AEO & GEO: How to Get Cited by ChatGPT, Perplexity and Gemini in 2026

AI search engines — ChatGPT Search, Perplexity, Gemini, Claude — increasingly intercept the queries that used to flow to Google. They do not just rank pages; they synthesise answers and cite a handful of sources. If your brand is not in that citation list, you are invisible at the moment of intent.

Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) are the practices of structuring content so that it is the source a model picks. The mechanics overlap with SEO but the optimisations are different: clarity over keyword density, structured data over backlinks, direct answers over long preambles.

First, write the answer in the first paragraph. Models grab the lede, not the conclusion. A clear, one-sentence answer followed by supporting detail is the format that gets quoted.

Second, ship FAQ, Article, HowTo and Organization JSON-LD on every page. Schema is how a crawler turns a paragraph into a citable fact.

Third, publish an llms.txt file at the root of your domain. It tells AI crawlers which pages you want them to read, in what priority — analogous to robots.txt but for retrieval-augmented generation.

Fourth, use question-led H2s. "How long does an SEO audit take?" beats "Audit Timeline" by a wide margin in models trained to match queries.

Fifth, link to original data and primary sources. Citations beget citations — a model is more likely to quote a page that itself cites well.

Track AI citations the same way you track backlinks. Tools like Profound and Otterly monitor when your domain appears in ChatGPT and Perplexity answers, broken down by prompt.

Combine those signals with traditional Search Console data — AEO and SEO compound, they do not compete.
