Meta Tag Checker

Q: What is the ideal title tag length?

Google typically displays 50-60 characters. Titles longer than 60 characters may be truncated with an ellipsis. Place your primary keyword near the beginning for maximum visibility.

Q: What is the ideal meta description length?

120-155 characters. Google may truncate descriptions longer than 155-160 characters. Write a compelling summary with a call to action.

Q: Can I test localhost or staging URLs?

Staging URLs work if they are publicly accessible. Localhost URLs will not work because the server-side fetch cannot reach your local machine.

A meta tag checker audits any URL for title tags, meta descriptions, Open Graph tags, Twitter cards, canonical URLs, robots directives, and viewport declarations. OverlayQA's free meta tag checker extracts all meta tags, previews how the page appears in Google search results, flags missing or poorly optimized tags, and shows character counts. No account required.

What Are Meta Tags?

Meta tags are HTML elements in a page's head section that provide metadata about the page. They tell search engines what the page is about, control how it appears in search results, and define how social platforms display it when shared. The most important meta tags for SEO are the title tag, meta description, and canonical URL. Open Graph tags control social sharing on Facebook, LinkedIn, and Slack. Twitter card tags control the Twitter/X preview.
