Common Crawl Rank Checker: AI Visibility & Web Graph
Common Crawl is a nonprofit that crawls the open web every month and publishes the data for free. It is one of the largest open sources of training data used by AI models. This free checker looks up any domain's position in Common Crawl's web graph, shows how many pages were captured in recent monthly crawls, and checks whether CCBot and other AI crawlers can currently access the site.
NewUse it inside Claude and other AI assistants (MCP)Type a domain or paste a URL, then press Enter. Ranks, 12 monthly crawls and live crawler checks, all in one go.

What the check covers
Everything Common Crawl has on a domain
One search pulls the web graph, the monthly crawls, and the live site so you can see whether Common Crawl's data (and the AI models that use it) can reach you.
Crawl history
How many pages Common Crawl captured in each of the last 12 monthly crawls, read live from the Common Crawl index.
AI crawler access
Whether CCBot and 14 other AI crawlers are blocked in robots.txt (both historically and live), plus a firewall test from Cloudflare's network.
CC Visibility Score
A single 0–100 score based on link authority in the web graph, crawl presence, and crawler access, with the factors that pull the score down.
MCP server
Use it inside Claude and other AI assistants
Connect this checker to Claude, ChatGPT, Cursor or any app that supports MCP, then ask in plain words, like "Is example.com in Common Crawl, and does its robots.txt block AI crawlers?" The assistant gets the same data you see on this page.
Free, no sign-in or API key. Remote MCP over Streamable HTTP.
Claude
In claude.ai or the Claude app, open Settings, then Connectors, and choose Add custom connector. Name it Common Crawl, paste the URL and click Add.
Claude Code
Run this in your terminal:
claude mcp add --transport http ccrank https://ccrank.aiseo.com.my/mcp
Other AI apps
In ChatGPT (developer mode), Cursor, VS Code and other MCP clients, add a remote MCP server and paste the URL.
