SEO vs AEO vs GEO vs AIO: what is the difference?
Four names, one goal: customers should find you — in Google results, in direct answers and inside AI assistants like ChatGPT and Gemini. Here is what each term means and how they fit together.
In short
- SEO (search engine optimization): rank your pages in Google and Bing results.
- AEO (answer engine optimization): be the direct answer — featured snippets, “People also ask”, voice assistants.
- GEO (generative engine optimization): be named and cited inside AI-written answers from ChatGPT, Gemini, Perplexity and Google AI Overviews.
- AIO (AI optimization): make your website easy for AI systems to read, understand and trust — the technical base that GEO and AEO stand on.
SEO: be found in search results
SEO is the foundation. It covers fast pages, a clear title and description on every page, useful content for the searches your customers make, a sitemap, mobile-friendly design and links from other trusted websites. Without good SEO, AI tools have little reliable material about you to work with.
AEO: be the direct answer
AEO focuses on questions. When someone asks “How much does a root canal cost in Kannur?”, search engines and voice assistants try to show one short answer. Pages that put the answer in the first sentence, use question headings and add FAQ structured data are more likely to be picked.
GEO: be named by AI assistants
GEO is about generative AI. ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews write answers and often name specific businesses. They prefer businesses whose details are clear and consistent across the web: website, Google Business Profile, directories, reviews, social profiles and articles that mention them.
AIO: make your website readable for AI
AIO is the technical side: allowing AI crawlers in robots.txt, adding an llms.txt summary, business structured data (Organization or LocalBusiness), FAQ schema, a visible “last updated” date, correct language settings and fast server responses. Doondo checks all of these every day for its customers and gives ready-to-paste fixes.
How they work together
| Goal | Where it shows | Main work | |
|---|---|---|---|
| SEO | Rank pages | Google & Bing results, Maps | Content, speed, titles, links, local profile |
| AEO | Be the answer | Snippets, “People also ask”, voice | Answer-first writing, FAQ schema |
| GEO | Be recommended | ChatGPT, Gemini, Perplexity, AI Overviews | Consistent facts, mentions, reviews, citations |
| AIO | Be readable | Everything above | AI crawler access, llms.txt, structured data |
What to do first
- Fix the basics: titles, descriptions, speed, mobile, sitemap.
- Open your website to AI crawlers and add business structured data and an llms.txt file.
- Answer your customers’ real questions on your pages, in the languages they use — including Manglish, Hinglish and other English-letter typing.
- Keep your business details identical everywhere: website, Google Business Profile, Facebook, Instagram, directories.
- Check every week whether AI assistants name you, and improve what is missing.

Frequently asked questions
Which is most important: SEO, AEO, GEO or AIO?
SEO is the foundation, because AI tools rely on the same well-built, trustworthy pages. AIO, AEO and GEO build on top of it. Doing them together gives the best result.
Is GEO the same as AEO?
They overlap. AEO aims to be the single direct answer in search features and voice assistants. GEO aims to be named and cited inside longer AI-written answers from tools like ChatGPT and Gemini.
What does AIO mean in marketing?
AIO means AI optimization: preparing a website so AI systems can read and trust it — AI crawler access, an llms.txt summary, structured data, clear facts and fresh dates.
Can anyone guarantee a #1 position in Google or ChatGPT?
No. Nobody controls Google rankings or AI answers. Good work makes accurate, prominent mentions much more likely, and progress can be measured week by week.
Do these work for Malayalam and other Indian languages?
Yes. People search and ask AI in their own script, in English letters and in English. Pages and answers in those forms help you show up for all of them.
