• SEO ranks your page in a list of results.
• AEO wins the single direct answer extracted from a page.
• GEO gets your brand named and cited inside an AI-generated answer.

They share one foundation — a crawlable, well-structured, trustworthy website — but each surface rewards different details. Treating them as one strategy, instead of three projects, is the practical way to work in 2026.

How AI engines actually pick sources

Most generative search systems follow a retrieval pipeline: they search an index, retrieve a small set of pages, then generate an answer from what they retrieved. Two consequences follow for SEOs:

1. If you are not retrieved, you cannot be cited. Indexation, crawl access (including AI search crawlers in robots.txt) and content available in raw HTML are gates, not nice-to-haves.
2. If your answer is not extractable, you will not be quoted. Long introductions and marketing language lose to a direct one-or-two-sentence answer placed at the start of a section, under a question-shaped heading.

A working checklist

• Test your top 15–25 buyer questions in ChatGPT, Perplexity, Gemini and Google AI Overviews. Log who gets cited — you or a competitor.
• Make entity details (name, location, services) identical on your site, LinkedIn, Google Business Profile and directories.
• Restructure priority pages answer-first, with question H2s, short paragraphs, lists and comparison tables.
• Add Organization / LocalBusiness, Article and FAQPage schema that matches the visible text.
• Add verifiable statistics, named sources and expert quotations to key pages.
• Build one comprehensive topic-cluster page that answers a full buyer question set, not ten thin posts.
• Re-test quarterly. AI answers drift as indexes and models update.

The takeaway

Good SEO is still the entry ticket: Google has been clear that normal search best practices are what AI features build on. AEO and GEO are the extra discipline of making that same content quotable — clear enough, early enough and corroborated enough for a machine to repeat it with your name attached.
