AEO vs SEO vs GEO: What's the Difference, and Which Do You Need?

SEO optimises your pages to rank among the links in search results. AEO (Answer Engine Optimization) optimises your content to be cited inside AI-generated answers. GEO (Generative Engine Optimization) is another term for that same AI-answer goal. They are not competing choices — most businesses now need all three working together, because customers move between Google links and AI answers within a single buying decision.

SEO: optimising to rank

Search Engine Optimization is the long-established practice of getting your pages to rank highly in search engines like Google and Bing. It rewards relevant keywords, quality content, technical health, page speed, and backlinks. The payoff is a position in the list of results, and the click that follows. SEO still matters: it drives traffic, and a strong, well-structured site is also the foundation AI engines draw from.

AEO: optimising to be the answer

Answer Engine Optimization focuses on getting your brand named inside AI answers — in ChatGPT, Perplexity, Google AI Overviews, Gemini and Microsoft Copilot. The signals overlap with SEO but tilt toward clarity and credibility: answer-first content, question-led structure, specific extractable facts, strong entity recognition, and corroboration across trusted sources. Learn the full playbook in how to get cited by AI search.

GEO: the same goal, a different label

Generative Engine Optimization is, in practice, a synonym for AEO. Both describe optimising for generative AI systems that produce answers rather than lists of links. Some practitioners use "GEO" for the broader strategy and "AEO" for the question-and-answer tactics within it, but the distinction is mostly semantic.

Side-by-side comparison

Are they really different?

The overlap is real — clear, authoritative, well-structured content helps in both worlds, and good SEO is part of the AEO foundation. But the gap is real too: an Ahrefs study in early 2026 found only about 38% of pages cited in Google's AI Overviews also rank in the traditional top 10. Optimising only for rankings leaves AI visibility on the table.

Which does your business need?

Almost certainly all three, but the emphasis depends on where your buyers are. If your customers still research mostly via Google, SEO carries more weight. If they increasingly ask AI assistants for shortlists and recommendations — which is the direction of travel — AEO/GEO becomes essential. The efficient approach is one content system that serves both: pages that rank and are structured to be cited.

FAQ

Should I stop doing SEO and switch to AEO?

No. SEO still drives traffic and underpins AEO. The right move is to add AEO practices to your existing SEO, not replace it.

Is GEO different from AEO?

In practice they describe the same goal — optimising to appear in generative AI answers. Treat any claim that they're entirely separate services with healthy scepticism.

Does FAQ schema still help?

It no longer produces FAQ rich results in Google (retired May 2026), but Google still parses it and AI crawlers read it. Clear Q&A content remains one of the easiest formats for AI to cite.
