Free Meta Tag Checker

How to use this meta tag checker

Paste any URL into this free meta tag tester to check meta tags instantly. Enter the full URL of the page you want to audit and hit Check page. The tool fetches the live HTML the way a crawler would, then grades each tag: green means it follows best practice, amber means it works but could be better, red means it is hurting the page. It also works as a meta description length checker and flags titles and descriptions that run past Google's pixel cutoff.

Fix reds first: a missing title, a noindex you did not mean to ship, or a missing viewport tag will cost you rankings and clicks on their own. Then tune ambers, starting with title and description length.

What each meta tag does

• The title tag is the clickable headline in search results, and the biggest on-page ranking signal after your content.
• The meta description is the snippet under the title. It does not rank the page, but it drives click-through.
• The canonical URL tells search engines which version of a page is the original, so you avoid duplicate-content dilution.
• The robots meta controls whether a page is indexed and its links followed.
• The viewport tag makes the page render correctly on mobile, which affects mobile rankings.
• Open Graph and Twitter tags control how the page looks when shared on social.

Why meta tags matter

Meta tags are how a page introduces itself to search engines and social networks. The title tag influences rankings and is the first thing a searcher reads; the meta description shapes whether they click; canonical and robots tags keep the right pages indexed; and Open Graph tags decide whether a shared link looks trustworthy. Getting them right is some of the cheapest on-page SEO work available.
