What are AI Overviews – and why do they change everything?

Since Google rolled out AI Overviews (AIOs), many users searching for certain queries no longer see the familiar blue links first – instead they get a AI-generated summary directly on the search results page.

The scale of this shift is substantial: according to analysis from December 2025, 794 of the top 1,000 “What is” queries in the US triggered an AI Overview. For local searches the picture is different – of the top 1,000 “Roofing company in” queries, only 5 had an AIO. This shows that AIOs don’t affect every industry equally.

The zero-click reality

Zero-click means: the user asks a question, gets the answer directly on the Google page – and doesn’t click on any website.

This effect is real and growing. For informational queries (“What is…?”, “How does…?”, “Why…?”) it’s particularly pronounced. For transactional queries (“performance marketing agency Stuttgart”, “get a website built”), the impact so far is significantly lower.

For SMEs, this means a reassessment of content strategy: purely informational articles that previously drove organic traffic now compete directly with AI summaries. Traffic doesn’t go to zero – but it declines.

The good news: being cited as a source in these AI answers creates a new form of visibility that’s often more qualified than a regular click. A user who clicks a cited link within an AIO already has a concrete intent.

What the Ahrefs study reveals – why top rankings are no guarantee

An Ahrefs analysis from August 2025 examined the relationship between classical SEO rankings and AI citations. The results are surprising:

  • The correlation between a top-10 ranking and a top-3 AI citation is just 0.347 – weak to moderate
  • Websites ranked #1 on Google appear prominently in AI results only ~50% of the time
  • 80% of AI citations come from pages not in Google’s top 100
  • Only 12% of URLs cited by ChatGPT, Gemini and Copilot appear in Google’s top 10

What follows? The game has changed. A high Google ranking is no longer an automatic path to AI visibility – and conversely, even without a dominant SEO profile, a page can be regularly cited by AI systems if it has the right quality characteristics.

What AI systems actually prefer

AI systems prioritise content with characteristics that go beyond pure keyword density:

Unique data and insights Your own case studies, survey results, practical experience or comparisons that can’t be found elsewhere. AI models actively seek out sources that go beyond their training data.

Clear, structured answers FAQ blocks with naturally phrased questions and short, precise answers are frequently taken directly as citations.

Authority through external signals Mentions in industry media, partner backlinks and consistent company data (name, address, services) increase the trust AI systems place in a business.

Schema markup FAQPage, HowTo and BlogPosting help AI crawlers categorise content faster and more accurately.

The opportunity for specialised SMEs

The Ahrefs data contains a hidden opportunity: if 80% of AI citations come from outside the top 100, then AI visibility is not a privilege of large websites with massive backlink profiles.

What counts is relevance, structure and a unique perspective. This is the strength of specialised agencies and SMEs with deep industry knowledge. A commercial cleaning company from Villingen-Schwenningen that explains in detail what professional cleaning costs in commercial properties – and what to look for – can collect more AI citations on that topic than a generalist mega-portal.

Strategy: How to optimise for AI citations

Step 1: Identify unique content What knowledge do you have that others don’t? Your own figures, practical experience, case studies – that’s the foundation.

Step 2: FAQPage schema on all service pages For each core service: answer 3–5 real customer questions. A good FAQ question sounds like: “What does a website for a small business cost in 2026?” – not: “Web design pricing”.

Step 3: Timestamp your data “As of Q1 2026” signals AI systems about recency. Outdated data without a time reference gets cited less often.

Step 4: Update dateModified in schema When an article is updated, this should be visible in BlogPosting schema. It signals active maintenance.

Step 5: Build structured external signals Press mentions, industry directories, partner backlinks – external signals strengthen credibility with AI systems.

Conclusion

AI Overviews and zero-click are not temporary phenomena. They are the new normal in search. The right response isn’t panic – it’s a strategy shift: away from “generate as many clicks as possible”, towards “appear as a trusted source in AI answers”.

And the good news: the structural measures required for this simultaneously improve classical SEO. It’s an investment that works twice over.
