What is Generative Engine Optimization (GEO)?
Also known as Generative Engine Optimization (GEO).
Generative Engine Optimization (GEO) is the practice of making a website usable by AI answer engines like ChatGPT, Claude, Perplexity and Google's AI features, so they can crawl it, read it without JavaScript, and quote it as a source. It overlaps with SEO but optimizes for being cited rather than ranked.
- GEO and SEO diverge in three concrete places: most AI crawlers don't run JavaScript, retrieval reads your page as isolated fragments rather than as a document, and citation favors specific sourced claims over keyword coverage.
- The measurable factors come from published research. A 2024 study (Aggarwal et al., KDD) tested content edits across 10,000 queries and found adding statistics, quotable statements and cited sources produced the largest visibility gains.
- Most of the GEO industry sells citation monitoring, which tracks how often you are mentioned. That is an outcome metric. It cannot fix a robots.txt rule or a client-rendered page, which is where the actual technical wins are.
- No tool can guarantee a citation. Competition, query demand and model behavior are outside anyone's control. What you can control is whether anything technically prevents you being cited.

GigAI GEO Audit
One URL in, one AI-visibility report out: crawler access with Cloudflare detection, JS rendering, citability scored with published methodology, retrieval chunks, answer snippets and schema. Each finding linked to the free tool that fixes it.
Content Citability Scorer
Score any page or draft on the factors a published study (KDD 2024) measured as increasing AI citation: fact density, source citations, quotability, answer-first openings, question headings and self-containment. Every sub-score shows its formula and what it counted.
AI Crawler Access Checker
Check whether GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot, Bingbot and every other AI crawler can read your site. Real RFC 9309 robots.txt matching with the deciding rule quoted, plus Cloudflare default-blocking detection. Free, instant, no signup.
Retrieval Chunk Preview
See your page the way a RAG system does: split into retrieval chunks and read one at a time, with no surrounding context. Flags every fragment that collapses alone: pronoun openers, 'as mentioned above', sections that never name their subject.
Generative Engine Optimization (GEO) problems we solve
Hit one of these? Here's the fix.
- ChatGPT and other AI tools can't see my websiteWork through the three causes in order. Access first, rendering second, content last, because fixing content on a page crawlers can't reach changes nothing.
- AI tools can read my page but never quote itBeing readable isn't the same as being quotable. These checks measure whether there's anything on the page a model could safely repeat.
Frequently asked questions
Related terms
- AI crawlerAn AI crawler is an automated bot that fetches web pages on behalf of an AI company, either to train a model, to build a search index that AI answers cite from, or to read a page live when a user asks about it. Each purpose is a separate bot with its own name in robots.txt.
- Retrieval-Augmented Generation (RAG)Retrieval-Augmented Generation (RAG) is how an AI answers using sources it was never trained on: it splits documents into chunks, finds the chunks that match the question, and hands only those fragments to the model. It is why your page is read as pieces rather than as a whole.
- llms.txtllms.txt is a proposed convention for a Markdown file at your domain root that gives AI systems a curated map of your site: a name, a one-line summary and grouped links. It is optional, and Google has stated its AI search does not use it.
- GPTBotGPTBot is OpenAI's web crawler that collects pages as training data for future models. It is not the bot behind ChatGPT Search results, and blocking it does not remove you from ChatGPT's answers. That is a different bot called OAI-SearchBot.
