The search results page changed. Google increasingly answers the question on the page, with an AI Overview, and most people never click through. AEO is the work of being inside that answer, cited and credited, rather than ranking beneath it.
This isn’t a fringe surface. AI Overviews reach billions monthly, and when one appears, clicks to traditional results collapse. If your buyer’s answer is being assembled in front of them, you want to be in it.
The good news: what wins AI citations is the brand authority good SEO already builds, so this is learnable, winnable work. Here’s the data, and how we win it.
AI Overviews now answer billions of searches.
AEO matters because the answer surface is no longer niche. Google’s AI Overviews reach more than 2.5 billion monthly users, up from 2 billion a year earlier, and Google says the feature is driving over 10% more queries where it appears.
That’s the new front page of search: an answer, assembled by Google, for billions of people. Being absent from it is being absent from search.
The answer surface, at scale
When the AI answers, almost nobody clicks through.
Here’s why ranking alone is no longer enough. When an AI Overview appears, users click a traditional result just 8% of the time, versus 15% without one, and only about 1% click a link inside the summary. Across all Google searches, 68% now end with no click to the open web at all.
If you’re not in the answer, you’re increasingly invisible, no matter where you rank beneath it. AEO is how you stay seen.
When an AI Overview appears, 1% of people click a source inside it. Being the answer beats ranking under it.
Share of searches that end without a click
AI answers cite brands, not keyword tricks.
What earns an AI citation is brand authority. Across 75,000 brands, the strongest predictors of AI Overview visibility were branded web mentions (0.664 correlation) and YouTube mentions (around 0.74), far ahead of raw backlinks (0.218). Raw site page count had essentially no correlation.
In other words, AEO is digital-PR and authority work, getting your brand mentioned, cited, and talked about across the web, not stuffing keywords. That’s exactly what we build.
What predicts an AI citation
AI answers still pull from pages that rank.
AEO compounds with SEO rather than replacing it. When Ahrefs analyzed 1.9 million AI Overview citations, 76% of cited URLs also ranked in Google’s top 10, with the median cited page at position two.
So the play is both: rank well to be eligible, then optimize specifically to be the cited answer. We run them together, because one feeds the other.
AI citations that also rank in the top 10
Citations are the new backlinks.
Put it together and the strategy is clear. The answer reaches billions, the click is collapsing, and being the cited source is what visibility now means. As Ahrefs’ CMO puts it, citations are the new backlinks for the AI search era.
AEO is how you earn those citations: authoritative, well-structured, genuinely-best answers, backed by a brand the web mentions and trusts. We build that, so when the AI answers, it answers with you.

If your brand is mentioned in a ton of different places on the web, that correlates very highly with AI visibility.
