Free SEO Checker
Paste any website. In about ten seconds you get a health score out of 100 and 25 real checks: security, crawlability, on-page tags, speed, broken links and domain setup. Every item says what's wrong and how to fix it.

What gets checked, and why
Twenty-five checks in six groups. Each one is something a search engine or a visitor actually runs into, and each comes with a fix.
Security
HTTPS, the redirect from http:// to https://, and the headers that tell browsers to stay on HTTPS and not to embed your site in someone else's frame. Google has used HTTPS as a ranking signal since 2014, and Chrome marks plain HTTP sites as "Not secure".
Crawlability
Whether robots.txt exists and isn't accidentally blocking everything, whether there's an XML sitemap, whether the homepage carries a noindex, whether a canonical tag is set, and whether www and non-www land on the same version. Any one of these can keep a perfectly good site out of the index.
On-page
Title length, meta description, a single H1, the mobile viewport tag, the language attribute, Open Graph tags for social sharing, structured data, and how many images have alt text. These are the basics that every SEO audit starts with.
Performance
Time to first byte (Google recommends under 600 ms), the size of the HTML document, and whether responses are compressed. This is a single request from one location, not a full Lighthouse run, but it catches slow servers reliably.
Links
We take a sample of internal links from the homepage and check each one's status, so you find 404s before visitors do. On HTTPS sites we also look for resources still loading over http://, which browsers block or warn about.
Domain
Registration date and expiry from the public RDAP registry, and whether email authentication (SPF and DMARC) is set up. Expiring domains and spoofable email are the kind of thing nobody notices until it's a problem.
How the score works
Each check has a weight (HTTPS and indexability count more than a missing lang attribute). A pass scores full weight, a warning scores half, a fail scores zero, and informational items don't count. The result is a percentage. A is 90+, B is 80+, C is 65+, D is 50+.
Questions
Why not Domain Authority?
Because we'd be making it up. DA and DR come from crawling billions of pages to count who links to whom. We measure what we can actually see. If you need an authority metric, Moz's free checker is the honest source.
Does it check every page on my site?
No, the homepage plus a sample of the links on it. A full-site crawl is on the roadmap.
Is it free?
Yes. 10 checks every 10 minutes per IP, no account.
