AI engines want clear, factual answers

Structure content as question then answer. Use H2/H3 headings that mirror how people ask questions. Answer in the first 1-2 sentences under each heading.

Schema markup is disproportionately important

AI engines lean on structured data to extract facts confidently. Article, FAQ, HowTo, and Product schema all raise citation odds noticeably.

Cite your sources - AI mirrors that

Pages that link to authoritative sources get cited more often than pages that make bare claims. Add credible outbound links to primary research.

Watch which engine sources what

ChatGPT Search uses Bing's index; Gemini uses Google's; Perplexity blends multiple. Ranking in Bing gets you into ChatGPT. Ranking in Google gets you into Gemini.

Track citations, not just rankings

Traditional rank trackers cannot tell you if ChatGPT cited you last week. An AI-visibility tool that runs your target prompts through each engine and logs citations is the only way to measure GEO.

FAQ

Does classic SEO still matter for AI search?

Yes - most AI engines pull from Google or Bing's index. If you are not indexed you cannot be cited.

Can I block AI crawlers and still rank in AI?

No. Blocking GPTBot, Google-Extended, and CCBot removes you from training and citation pools.
