Ask ten business owners what SEO is and most will get close: it's how you rank on Google. Ask them what AEO or GEO is and you'll mostly get blank looks — which is a problem, because a growing share of their customers no longer start at Google at all. They ask ChatGPT. They ask Perplexity. They read the AI answer at the top of the search page and never scroll to the links.

Getting found in 2026 means being present in all of those places. Here's what each of the three disciplines actually does, in plain English.

SEO — ranking on search engines

Search Engine Optimization is the classic discipline: structuring your site so Google, Bing, and Maps rank it for the searches your clients already make. For a high-trust business the work is concrete — clean page structure and headings, schema markup that tells engines exactly who you are, service pages that match real searches, local signals like a complete Google Business Profile, and reviews.

SEO still matters enormously. Google still handles billions of searches a day, and for local "near me" intent it remains the front door. But it is no longer the whole game.

AEO — getting cited by answer engines

Answer Engine Optimization is about the tools that answer instead of listing: ChatGPT, Perplexity, and voice assistants. When someone asks "who's a good pediatric endocrinologist near Hollywood, Florida?", the assistant doesn't return ten blue links — it names two or three practices.

AEO is the work of becoming one of the names. That means question-led content that directly answers what clients ask, entity data (schema) that lets an AI confidently say who you are, where you are, and what you do, and authority signals — citations, reviews, consistent business data across the web — that make the model trust you enough to recommend you.

The difference from SEO is subtle but important: SEO earns a ranking; AEO earns the citation inside the answer itself.

GEO — surfacing in generative results

Generative Engine Optimization covers the AI layer inside search engines themselves — Google's AI Overviews and the generated summaries that now sit above the classic results. These summaries are assembled from sources the engine considers clear and trustworthy, and they get read instead of the links below them.

GEO leans on the same raw materials as AEO — clean entities, direct answers, authority — tuned for how generative engines pick sources. If an AI Overview answers your customer's question without naming you, a #3 ranking under it is worth far less than it used to be.

One foundation feeds all three

Here's the part most agencies miss: these aren't three separate projects. A site built properly — real schema graph, question-led content, fast pages, consistent business data, genuine reviews — feeds all three channels at once. The same foundation that ranks you is what gets you cited.

That's also why bolting "AI optimization" onto a weak site doesn't work. If the structure underneath is thin, there's nothing for the answer engine to trust.

What to do about it

  • Search your business name in an incognito window. Does a knowledge panel appear? Is the information right?
  • Ask ChatGPT and Perplexity what your business does and who it serves. If they don't know or get it wrong, your entity data is thin.
  • Check that your site answers the questions clients actually ask — in text an engine can quote, not just images.
  • Make sure your Google Business Profile, site schema, and directory listings all agree on your name, address, and phone.
