AI SEO — how to optimize for ChatGPT, Perplexity and Google AI Overviews
Published 2026-09-24 · Updated 2026-09-24
AI SEO, also called Generative Engine Optimization (GEO), is the work of getting AI tools to use and mention your site when they answer questions. The goal isn't a top-10 ranking — it's being one of the few sources the answer is actually built on.
What is AI SEO?
AI SEO is optimization for queries where an AI writes the answer. The term is sometimes also used for using AI tools to do SEO work, but in this guide it means showing up inside the AI-generated answers themselves.
What's the difference between SEO and AI SEO (GEO)?
Classic SEO optimizes a page for a search phrase and is measured by ranking and clicks. AI SEO optimizes for being cited and is measured by how often you're mentioned or used as a source. The foundations — good content, technical health and links — are the same, but AI rewards clarity and hard facts more than long-form copy.
- ▸SEO: keyword → ranking → click
- ▸AI SEO: question → citation → trust and click
How do you write content AI actually cites?
Start every section with the question as the heading and give the answer in the first sentence. Use concrete numbers, prices and comparisons. Avoid vague marketing copy — AI looks for self-contained passages it can lift out and quote on their own.
- ▸One question per heading, answer in 1–2 sentences right below
- ▸Lists and tables for comparisons
- ▸Visible last-updated date and author
- ▸Original data nobody else has

What technical work is required?
Make sure AI crawlers such as GPTBot, PerplexityBot, OAI-SearchBot and Google-Extended are allowed to read your site. Add structured data for your organization, products and FAQs. Keep pages fast and render content server-side so it's visible even without JavaScript.
Why do external mentions matter so much?
AI models trust what many independent sources say. Mentions on industry media, comparison sites, Reddit, forums and reviews make a model more likely to pick you — even when there's no link at all.
How do you measure AI SEO results?
Ask the questions your customers actually ask to several AI engines and count how often you're mentioned and cited. Repeat the measurement after every change. Our AI Visibility Score does exactly this automatically.

Frequently asked questions
Are GEO and AI SEO the same thing?
Yes, in practice. GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) are commonly used as synonyms for AI SEO.
Do I need to stop doing regular SEO?
No. Google's AI Overviews and Gemini are built on Google's index, so solid SEO is still a prerequisite for AI visibility.
How fast can I see results?
Tools with live search, like Perplexity and ChatGPT search, can react within a few weeks. Changes baked into the underlying language models take longer.
