- Links - broken internal and external links, orphan signals and anchor text distribution.
- Performance - load time, page size, compression, caching headers and render-blocking assets.

SEO checker vs. SEO audit
An SEO checker runs quick page-level checks and returns an instant pass/fail summary. An SEO audit goes deeper: it fetches the page, checks indexability, metadata, headings, canonicals, structured data, links and performance, then scores every finding and explains how to fix it. This free SEO checker runs the full audit, so you get checker speed with audit depth.
Who should use the free SEO checker
- Website owners who want a clear SEO score without paid software.
- SEO specialists validating a page before or after publishing.
- Developers checking technical signals after a deploy.
- Agencies running first-pass diagnostics for clients.
Frequently asked questions
What is an SEO checker?
An SEO checker scans a web page for search optimisation problems such as missing titles, broken canonicals, heading issues and slow load times, then reports exactly what to fix.
Is this SEO checker really free?
Yes. The SEO checker and every report it generates are free to run, with no credit card and no signup required to start an audit.
Does the SEO checker work on any website?
It works on any publicly reachable HTTP or HTTPS page. Password-protected pages, localhost and private network addresses cannot be checked.
How long does an SEO check take?
Most pages are analysed in a few seconds. Large or slow pages can take longer because the checker fetches the page, its resources and related SEO files such as robots.txt and the sitemap.
Can the SEO checker find hidden SEO problems?
Yes. It checks indexability signals, canonical conflicts, duplicate metadata, structured data errors, broken links and performance issues that are easy to miss in a manual review.
Do I need an account to use the SEO checker?
No account is needed for a first audit. Creating a free account keeps your reports together and raises the daily audit allowance.
