AI search is changing how brands and publishers get found. The latest data shows fewer clicks from some Google results, more competition for AI citations and a growing gap between rankings, mentions and actual traffic.
- Google says AI Overviews now reach more than 2.5 billion monthly active users, while AI Mode has passed 1 billion monthly users.
- The early data suggests that traditional SEO still matters, but ranking, getting cited and earning clicks are no longer the same thing.
Generative Engine Optimization, or GEO, has quickly become one of the most debated topics in search.
Some marketers treat it as the next major shift after SEO. Others see it as a new label for work good SEOs were already doing: building trusted content, earning mentions, keeping brand data consistent and making pages easy to understand.
The truth is probably somewhere in the middle.
AI search does not replace SEO. But it changes what visibility means. Ranking on page one is no longer the only question. The bigger question is whether Google AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini or Copilot actually use your brand, your page or your data in the answer.

| Users clicked a traditional result in 8% of visits when an AI summary appeared, versus 15% without one | AI summaries appear to reduce traditional organic clicks in Google Search. | Pew Research Center |

What the numbers actually tell us
The data is not perfectly clean. Different studies use different keyword sets, countries, time periods and methods. Google also argues that AI in Search is driving more queries and higher-quality clicks, not simply reducing traffic to the web.
But the broad pattern is hard to ignore: search visibility is becoming less directly tied to clicks.
A page can rank well and still lose traffic if the answer is handled inside an AI Overview. A page can fail to rank in the top 10 and still appear as a cited source in an AI assistant. A brand can be mentioned in an AI answer without receiving a measurable visit in analytics.
That is the core GEO problem.
It is not just about ranking anymore. It is about whether an AI system can understand, trust and use your content.
The click problem is real, but not evenly distributed
The clearest click-loss data is still around informational queries.
Basic definitions, simple explainers, quick facts and generic “what is” content are the most exposed. If Google can answer the query directly, many users have less reason to click through.
That is why publishers, affiliates and SEO-heavy content sites feel the pressure first. Many of those businesses were built around informational traffic. If that traffic gets answered directly on the results page, the old model becomes weaker.
But this is not only a publisher issue anymore.
Semrush found that AI Overviews are moving further into commercial, transactional and navigational queries. That matters because these are the searches closer to revenue. If AI answers start shaping product comparisons, brand choices and purchase decisions, GEO becomes a business visibility issue, not just an SEO topic.
AI citations are not the same as rankings
The citation data is where the discussion gets more interesting.
BrightEdge and seoClarity both suggest that organic rankings still matter for Google AI Overviews. Pages that already rank well have a better chance of being included, especially inside Google’s own search ecosystem.
But the overlap is not complete.
BrightEdge found that 54.5% of AI Overview citations now come from pages that also rank organically. seoClarity found that AI Overview citations overlap with top 10 organic results around 32% of the time. Ahrefs found that for ChatGPT, Gemini and Copilot, only 12% of cited URLs also ranked in Google’s top 10 for the same prompt.
That means “rank number one” and “get cited by AI” are related, but not identical.
For Google AI Overviews, classic SEO is still a strong foundation. For ChatGPT, Perplexity, Gemini and Copilot, the picture is more fragmented.
What GEO probably means in practice
The market wants a simple GEO playbook. The data does not support one yet.
There is no strong proof that adding an llms.txt file, rewriting headings for AI or adding a few “AI-friendly” summaries will suddenly make a brand appear in answers.
The stronger pattern is more basic:
- Clear pages are easier to understand.
- Specific content is easier to cite.
- Strong topical coverage still helps.
- Trusted brands are safer for AI systems to mention.
- Consistent brand data reduces confusion.
- Third-party validation can support credibility.
- First-hand experience is harder for AI summaries to replace.
In other words, GEO is not magic. It is SEO, content strategy, brand building and data consistency pushed into a new search environment.
The Query Post view
GEO is real as a visibility problem, but still immature as a discipline.
The wrong move is treating it like a shortcut. The better move is to think about how AI systems choose sources, how they describe brands and how often they trust a site enough to cite it.
Traditional SEO is not dead. The data actually suggests the opposite. Rankings still matter, especially in Google AI Overviews.
But rankings are no longer the full story.
Search visibility is splitting into three layers:
- Classic organic rankings.
- AI citations and source inclusion.
- Brand mentions inside generated answers, even when no click happens.
That last layer is the hardest to measure. A user may see a brand inside an AI answer, remember it and never visit the website directly from that answer. That influence exists, but it may not show up clearly in Google Analytics.
For now, the safest GEO strategy is not to chase every new tactic. It is to make your site and brand easier to understand, easier to verify and easier to cite.
The click is no longer guaranteed. The ranking is no longer the whole game. And visibility may increasingly happen inside an answer that users never leave.
