The free SEO audit: what it checks
Up to 10 pages of your website, free, with what to fix first.
Type your website's address on the free audit page or, with your account, in Audits, where you also see every audit you've run and how many you have left today. We read your sitemap (or your home page and its links), respect your robots.txt and check up to 10 pages (with Pro, up to 100; with Agency, up to 500).
| What it checks | What's correct |
|---|---|
| noindex | That the page doesn't ask Google NOT to show it (in the HTML or in the header). |
| Title | That it exists and is between 30 and 60 characters. |
| Description | That it exists and is between 120 and 160 characters. |
| H1 heading | Exactly one, saying what the page is about. |
| Canonical | That it points to the right version of the page. |
| Language | That the page declares its language (lang). |
| Images | That they all have alternative text (alt). |
| AI crawlers | That your server lets in the ChatGPT, Claude and Perplexity crawlers your robots.txt allows. |
AI crawlers: what robots.txt doesn't tell you
A site can say “come in” in its robots.txt while its server, its CDN (Cloudflare…) or a security plugin answers GPTBot or ClaudeBot with an error or a challenge page. It doesn't show up in any dashboard, and ChatGPT or Claude can't read or cite you. The audit requests your page once with each crawler's exact name and compares it with what a normal browser gets.
- Fix: your robots.txt lets a search crawler in (or one that visits when someone asks) and your server blocks it.
- Review: the server also blocks a fake Googlebot (it probably checks the crawlers' real IPs, so the real one may get through), or serves it a much smaller page.
- You block it: your robots.txt tells it not to come in. That's your call, and we don't test it.
- Not tested: your site also stops a normal browser without JavaScript, so there's no way to tell.
Each crawler links to its company's official documentation. How our own bot works: seoclave.com/bot.

The first audits of each day on your plan go deep; the rest that day check 10 pages. A deep audit can take several minutes: you can close the page and come back later from Audits. They run in their own queue, so they never hold up the others.
Without an account, if you audit the same site twice within 24 hours we show you the same report and it doesn't use your quota. With an account, every audit is new: handy to check a fix right away.
