Here is the uncomfortable starting point for any conversation about search in 2026: a lot of the traffic you used to count on is never going to arrive. Similarweb put zero-click searches at roughly 69% of Google searches by the middle of 2025, up sharply year on year. When Google shows an AI Overview, the share of searches that end without a click climbs higher still. You can argue with the exact percentages, and you should, because they swing wildly by study and sector. What you cannot argue with is the direction.

So the question is no longer just "are we ranking?" It is "when an AI answers the question, are we in the answer?"

AEO and GEO, in plain English

Classic SEO is about ranking a page so a person clicks a blue link. The newer disciplines shift the goal:

  • AEO (Answer Engine Optimisation) is getting your content pulled out as the direct answer, the snippet or the AI Overview.
  • GEO (Generative Engine Optimisation) is getting your brand cited or named when a model like ChatGPT, Gemini or Perplexity synthesises a reply.

In practice people use the two terms interchangeably. The shared idea is simple: you are optimising to be the answer, or the source quoted inside it, not just the result underneath it. That changes the scoreboard too. Rankings and clicks give way to citations, brand mentions and your share of AI voice.

The part nobody wants to hear: ranking first is not enough anymore

It used to be that if you owned the top organic positions, you owned the snippet by extension. That link is weakening. Ahrefs and others have tracked the share of AI Overview citations coming from the top ten organic results falling steadily, with more citations now drawn from pages ranking far deeper, and from places like YouTube and Reddit. The studies disagree on the exact numbers, but the pattern is consistent: being number one is helpful and no longer sufficient.

Stop fighting for the click you have already lost. Win the citation instead.

What actually earns a citation

The single most useful piece of evidence here is the Princeton-led GEO study (SIGKDD, 2024), which tested optimisations across thousands of queries. The things that measurably raised the odds of being cited were not tricks. They were:

  • Citing statistics and naming concrete numbers in your content.
  • Quoting sources and experts rather than asserting things flatly.
  • Answering the question directly, high up, in a tight 40 to 60 word passage a model can lift cleanly.

Beyond that study, the correlational evidence points the same way. Earn mentions on the third-party sources models lean on, your industry press, well-regarded listicles, Reddit threads, YouTube. Keep your entity signals consistent so a model knows who you are: the same business name everywhere, a tidy knowledge-graph presence, structured data on your key pages. Keep important content in clean HTML with real headings, lists and tables, because that is what extracts well. And update things, because some engines, Perplexity especially, clearly reward freshness.

One honest caveat. llms.txt, the proposed file for telling models how to read your site, is low effort but currently low payoff. No major provider has committed to using it, and Google has said it will not. File it under "cheap to add, do not expect citations from it."

The upside hiding in the scary numbers

Here is the part that reframes the whole thing. The visitor who does arrive from an AI surface tends to convert far better than a typical organic visitor, because the model has already done the filtering. Estimates vary and one widely shared figure is an outlier, but a defensible cross-industry read is something like four to five times the conversion rate. A smaller, AI-shaped audience can be worth more than the traffic graph you are mourning.

How we audit for it

Our AI Visibility Audit tests how your brand actually shows up across ChatGPT, Gemini, Perplexity and Google's AI surfaces, where competitors are being cited instead of you, and which entity, content and citation gaps to close first. If your traffic is softening and you suspect the answer is being given without you, that is exactly the gap it is built to find.
