What is GEO? Complete Guide to Generative Engine Optimization

What is GEO (Generative Engine Optimization)?

GEO, or Generative Engine Optimization, is an emerging discipline focused on a brand's presence and visibility in answers generated by large language models (LLMs) such as ChatGPT, Claude, Gemini, Grok or Perplexity.

Unlike traditional SEO, where the goal is to rank a web page in Google's results, GEO aims to have your brand mentioned, recommended and accurately described when a user asks an AI about products, services or companies in your industry.

Why Does GEO Matter?

Some users now open ChatGPT instead of a search engine when they want a shortlist: they describe their situation, ask which product or provider fits, and act on the names the answer gives. Whether that group is growing in your market is something you would have to measure with your own customers.

When a potential customer asks ChatGPT "what are the best email marketing tools?" or "which web design agency do you recommend?", the answer draws on what the model learned during training and, when the assistant searches the web, on the pages it finds.

If your brand doesn't appear in those answers, you may be missing opportunities without knowing it.

GEO vs SEO: What's the Difference?

GEO and SEO share the goal of increasing visibility, but they work differently:

• SEO targets index-based search engines (Google, Bing). The result is a link to your website that the user can visit.
• GEO targets generative engines that synthesize information and present it as a direct answer. The result is a mention within AI-generated text, sometimes with a link to a source.

SEO work aims at positions in a list of links; GEO work aims at being named, accurately, within the answer itself.

Another key difference is how visible the process is. In SEO, tools show your Google ranking. In GEO, answers vary with context, question wording and model updates, which makes monitoring harder and more necessary.

What Influences Which Brands AI Recommends?

The exact process isn't public, but several factors clearly play a role:

• Training data: public content up to the model's cutoff date. If your brand is well covered in articles, forums, reviews and directories, the model has more to draw on.
• Consistency across sources: brands described consistently by several credible sources give answers clearer material to work with.
• Context and sentiment: it's not just whether you're mentioned, but how. Reviews, articles and media coverage shape how your brand is described.
• Web search: Perplexity, and ChatGPT or Gemini when they search the web, draw on current pages, which makes your present online information important too.

Why Do Companies Need to Monitor Their AI Visibility?

Many companies don't know whether they appear in ChatGPT, Claude or Gemini answers, and what isn't measured is hard to improve.

Monitoring your AI visibility lets you:

• Know whether your brand appears when users ask about your industry.
• Understand your position relative to competitors in the answers.
• See the sentiment with which AI describes your company.
• Identify opportunities to improve your content and digital presence.
• Track changes after your content work, keeping in mind that other factors also change answers.

Without a tool, you'd have to run these questions manually, one by one, in each model, with different wordings — a slow process that's hard to repeat consistently.

How to Know if AI Mentions Your Brand

A tool like Mentio automates the process:

1. Define your brand and industry so the tool generates relevant questions.
2. Collects answers from the AI models included in your plan.
3. Analyzes the answers to detect whether your brand appears, in what position, with what sentiment and alongside which competitors.
4. Provides recommendations to improve your visibility (Pro and Enterprise plans).

The result is a report that shows how AI answers describe you and where to start improving.
