Why we built this
Every SEO analysis tool we tried was either locked behind a signup wall, plastered with upsells, or gave vague advice like "improve your meta description" without telling you what was wrong. We wanted something different: a tool that fetches a page, parses it properly, and tells you exactly what's missing, what's too long, and what's wrong — in seconds, with no account required.
Meta Tag Checker started as an internal tool we used when auditing client sites. Once we realised how often we reached for it, we polished it up, wrote proper explanations for every check, and put it online for free. It's been running ever since, and it's still free — no hidden tiers, no "premium" version, no watermarks on the results.
Who's behind it
Meta Tag Checker is part of ModusOp, a platform for operations, bookings, and client management built for small businesses and agencies. We build free developer tools like this one partly because they're useful to us, and partly because they're a good way to give back to the web development community that we're part of.
The tool itself was built and is maintained by JWWD, a web development studio based in Australia. JWWD has been building web software since the early 2000s and runs the technical side of ModusOp. If you want to see more of what we do, follow the links in the footer or head over to the main ModusOp site.
Our other free tools
Meta Tag Checker is one of several free tools we run. If you found this one useful, you might like the others — all of them free, no signup, and designed for the same "get useful results in seconds" workflow:
- SSL Checker — check certificate validity, expiry, and the full trust chain for any domain.
- DMARC Dashboard — inspect a domain's SPF, DKIM, and DMARC records with plain-English explanations.
- Site Speed Check — measure real-world page speed and get prioritised recommendations.
- Broken Link Finder — crawl any site and report broken internal and external links.
