First-party audit: we ran 8 buyer prompts through ChatGPT, Perplexity, and Gemini. Two companies owned the category. The rest were invisible where it counts. The mid slots changed on every engine.
We use JYNLAB as the test case for our own AEO method, in public. Baseline: 0 of 4 AI engines cited us, and all four had a different wrong identity. The documented, step-by-step log of what we did, and the checklist you can steal.
Answer Engine Optimization (AEO) is how you get cited by ChatGPT, Perplexity, Gemini, and Claude when buyers ask for recommendations. What AEO is, how it differs from SEO and GEO, how engines decide what to cite, and how to get cited.
SEO ranks a link on Google. AEO gets you cited inside an AI answer from ChatGPT, Perplexity, and Gemini. Where they overlap, where they split, and how to decide where to put your effort.
A field-by-field teardown of how I rebuilt JYNLAB's LinkedIn so AI answer engines read it as one citable entity. Plus the live test: I asked four AI engines what JYNLAB does and got four different wrong answers.
AI engines do not cite at random. They retrieve candidates, weight them by authority and third-party consensus, then quote the clearest source. The selection mechanism, signal by signal, and how to win it.
There is no single best AEO agency. The right one measures your citation share across AI engines, builds third-party consensus, knows your vertical, and promises improvement, not guaranteed placement. The criteria, questions, and red flags.
Buyers ask AI for the best field service software for their trade. If your vertical SaaS is not named, you lose the deal before the demo. Why vertical SaaS is invisible in AI answers, and the narrow-context play to become the cited source.
You cannot pay ChatGPT to recommend you. You earn it. The practical, in-order playbook to get cited in ChatGPT, Perplexity, and Gemini: be retrievable, fix your entity, publish the direct answer, add schema, earn third-party mentions, measure.
