SEO vs AEO vs GEO Search is no longer just about Google rankings. In 2025, buyers are finding vendors through three different discovery layers: SEO (Search Engine Optimisation), AEO (Answer Engine Optimisation), and GEO (Generative Engine Optimisation). Each plays a unique role in visibility, and ignoring any one of them creates gaps that cost you leads. This blog breaks down the differences between SEO, AEO, and GEO and why mastering all three is essential.
1. SEO: The Foundation of Discovery
SEO is the classic approach optimising your website for keywords, backlinks, schema markup, and technical performance. It ensures your business shows up in Google rankings when buyers actively search. But SEO alone can’t guarantee visibility in snippets or AI-driven answers.
Key Insight: SEO is the foundation of discoverability, but no longer the full picture.
2. AEO: Winning Zero-Click Answers
AEO focuses on structuring your content for featured snippets, FAQs, knowledge panels, and voice-first queries. With half of all searches ending without a click, AEO ensures your brand is part of the answers buyers see instantly.
Key Insight: AEO makes your brand visible even when buyers never visit your site.
3. GEO: The New Frontier of AI Discovery
Generative Engine Optimisation (GEO) ensures your content is included when AI engines like ChatGPT, Gemini, and Perplexity create “first draft” answers for buyers. Without GEO, you risk being excluded from the shortlist before the buyer journey even starts.
Key Insight: GEO secures your place in the AI-driven buyer journey.
4. Why They Work Best Together
SEO, AEO, and GEO aren’t competing they’re complementary. SEO brings traditional rankings, AEO wins zero-click visibility, and GEO makes you discoverable in AI engines. Together, they cover every discovery touchpoint in the modern buyer journey.
Key Insight: A layered strategy ensures you’re seen wherever buyers search.
5. The Cost of Ignoring One Layer
Relying only on SEO leaves you invisible in snippets and AI. Focusing just on AEO without GEO means AI engines ignore you. Skipping SEO entirely undermines credibility. The real danger isn’t choosing one it’s not connecting all three.
Key Insight: Visibility gaps in any layer equal missed opportunities.
