AEO vs GEO vs SEO: The Honest Difference

Here is the honest answer most agencies will not give you, because it costs them two invoices. SEO, AEO, and GEO are not three products. They are one job with a foundation. You need all of it, run together, from one team. What you do not need is three separate retainers with three separate reports for what is fundamentally one motion.

Now the real difference, because the terms do mean distinct things.

SEO is the foundation, not the enemy

The SEO is dead headlines are wrong, and it matters that you know why. Google AI Overviews source heavily from Google's own organic results. ChatGPT Search runs on Bing's index. If you are not in the index, you are not in the retrieval pool the AI draws from. SEO is how you get into that pool. Killing your SEO to go all in on AI is like removing the foundation to build a taller house.

AEO is being the answer, not ranking for it

AEO is the work of becoming the citation. That rewards different things than ranking: concrete, quotable, self-contained passages, third-party sources that name you, schema and llms.txt so engines understand you, and freshness. The biggest shift is off-site. Most of what makes an AI cite you happens on pages you do not own, so AEO that only touches your website is doing a fraction of the work.

AEO vs GEO: are they the same thing?

Mostly yes, and you should be suspicious of anyone who builds a wall between them to sell you both. GEO, generative engine optimization, names the same goal with emphasis on the generative engines specifically. AEO is the broader term and often includes featured snippets and voice answers too. In practice they are one workstream. Our stance at Ante is simple: AEO and GEO are the same job, we run them as one, and we run SEO underneath as the foundation. If a proposal lists SEO, AEO, and GEO as three line items with three prices, that is a pricing strategy, not a methodology.

So which one do you actually need?

• If you are not in the search index at all, start with SEO. Everything else feeds off it.
• If you rank fine but never get named when buyers ask ChatGPT or Perplexity, you have an AEO and GEO problem, and it is almost certainly off-site.
• If you are a funded B2B SaaS or a DTC brand watching AI answers eat your category, you need all three run together, foundation plus answer work, measured across every engine.
