Meta Tag Checker
Check a webpage's title tag, meta description, canonical URL, robots tag, Open Graph, and Twitter cards.
What is a meta tag checker?
A meta tag checker is a simple SEO audit tool that reads a webpage's HTML and shows you the tags search engines and social networks care about. The two most important are your title tag and meta description.
This tool also checks canonical URLs, robots meta tags, Open Graph tags (used for link previews on Facebook and LinkedIn), and Twitter card tags.
How to use this meta tag checker
- Paste the URL of the page you want to check.
- Review the title length (aim for ~50 to 60 characters).
- Review the meta description length (aim for ~120 to 160 characters).
- Confirm canonical and robots tags match your intent.
- Confirm Open Graph and Twitter tags exist so your shares look good.
Common use cases
- Check why a page is not getting clicks from Google.
- Verify a new landing page has a canonical URL and isn't set to noindex.
- Fix ugly social previews when sharing on LinkedIn or X.
- Audit a blog post title and description for truncation.
Frequently Asked Questions
What is a good title tag length?
A common guideline is around 50 to 60 characters. Longer titles can be truncated in search results, depending on device and query.
What is a good meta description length?
A common guideline is around 120 to 160 characters. Some results show shorter snippets, but this range tends to read well and reduce truncation.
Why is my meta description missing?
Some sites do not set meta descriptions, or they render tags dynamically with JavaScript. If the page blocks bots or requires client-side rendering, a simple fetch-based checker may not see the final DOM.
What is a canonical URL tag?
A canonical tag tells search engines the preferred version of a page when multiple URLs have similar content. It helps reduce duplicate content issues.
What are Open Graph and Twitter card tags?
They control link previews on social platforms (title, description, image). Without them, platforms guess and previews can look wrong or inconsistent.
