Grade your site’s internal linking in under 2 minutes.
Free. No install. Works on any site — Shopify, WordPress, Webflow, Wix, Squarespace, Framer, Ghost, or custom.
See your site the way AI crawlers do. ChatGPT, Claude, and Perplexity don’t run JavaScript — they read the same raw HTML Crawlmouse grades, the view Google crawls first. Links that need JavaScript are invisible to them.

What is internal linking?
Internal links are the links from one page on your site to another. Together they form a graph that search engines and AI crawlers follow to discover and rank your pages — a well-connected graph means more of your pages get found.
A–F letter grade
One score from four parts: orphan pages, click depth, anchor-text quality, and structure.
How is the grade calculated?
- Orphans (40%) — pages nothing links to.
- Click depth (20%) — how far pages sit from the homepage.
- Anchor diversity (20%) — descriptive vs. vague link text.
- Structure (20%) — how well your links concentrate importance.
Peer benchmarks
See how your internal linking compares to thousands of similar sites.
Why compare?
A grade means more in context. Benchmarks show whether your internal linking is ahead of or behind sites like yours — and where the easy wins are.

Frequently asked questions
- What is Crawlmouse?
- Crawlmouse is a free tool that crawls your website, maps its internal links, and grades the structure — orphan pages, hub strength, click depth, and anchor-text diversity — as a single A–F score you can share.
- Is Crawlmouse free?
- Yes. You can audit any site for free, with no account and nothing to install. A Pro plan ($19/month) adds CSV export and higher limits for people who audit sites regularly.
- Do I need to install anything?
- No. Crawlmouse runs in your browser — you paste a URL and it crawls the live site for you. There's no desktop app, extension, or download.
- What does the grade measure?
- Four things: orphan pages (pages with no internal links pointing to them), click depth (how far pages sit from the homepage), anchor-text diversity, and overall structure quality — how authority flows through your internal links.
- Which platforms does it work on?
- Any website — Shopify, WordPress, Webflow, Wix, Squarespace, Framer, Ghost, or fully custom. Crawlmouse reads the rendered HTML, so the platform doesn't matter.
- Can AI crawlers like ChatGPT and Claude see my site?
- AI crawlers such as GPTBot (ChatGPT), ClaudeBot, and PerplexityBot don't run JavaScript — they read your raw HTML, which is exactly what Crawlmouse grades. If your internal links only appear after JavaScript runs, those crawlers can't follow them. Crawlmouse shows you the site they actually see.
- How long does an audit take?
- Most sites finish in under two minutes. Larger sites with hundreds of pages take a few minutes — and you watch the link graph build in real time while it runs.
