: if you are not in AI Overview, you are losing traffic even if you are well-positioned. And if you are in it, it is a considerable boost. This is the biggest redistribution of visibility since the introduction of featured snippets.
Stefan Fischerlaender, senior SEO consultant at Onpage.org (Munich), sums it up: "AI Overview is an absolute game-changer. Companies that do not adapt will see their organic traffic melt away progressively, even with perfect technical SEO."
Google AI Overview selection criteria
Google AI Overview draws its sources from the classic Google index. This is the major difference from ChatGPT (Bing) or Perplexity (multi-source). To appear in AI Overview, you must first be well-positioned in Google. That is the prerequisite.
But classic Google ranking is not enough. Here are the additional factors:
1. Directly answerable content
AI Overview extracts text blocks that directly answer the query. If your page covers the topic but does not provide a direct and concise answer, it will not be selected.
2. Reinforced E-E-A-T
Experience, Expertise, Authoritativeness, Trustworthiness. Google applies these criteria even more strictly for AI Overview. Pages with identified authors and visible credentials are preferred. Consult our guide on AI visibility for the fundamentals.
3. Structured data
Schema.org FAQPage, HowTo, Article, Product -- structured data helps Google understand and extract your content for AI Overview.
4. Multi-perspective coverage
AI Overview synthesises multiple sources to give a balanced response. Content that covers pros and cons, alternatives, and nuances is preferred.
5. Freshness and updates
Recently updated content is preferred, especially for time-sensitive queries ("in 2026", "latest version").
Practical optimisations to appear in it
Here is the checklist we deploy at AI SOS for our clients:
Impeccable classic SEO. Before thinking about AI Overview, ensure your Google SEO is solid. Page speed, mobile-first, HTTPS, internal linking, quality backlinks. AI Overview draws from the Google index: if you are not well-indexed, you do not exist for AI Overview.
Direct answers under each H2. Start each section with a concise answer in 2-3 sentences. AI Overview extracts these blocks. This is the most impactful technique.
Comparison tables. For comparative queries ("A vs B", "best X"), a comparison table is near-mandatory. AI Overview loves tables.
Structured FAQ at the bottom of the page. With Schema.org FAQPage markup. FAQ questions often correspond to Google's "People Also Ask", which feeds AI Overview.
Stacked structured data. Article + FAQPage + Organization (or Person for the author). The more Google understands your content, the more it can exploit it.
Minimum quarterly updates. Each strategic piece of content must be reviewed and updated at least every 3 months. Add a visible update date.

FAQ
Is Google AI Overview available in Europe?
Yes. Google AI Overview is available across Europe and progressively appearing on more queries. By end of 2025, it was present on approximately 47% of commercial queries in English (source: Sistrix).
Can you disable Google AI Overview?
Users can in some cases collapse the AI Overview response, but cannot disable it completely. For webmasters, it is not possible to prevent content from appearing in AI Overview while remaining in the Google index. It is all or nothing.
Will AI Overview kill SEO?
No, but it profoundly transforms it. Classic SEO remains the prerequisite for feeding the index AI Overview uses. But SEO alone is no longer enough. You need to combine SEO + AEO to maintain and develop your visibility in the Google ecosystem.
Do you need to be in position 1 to appear in AI Overview?
No. Sistrix studies show that sites at positions 5-10 can be cited in AI Overview if their content better addresses the specific query. Direct relevance takes precedence over classic position, even though well-ranked pages have a statistical advantage.
Are AI Overview and featured snippets the same thing?
No. Featured snippets extract a block of text from a single source. AI Overview synthesises a response from multiple sources and generates original text. The two coexist, but AI Overview tends to replace featured snippets on a growing number of queries.
How do you know if AI Overview appears on your keywords?
Test manually in private browsing, or use tools like Sistrix and Semrush that indicate the presence of AI Overview in their keyword reports. The volume of queries with AI Overview increases every month, so check regularly.
Conclusion
Google AI Overview is the biggest evolution in Google search since featured snippets. And unlike featured snippets, the impact is massive: 47% of commercial queries, with an upward trend.
If you are cited, it is a huge growth lever. If you are not, it is a silent traffic haemorrhage. There is no middle ground.
The rules have changed. Google AI Overview is the new battleground.
