Meta Tag Checker

What This Tool Checks

This free tool extracts and analyzes 18 important meta tags from any URL:

• Essential SEO tags: title, meta description, canonical URL, robots, viewport, charset, language, H1
• Open Graph tags: og:title, og:description, og:image, og:url, og:type, og:site_name
• Twitter Card tags: twitter:card, twitter:title, twitter:description, twitter:image

Missing or poorly configured meta tags can hurt your search rankings and social sharing. Use this tool to quickly identify gaps.

How to Read the Results

• Missing (red): the tag is not in the HTML the server returned. Title, meta description, canonical and viewport are the four to fix first.
• Too short / Too long (amber): the title is outside 30 to 60 characters or the description is outside 120 to 160. The tag works, but the snippet may be cut off or leave space unused.
• Canonical URL: should be the page's own address unless you mean to point search engines at another copy. A canonical that points somewhere else by accident takes the page out of the running.
• Robots: a value containing noindex keeps the page out of search results. A missing robots tag is normal and means index, follow.
• Open Graph and Twitter Card: these do not affect ranking. They decide the title, text and image of the card shown when the URL is shared. See it laid out in the Open Graph preview.

Frequently Asked Questions

What meta tags does this checker read?

Eighteen tags from the HTML the server returns: title, meta description, H1, canonical URL, robots, viewport, charset and language, six Open Graph tags (og:title, og:description, og:image, og:url, og:type, og:site_name) and four Twitter Card tags (twitter:card, twitter:title, twitter:description, twitter:image).

How long should a title tag and meta description be?

This tool marks a title of 30 to 60 characters and a description of 120 to 160 characters as good. Search engines cut off by pixel width, not character count, so treat those ranges as a guide: put the words that matter first so a shortened snippet still makes sense.

Does it see tags added by JavaScript?

No. It reads the HTML as served, the same first response a crawler gets, and does not run scripts. If a tag shows as missing here but appears in your browser's inspector, it is being added on the client, and crawlers and link previews that do not render JavaScript will not see it either.

Is a missing meta description a problem?

It will not stop a page from ranking, and search engines often write their own snippet anyway. A written description gives you a say in what appears under your title, and it is what most social platforms fall back to when og:description is missing.

Can I check meta tags for many pages at once?

Not on this page, which checks one URL at a time. The SEO Score API audits a URL in one call and has a batch endpoint on paid plans; the free tier allows 20 audits a month.
