Short answer: AEO and GEO are SEO with a different goal, not a separate discipline. AI answer engines cite pages that are crawlable, indexed and eligible for a snippet, so ordinary SEO is the foundation. What earns the citation is a specific, answer-first page with checkable evidence: dated numbers, named sources and your own data. Google says there is no special AI schema and its Search does not use llms.txt. Start with SEO vs AEO vs GEO, then the checklist, then the guide for the engine your buyers use.

FAQ

Common questions

What is the difference between SEO, AEO and GEO?

SEO aims to rank pages and win clicks. AEO aims to have a passage from your page used as the direct answer in featured snippets, voice and AI Overviews. GEO aims to have ChatGPT, Perplexity and Google AI Mode mention and cite your brand accurately. All three depend on crawlable, indexed, useful pages.

How do I get into Google AI Overviews?

Make sure the page is indexed and eligible to show with a snippet, Google's only stated technical requirement, and that your site is not excluded in Search Console's generative AI setting. Then publish a specific, answer-first section for each sub-question buyers ask, backed by your own data. Inclusion is never guaranteed.

What structured data helps AI search engines cite my pages?

No markup directly causes an AI citation; Google says there is no special AI schema. Markup that removes ambiguity helps: Organization for identity, Article or BlogPosting with real authors and dates, LocalBusiness for real locations and Product for ecommerce, all matching the visible page.

How do I get my website cited in ChatGPT search?

Allow OAI-SearchBot in robots.txt and make sure your firewall does not block OpenAI's published IP addresses; OpenAI says sites opted out of OAI-SearchBot are not shown in ChatGPT search answers. Blocking GPTBot, the training crawler, is a separate setting. Then answer specific questions with dated facts.
