WHAT IT IS
A GEO checker tests how ready a website is for generative engine optimization, meaning whether AI answer engines such as ChatGPT, Claude, Perplexity and Google AI features can access, read and cite your content. People increasingly ask these tools for answers instead of scrolling through search results, and a page can only be used if the tool is allowed to fetch it, can read it and can tell who published it.
Many sites fail the first step by accident, through a robots.txt rule or a firewall setting that blocks the crawlers behind AI search. This checker looks at those basics and points out what to fix. It measures readiness signals from outside your site. It does not ask AI tools questions, and it cannot promise a citation.
WHAT IT CHECKS
| Area | What it tests | Why it matters |
|---|---|---|
| AI crawler access | robots.txt rules for OpenAI, Anthropic, Perplexity, Google and Bing bots, a firewall test with bot user agents, and your sitemap | If a bot cannot fetch your page, it cannot use it. |
| Extractability | HTTPS and status, main content present in the raw HTML, indexability and server response time | Many AI crawlers do not run JavaScript, so content built only by scripts may be invisible to them. |
| Structured data and entity | Valid JSON-LD, an Organization or Person entity, sameAs profile links, page-type schema and Article fields | It helps machines tell who you are and what the page is. |
| Content citability | Title and description, one H1, an answer-first opening, question headings, lists, numbers and outside sources | Clear, well-structured pages are easier to summarize and quote. These checks are heuristics. |
| Trust and freshness | Author or publisher attribution, About, Contact and Privacy links, and last-updated dates | Clear ownership and recent dates support trust. |
AI CRAWLERS
The checker tests robots.txt rules bot by bot, because blocking a training crawler is very different from blocking an AI search bot.
| Type | Bots checked | What blocking it means |
|---|---|---|
| AI search bots | OAI-SearchBot, Claude-SearchBot, PerplexityBot | Your pages can drop out of that assistant search results. |
| User request bots | ChatGPT-User, Claude-User, Perplexity-User | The assistant cannot open your page when a person asks about it. |
| Classic search bots | Googlebot, bingbot | Google and Bing cannot crawl the page, which also affects AI features built on them. |
| Training bots | GPTBot, ClaudeBot, Google-Extended, Applebot-Extended, CCBot, Bytespider, meta-externalagent | A policy choice about model training. It is shown but not scored. |
Bot names and behavior change often, so check important findings against each vendor documentation.
HOW TO USE IT
SCORE
The score is built from the five areas above. Each check earns full, half or no points, and the total is scaled to 100. Access checks carry the most weight, because a blocked page cannot be cited at all. The bands are Strong at 85 or more, Decent at 65 or more, Weak at 40 or more and Poor below that.
The weights are my own judgment and the content checks are rules of thumb, not confirmed ranking factors. The llms.txt file is reported for information only, because no major AI provider has confirmed using it to choose citations.
CHECKLIST
COMPARISON
| GEO checker (this tool) | AI visibility tracker | |
|---|---|---|
| What it measures | Technical and content readiness signals on your site | Whether AI tools mention your brand in answers |
| How it works | Fetches your public pages and robots.txt | Asks AI tools a set of questions and records the answers |
| Best for | Finding fixable problems before you publish or promote | Tracking brand mentions over time |
The two answer different questions. Fixing readiness comes first, and tracking mentions comes after.

FAQ
A GEO checker tests how ready a website is for generative engine optimization, meaning whether AI answer engines such as ChatGPT, Claude, Perplexity and Google AI features can access, read and cite your content.
GEO stands for Generative Engine Optimization. It is the practice of making your site easy for AI answer engines to access, read and cite.
No. The score measures readiness signals that can be checked from outside, such as crawler access, readable HTML, structured data and clear content. Citation decisions are made inside each AI system and nobody outside those companies can guarantee them.
That is your call. Training bots such as GPTBot and ClaudeBot are separate from the bots that fetch pages for AI search and user questions. Blocking training bots is a policy choice and this tool does not score it as a problem. Blocking the search and user bots can remove you from AI answers.
Probably not for visibility. Public log studies suggest AI bots rarely request it, and none of the major AI providers has publicly confirmed using it to choose citations. This tool reports whether you have one for information only and gives it no points.
We send requests that carry bot names in the user agent, but real AI bots come from published IP ranges that firewalls often treat differently. A refusal is a sign to review your firewall settings, not proof that real bots are blocked.
The score is built from five areas: AI crawler access, extractability, structured data and entity signals, content citability and trust and freshness. Each check earns full, half or no points, and the total is scaled to 100. The weights are my own judgment, and the content checks are heuristics.
A GEO checker tests the technical and content signals on your site. An AI visibility tracker asks AI tools questions and records whether your brand is mentioned. This tool does the first only and does not query AI engines.
Yes. Whole site mode reads the pages in your sitemap, up to 1,500 pages, and combines the results into one score with a list of the weakest pages.
