SEO vs GEO vs AEO: what's the difference, and which does a local business need?

SEO helps your pages rank in search results. AEO (answer engine optimization) helps your content become the direct answer: featured snippets, voice answers, AI summaries. GEO (generative engine optimization) helps AI assistants like ChatGPT name your business. A local business needs all three, built on the same foundation.

The short version

  • SEO (search engine optimization): be found and ranked in Google's and Bing's results.
  • AEO (answer engine optimization): be the answer a search engine or voice assistant reads out, like a featured snippet.
  • GEO (generative engine optimization): be named or cited when an AI assistant writes an answer.

Why they overlap so much

All three reward the same thing: a clear, trustworthy answer to a real question. Assistants with web search start from search results, and Google says its AI features use the same fundamentals as regular Search. So SEO is the foundation; AEO and GEO are about how your content is written and where your business is described.

Where they differ

  • What you measure: SEO measures positions and clicks; AEO measures whether you hold the snippet or the spoken answer; GEO measures how often assistants name you and cite your site.
  • What wins: SEO rewards relevance and authority across a whole page; AEO rewards a concise, direct answer near the top; GEO rewards facts an assistant can verify and presence on the third-party sources it reads.
  • Where the competition is: on Google you compete for ten blue links; in an AI answer you compete for two or three names.

What a local business should do first

  1. Fix the SEO foundation: pages indexed, a complete Google Business Profile, consistent name, address and phone everywhere.
  2. Rewrite key pages answer-first: the direct answer in the first two sentences, then the details. That serves AEO and GEO at once.
  3. Add verifiable facts with dates and sources, and FAQ sections with structured data.
  4. Get listed and reviewed on the sites assistants cite for your trade and city.
  5. Measure all three: positions, snippets, and AI mentions, every week.

Questions

Questions people ask

Is GEO replacing SEO?

No. Assistants with web search start from search results, so SEO stays the foundation. GEO adds a layer focused on being named in AI answers.

What does AEO stand for?

Answer engine optimization: shaping content so search engines and voice assistants use it as the direct answer, for example in a featured snippet.

Is AEO the same as GEO?

They're close. AEO usually means direct answers in search engines and voice assistants; GEO means being named or cited by generative AI assistants such as ChatGPT, Claude and Perplexity.

Which one should a small business start with?

SEO basics first (indexed pages, a complete Google Business Profile, consistent details), then answer-first pages, which help AEO and GEO together.

Can one page do all three?

Yes. A page with a direct answer up top, clear facts with sources, FAQ markup and good SEO fundamentals serves all three.
