AI Crawlability Checker

Can AI crawlers reach your page?

Checks robots directives, blocking headers, schema, page structure, FAQ formatting, alt text, and page size. Each issue spells out what's wrong and how to fix it.

What it checks
The stuff that determines whether AI systems can actually use your page.

Whether robots.txt blocks AI bots.

Meta tags and headers that block crawling (noai, X-Robots-Tag).

JSON-LD, FAQ markup, heading hierarchy.

Content density, alt text coverage, page weight.

How to fix crawlability issues

1
Remove crawl blocks

Check robots.txt, meta robots, and X-Robots-Tag headers. If any directive blocks AI bots (GPTBot, ClaudeBot, anthropic-ai), remove it or add explicit allow rules.

2
Add structured data

Add JSON-LD schema markup — Organization, FAQPage, Article, or Product depending on your page type. Schema helps AI models extract facts about your content.

3
Improve content structure

Use a clear heading hierarchy (single H1, logical H2–H3 nesting), add alt text to images, and keep pages under 200 KB. Dense, well-structured content is easier for AI to parse.

Background

Why AI crawlability matters

AI assistants don't rank pages — they decide whether to cite them. If crawlers can't access your page, AI models will never see it, and you'll never appear in AI-generated answers.

Unlike traditional SEO crawlers, AI crawlers (GPTBot, ClaudeBot, Google-Extended) often respect different robots.txt rules. Blocking one doesn't block all. Each model maker has its own crawler, and you need to manage access for each.

Crawlability is step zero for AI visibility. Fix technical access first, then optimize content structure and schema. Think of it as the prerequisite to generative engine optimization — if AI can't read your page, the rest is moot.

What AI crawlers check

AI crawlers look at these signals before ingesting a page. Any single failure can block you.

One-time check. Ongoing visibility.
This tool checks one page, once. Prompt Metrics tracks what AI assistants actually say about your brand — ChatGPT, Claude, Gemini, Perplexity, all of them — so you know when something changes.

Monitor how AI assistants describe your brand over time.

FAQ

AI crawlability checker FAQ

No. This checks whether AI crawlers can technically reach and parse your page. A clean report removes blockers, but it doesn't mean ChatGPT will cite you — that depends on content relevance, authority, and a dozen other things.

A missing robots.txt produces a warning, not an automatic failure. Most crawlers assume access is allowed when no file exists, but publishing explicit rules gives you more control.

Crawl blocks first — if bots can't reach the page, nothing downstream matters. Then fix schema and metadata. Content structure and alt text are last.

The checker inspects robots.txt rules, meta robots tags, X-Robots-Tag headers, JSON-LD schema, heading hierarchy, FAQ markup, image alt text, and page size. Each check returns pass, warn, or fail with the specific issue.

The tool checks robots.txt for rules targeting GPTBot (OpenAI), ClaudeBot and anthropic-ai (Anthropic), Google-Extended (Google AI), and general crawl directives. It also checks meta robots tags and X-Robots-Tag headers that apply to all bots.

Traditional SEO crawlability focuses on Googlebot accessing your pages for search indexing. AI crawlability covers a different set of bots — GPTBot, ClaudeBot, Google-Extended — that feed content into language models. You can be perfectly indexed by Google but completely invisible to AI assistants.

Yes. JSON-LD schema (FAQPage, Organization, Article, Product) gives AI models structured facts to pull from. It won't make you rank higher in AI answers, but it makes your content less likely to be misquoted or ignored.

After any robots.txt change, meta tag update, or CDN/firewall configuration change. Also check after major site redesigns or migrations. AI crawler user agents change over time, so periodic checks catch new blockers.
