SEO vs AEO vs GEO: what's actually different

Three acronyms, three different search surfaces — here's what each one is actually optimizing for.

If you've searched for how to grow your traffic recently, you've probably run into three near-identical acronyms: SEO, AEO, and GEO. They're related, but they're not the same thing, and treating them as interchangeable is how businesses end up optimizing for a search behavior almost nobody uses anymore while ignoring the one that's growing fastest.

SEO: getting found in a list of links

Search Engine Optimization is the original discipline — making a page rank well in Google's traditional list of blue links. It's built around keywords, backlinks, page speed, and matching what a searcher typed to what your page says. When someone searches "website developer near me" and clicks through a list of ten results, that's the SEO game.

AEO: getting picked as the answer

Answer Engine Optimization targets a different moment: when Google (or Bing, or a voice assistant) picks one single answer to show directly on the results page — a featured snippet, a "People Also Ask" box, a voice response. There's no list here; there's one winner. AEO leans on clear, direct answers to specific questions, FAQ schema markup, and content structured so a machine can lift one paragraph out cleanly.

GEO: getting cited inside an AI answer

Generative Engine Optimization is the newest of the three, and it's about showing up inside AI-generated answers — ChatGPT, Perplexity, Gemini, Claude, and similar tools that summarize an answer from multiple sources rather than linking to one page. These tools read differently than Google's crawler: they weigh clarity, structured data, and whether a page directly answers a question, over keyword density or backlink count.

Why you need all three, not one

These aren't competing strategies — they overlap in what makes a page good, but they optimize for different surfaces:

  • SEO gets you into the results list at all
  • AEO gets you the featured position within that list
  • GEO gets you cited when someone never even sees a list of links

A well-built page with solid structure, schema markup, and direct answers to real questions tends to perform well across all three, because the underlying discipline — being clear, well-organized, and genuinely useful — is what every one of these systems is actually trying to reward.

What to check on your own site

  • Does each page have one clear H1 and a logical heading structure?
  • Do you have FAQ or Q&A sections with schema markup, so engines can lift a direct answer?
  • Is your structured data (Organization, WebPage, FAQPage) present and valid?
  • Are your answers direct and near the top of the page, not buried under three paragraphs of preamble?
