The GEO guide

What is GEO, and why it decides who AI recommends.

Q: How is GEO different from SEO?

SEO optimizes for blue links and keyword rankings on search engines. GEO optimizes for being named inside the AI's answer. A page can rank low on Google and still be the source ChatGPT cites, so the two are measured and worked on separately.

Q: How do AI models decide which brands to recommend?

AI models draw on the sources they trust: community threads like Reddit, review sites, editorial coverage and well-structured pages. Being mentioned in those places often matters more than backlinks.

Generative Engine Optimization (GEO) is how brands get recommended inside AI answers from ChatGPT, Gemini and Perplexity. Here is what it is, how it differs from SEO, and how to improve it.

Definition

GEO in one sentence

GEO is the practice of getting your brand named inside AI answers, the way SEO gets you ranked on Google. Instead of optimizing for blue links, you optimize for the sources an AI model cites when a buyer asks it what to use or buy.

When someone asks ChatGPT "what is the best tool for X", the model does not read your whole website. It assembles an answer from the sources it already trusts, and names a short list of brands. GEO is the work of making sure your brand is one of them.

GEO vs SEO

Same goal, different game

Both put you in front of buyers. But they optimize for different surfaces, and a page can win one while losing the other.

SEO

Optimizes for search engine rankings and blue links.
Measured by keyword position and organic traffic.
The buyer clicks through and compares for themselves.

GEO

Optimizes for being named inside the AI's answer.
Measured by whether you are cited, your share of voice and sentiment.
The AI compares for the buyer, and hands them a short list.

A page can rank low on Google and still be the source ChatGPT cites, which is why GEO is measured and worked on separately from SEO.

Why it matters now

Buyers ask an AI before they Google

More and more buying decisions start with a question to an AI: what tool should I use, which store is best, who do people recommend. The AI answers with a handful of names. If yours is not on that list, you never enter the consideration set, and you never see the lost deal.

This surface is new and moving fast. The brands that work their AI visibility now take a position that late movers pay to catch up on.

How it works

How AI decides who to recommend

Models lean on the sources they trust. GEO is about being present, and clearly described, in those sources.

Community & reviews

Threads like Reddit, review sites and forums are cited heavily. Being mentioned there often matters more than a backlink.

Editorial & comparisons

Roundups, "best tool for X" articles and editorial coverage feed the short lists models hand back.

Clear, structured pages

Well-structured pages that state plainly what you do, for whom, and why, are easier for a model to quote correctly.

The playbook

How to improve your GEO

Measure where you stand

Run the questions your buyers actually ask across ChatGPT, Gemini, Perplexity and Google AI. Note where you are named, and where a competitor is named instead.

Trace the sources

For each answer, look at which pages and threads the model is building on. Those sources are your target list.

Close the gaps, on-page and off-page

On-page, publish clear content that answers those buyer questions. Off-page, get mentioned in the reviews, communities and roundups the models cite.

Track it over time

AI answers change constantly. Watch your share of voice move as you ship, and double down on what shifts citations.

Where Howseen fits. Howseen runs this loop for you: it tracks how ChatGPT, Gemini, Perplexity and Google AI talk about your brand, shows who gets cited instead of you, and turns each gap into content you can publish.
