What is the difference between SEO, AEO, and GEO?

2027 guide

A few years ago, only one word mattered in digital marketing — SEO.

Today there are three: SEO, AEO, and GEO. If you are confused about what each one means and why all three matter — this guide explains it in the simplest way possible.

What is SEO?

SEO stands for Search Engine Optimisation.

When someone types "best running shoes in Trichy" on Google and clicks a result — that website ranked there because of SEO. SEO helps your website appear in the list of blue links on Google.

It works through keywords, content, backlinks, and technical website health.

SEO goal: Rank higher in Google search results and get more clicks to your website.

What is AEO?

AEO stands for Answer Engine Optimisation.

Have you noticed that when you search something on Google, sometimes the answer appears directly at the top — before any website links? That box is called a Featured Snippet. The "People Also Ask" section is also AEO.

AEO is about structuring your content so Google pulls your answer directly and shows it to the user — even without them clicking your website.

Voice assistants like Siri and Google Assistant also use AEO. When you ask your phone a question out loud and it reads an answer back to you — that answer came from an AEO-optimised page.

AEO goal: Be the direct answer Google shows at the top — in snippets, PAA boxes, and voice search.

What is GEO?

GEO stands for Generative Engine Optimisation.

Today millions of people are getting their answers not from Google — but from AI tools like ChatGPT, Gemini, and Perplexity. When someone asks ChatGPT "which is the best SEO course in Trichy?" — ChatGPT reads multiple websites and generates one answer. GEO is about making your content trustworthy and structured enough that AI tools mention and cite your website in those answers.

GEO goal: Get your website cited and referenced inside AI-generated answers on ChatGPT, Perplexity, and Google AI Overviews.
