MetaMonster
Free Meta Tag Checker
Paste any URL and audit its title tag, meta description, canonical, robots, and social tags in seconds.
How to use this meta tag checker
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.
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.
Frequently asked questions
What is a meta tag checker?
A meta tag checker fetches a web page and reads the tags search engines use: the title tag, meta description, canonical URL, robots directives, Open Graph tags, and more. It flags anything missing, duplicated, or outside recommended lengths.
What meta tags matter most for SEO?
The title tag and meta description have the most direct impact on how your page appears in search results. The canonical tag, robots meta, viewport, and language attribute keep indexing and rendering healthy.
How long should a title tag and meta description be?
Keep titles between 15 and 60 characters and descriptions between 50 and 160 characters. Google truncates by pixel width, not characters, so this tool also estimates rendered width.
Why does this tool say my page has no content?
Some sites render everything with JavaScript, so a plain fetch sees an empty shell. Search engine crawlers often struggle with the same thing. MetaMonster crawls with a full browser, so JS-rendered sites work there.
