Ask a hundred bloggers where their readers come from and you'll hear the same story. Traffic that once arrived from a Google results page now sometimes comes from an answer box, a chatbot citation, or nowhere at all, because the reader got what they needed *without clicking. If you publish online in 2026, "how do I rank?" is only half the question. The other half is how AI search engines decide whose work to quote.*
What "AI Search" Actually Means Now
ChatGPT with search turned on, Perplexity, Google's AI Overviews and AI Mode, and Claude with web access all answer a question in natural language and usually attach links to the pages they drew from. Google's AI Overviews reportedly reach around two billion people a month, which is why they matter even to people who never open a chatbot.
The industry has started calling the effort to get cited by these tools generative engine optimization (GEO) or answer engine optimization (AEO). Both terms are new, and so is much of the evidence behind the advice circulating about them.
Why Each Platform Picks Different Sources
The differences come down to architecture. Perplexity was built around citations from day one, running a live web search for each question and tying claims to specific sources. ChatGPT blends what the model learned in training with a retrieval layer that fetches web results when a question needs them. Google AI Overviews and AI Mode draw on Google's own index, which means ordinary SEO fundamentals still shape what they cite.
A frequently cited analysis of roughly 680 million citations found that only 11% of domains are cited by both ChatGPT and Perplexity, and that around 71% of cited sources appear on just one platform. "AI search" is not a single channel. What works on one may do very little on another.
What Content Tends to Get Cited
A few patterns show up repeatedly across the data. Content that defines its terms at the start and states facts plainly is easier for a retrieval system to lift into an answer. Pages with original data, named sources, and visible author credentials appear to be favored over vague, opinion-heavy ones. Structure helps too: clear headings, short paragraphs, and comparison tables give a model something clean to extract.
One detail worth noting: a study from the Tow Center at Columbia Journalism Review reportedly found AI search tools gave incorrect answers on more than 60% of the news queries it tested. Being cited isn't the same as being represented accurately.
A Practical Starting Point
Open each article with a short, direct answer or definition, the way a reference page would. Name primary sources so a reader, or a model, can verify a claim. Include original numbers or first-hand testing where you can. And check the basics: confirm your pages are actually indexed in Google Search Console, since a page that can't be crawled can't be cited by anyone.
