SEO vs GEO vs AEO: What European Marketers Should Know

The shorthand can be confusing: SEO addresses organic search discovery and usability; GEO focuses on how content is represented or cited in generative experiences; AEO focuses on clear answers to user questions. They overlap, and a brand does not need three disconnected strategies for them.

AI search visibility, GEO and answer-engine optimisation

What traditional SEO still does

Accessible pages, meaningful headings, canonical consistency, fast loading, relevant internal links and trustworthy information remain foundational. Search engines and answer systems often encounter information through indexed content, retrieved documents and third-party sources. A weak website does not become strong because it adds a new acronym.

What GEO adds

Generative systems may synthesise answers rather than send a click directly to a website. This makes factual clarity, consistent entities, supported claims and references across relevant sources especially important. Test a defined group of customer questions and record citations with dates and context.

No general “LLM ranking” works exactly like one stable blue-link ranking. An AI answer can change across prompts and products.

What AEO adds

Question-driven writing can make a website useful to both people and answer systems. Answer the user’s direct question early; explain scope and exceptions; link to a detailed methodology for readers who need it. Do not create one low-value page per minor phrasing variation.

The role of schema

JSON-LD can describe a service, organisation, webpage, article and breadcrumb hierarchy consistently with visible content. It cannot guarantee rich results or AI citations. Google’s documentation on generative search continues to emphasise helpful, people-first content, relevant media and ordinary SEO basics.

What should you measure?

Use GSC clicks and impressions, qualified enquiries, relevant third-party mentions, specific query-set observations and content quality checks. Segment by country and buyer intent where data supports it. Keep uncertainty visible when discussing AI mentions.
