What is GEO, and why does it matter for your site?

GEO — Generative Engine Optimization — is making your site easy for AI assistants to understand, trust and quote when someone asks them a question.

Search is now two places

People still search Google — and more and more of them also ask ChatGPT, Gemini or Perplexity. Those assistants answer in their own words and mention a handful of businesses or pages. GEO is about being one of them.

SEO

Rank in the list of links

Search engines crawl your pages and rank them. Titles, descriptions, headings, speed and broken links all play a part.

GEO

Get named in the answer

AI assistants read your pages and decide what to say about you. Clear facts about who you are, direct answers to common questions and well-structured pages make that easier.

Five engines, five scores

Each assistant favours different things, so Mantis scores every page for each one. Your overall GEO score combines the five, with ChatGPT and Gemini counting most.

ChatGPT

  • A clear H1 that names your main topic

You.com

What moves a GEO score

1

Say who you are

Your business name, what you do and where you work, stated plainly — and in structured data (Schema.org) too.

2

Answer real questions

FAQ sections with question headings and a short, direct answer first. These are easy for assistants to quote.

3

Get the basics right

Titles, descriptions, headings, canonical tags and working links. Good SEO is the foundation of good GEO.
