Free SEO site audit
Our crawler visits up to 50 pages of your site and checks them against the rules of the full Umbrellum site audit. You get a health score and every issue, grouped by severity, with the affected URLs.
Free and unlimited: does not use your weekly runsWhat the free audit checks
It starts at the address you enter, reads robots.txt and your XML sitemap, and follows the links on your pages like a search engine, up to 50 pages. It obeys robots.txt and its Crawl-delay, and slows down when your server asks it to.
Every page is checked for broken internal links and redirect chains, titles and meta descriptions (missing, too long, duplicate), H1 and heading structure, canonical tags and their targets, noindex pages in the sitemap, hreflang sets, thin and duplicate content, images without alt text, structured data, mixed content and more. Links to other sites and images are checked too, up to a limit per audit.
How to read the result
Critical issues hurt your visibility directly, such as pages that do not exist and links that lead nowhere. Warnings are worth fixing soon. Notices are good to know, but do not lower the score. The health score is the share of indexable pages without a critical issue or a warning.
Fix issues in templates first: a problem in your menu, header or footer shows up on every page and is fixed everywhere at once.

Frequently asked questions
Is the site audit really free?
Yes. It runs on our own crawler without paid data, so it does not count towards your free runs. To spare the sites we crawl, one site can be audited a few times a day.
Why only 50 pages?
A free audit has to stay quick and gentle on your server. The site audit in the app crawls your whole site, compares every audit with the previous one, ranks the issues by the traffic at stake from your rankings and can run every week.
Does it see content that JavaScript adds?
No. Like most crawlers it reads the HTML your server sends. Links, titles or structured data that only appear after JavaScript runs are not seen.
Can I block your crawler?
Yes. It identifies itself as UmbrellumBot and obeys robots.txt: "User-agent: UmbrellumBot" with "Disallow: /" keeps it out.
