Browse this focused collection of free tools and checkers.
Explore free checker tools for metadata, redirects, sitemap, robots.txt, indexability, status codes, schema, and technical SEO validation.
Checker tools give fast yes-or-no answers to common SEO questions: Is my meta title right? Is my robots.txt blocking anything? Does this URL redirect correctly? Paste a URL and get a clear pass, warning, or fail in seconds.
Use them during QA before publishing, after a migration to confirm redirects, or when auditing a client site to spot issues that hurt crawling and indexing.
Most checks cover a single signal, so results are easy to read and easy to act on. Combine checkers with analyzers for deeper context or generators to build the corrected output.
This category groups together closely related free tools so you can move through a complete workflow faster. Use these utilities to audit, validate, and improve the signals that matter most in this area of SEO and website optimization.
Each page in this section is built to solve a specific problem, and together they make it easier to diagnose issues, confirm fixes, and keep your site aligned with search engine best practices.
Checkers validate individual signals like titles, meta descriptions, robots directives, redirects, HTTP status codes, sitemaps, canonical tags, schema, and page size.
Most checks complete in seconds because they test one focused signal at a time against the target URL.
Yes. Tools fetch the live URL and inspect the real response, headers, and markup, so results reflect the current state of your page.
