AEO vs GEO vs SEO: What's the Difference?

SEO, AEO, and GEO are three overlapping disciplines for getting found online in the age of AI search. They are not competitors — they are layers. Here's what each one does.

The one-line difference

Term	Full name	What it optimizes for
SEO	Search Engine Optimization	Ranking your page in a list of results
AEO	Answer Engine Optimization	Getting your content quoted by AI assistants
GEO	Generative Engine Optimization	Getting your brand identified and cited by generative search

SEO: get the page ranked

Search Engine Optimization is the foundation. It covers crawlability, page speed, titles and meta descriptions, headings, internal links, and backlinks — everything that helps a search engine understand and rank your page. Without solid SEO, the other two layers have nothing to stand on, because an answer engine still has to crawl your page before it can quote it.

AEO: get the content quoted

Answer Engine Optimization is about making your content extractable. An AI assistant reading your page should be able to pull a clean, self-contained answer to a specific question. That means direct-answer paragraphs, question-shaped headings, lists and tables instead of dense prose, and FAQ content backed by FAQPage schema.

AEO is content-level and page-level. It answers the question: "When someone asks this, can the AI quote my page confidently?"

GEO: get the brand recognized

Generative Engine Optimization operates at the entity level. When an AI assistant answers "what are the best website audit tools?", GEO determines whether your brand is one of the names it recognizes and recommends. It depends on:

• Entity schema — Organization, Person, Product, or SoftwareApplication JSON-LD that clearly identifies who you are.
• E-E-A-T signals — author bylines, publication dates, and links to authoritative sources.
• Consistent mentions — your brand described the same way across your site and the wider web.

GEO answers a bigger question: "Does the AI know my brand exists, and does it trust it enough to name it?"

How they stack

Think of it as a pyramid:

1. SEO makes your page crawlable and rankable.
2. AEO makes the content on that page quotable.
3. GEO makes your brand the one the AI names.

Skip the bottom and the top has no support. Skip the top and you rank but never get recommended.

Measuring all three

Most tools only measure SEO. To see where you stand across all three layers, run a free audit — it returns a classic SEO score plus AEO and GEO readiness scores out of 100, each with specific fixes. You can also start with a focused SEO audit if that's your priority.
