Whats the difference between SEO and GEO?

I’ve been saying for a while that GEO isn’t some revolutionary new discipline that replaces SEO. The industry keeps trying to make it one. New acronyms, new gurus, new tools promising AI visibility like it’s a separate game you need to learn from scratch.

It’s not. But something significant did change. And the cleanest way to express it is this: GEO = SEO + QFO.


The SEO half hasn’t moved. LLMs like Perplexity, Gemini, and ChatGPT are synthesizers, not independent search engines. They sit on top of the same web infrastructure Google built, weighted by the same link signals PageRank has always cared about. Studies consistently show up to 87% overlap between AI citations and top organic results. That’s architecture, not coincidence. If you’ve been doing solid SEO, you’re already most of the way there.

The QFO half is where the new work lives.

When someone types a query into an AI system, that exact query is almost never what gets searched. The system fans it out — decomposes the question into a cluster of sub-queries, runs those separately, and stitches together an answer from whatever sources cover each one best.

Say someone asks “best GEO strategy for a SaaS company.” The AI silently spins off questions like: what is GEO, how do LLMs select sources, GEO vs SEO for B2B, implementation considerations, risks and limitations. Each one is a citation opportunity. A page that ranked sixth for the main query might get cited repeatedly because it’s the web’s best answer to one of those hidden sub-queries.


So stop thinking in keywords. Start thinking in conversation clusters. Map the Query Fan Out for any topic you want to own. Does your content cover those sub-questions, or does it stop at the surface?

GEO without SEO is a house with no foundation. SEO without QFO is leaving real visibility on the table.

The practitioners who win aren’t the ones who abandoned SEO for GEO. They’re the ones who understood that GEO is just SEO with the Query Fan Out mapped in.

GEO = SEO + QFO. Write it down.
