Check your title, description and Open Graph tags in seconds

What the checker reads

Meta tags sit in the head of a page's HTML, invisible to a visitor but read by browsers and search engines before anything else loads. This tool pulls the live HTML for the URL you paste in and reads the title tag, meta description, robots meta, canonical tag and viewport tag directly, the same way a crawler would.

Why the details are worth checking

A title tag that runs past around 60 characters gets truncated in Google's results, so the words that matter most need to sit near the front rather than the end. The meta description doesn't influence rankings directly, but it's often the line a searcher reads before deciding whether to click, which is reason enough to write it on purpose.

The robots meta tag and canonical tag do quieter work. Get the robots tag wrong and a page you wanted indexed can sit outside Google's index without any obvious warning. Get the canonical tag wrong and you can end up telling Google that two separate pages are the same one, or that a page you care about is a duplicate of something else.

What this tool won't tell you

It checks one URL at a time, and it reads the HTML as served. A page whose meta tags are written in by JavaScript after the page loads can show a different result here, so treat an unexpected result as a reason to check the rendered page. The check also can't tell you whether the same title tag is being reused across fifty other pages on your site, because it never sees the rest of the site.

When to reach for something else

For a single page before it goes live, or for working out why a specific page isn't ranking the way you expected, this tool does the job in seconds. For auditing meta tags across a whole site, a proper crawler is the better tool for the job, and the technical SEO crawlers comparison covers the options for that scale of work. The SERP Snippet Previewer shows how a title and description will actually render in Google's results. The Meta Tag Checker guide walks through what each result on this page means in more detail.
