AEO vs SEO vs GEO
Three disciplines. One goal: get found. Here’s how they differ — and why smart marketers need all three.

The biggest difference at a glance
SEO goal
Get a user to click your link from a list of search results. You need to rank and earn the click.
GEO goal
Get your brand mentioned when AI generates articles, emails, or summaries — even without a link.
AEO goal
Become the cited source when an AI directly answers a user’s question in real time.
Why you need all three — not just one
Search behavior is fragmenting. Some users still type keywords into Google (SEO). Others ask AI chatbots to write content or summarize topics for them (GEO). And a growing number skip traditional search entirely and just ask Perplexity or Google AI Overviews for a direct answer (AEO). Ignoring any one of these means going invisible to a real slice of your audience. The good news: strong content that is clear, credible, well-structured, and authoritative tends to win across all three — they share the same foundation.
