Free SEO Meta Tag Checker
Paste any URL and see exactly which meta tags it has, which are missing, and which are the wrong length — then import them into the editor and fix them in place.
Fetches the page server-side and reads its tags. Public http/https pages only.
What does a meta tag checker do?
A meta tag checker fetches a page's HTML the way a search engine crawler does and reports the tags in its head: title, meta description, canonical, robots, viewport, Open Graph, Twitter Card and JSON-LD. It flags anything missing, and any title or description too long to survive truncation in search results.
How to use the SEO Checker
- Paste the full URL of a public page, including https://.
- Read the graded findings; each one names the tag and what is wrong with it.
- Import the tags into the editor, fix them, and copy the corrected head block.
Why use the SEO Checker
Private by design
No account needed. What you type stays in your browser unless you ask for an AI suggestion or name a URL to fetch.
Sees what a crawler sees
URLs are fetched anonymously and without running JavaScript, so the result is the HTML a basic crawler gets.
Rules, not opinions
Every check is deterministic. Run the same input twice and you get the same result.
Frequently asked questions
What does the checker look at?
It fetches the page's HTML and reads the title, meta description, keywords, author, robots directives, canonical link, viewport, charset, every og: and twitter: property, the html lang attribute, and any JSON-LD blocks.
Why was my URL rejected?
Only public http and https pages can be analyzed. URLs that resolve to private, loopback or link-local addresses are refused, because a server that fetches arbitrary internal addresses is a security hole.
Can I check a page behind a login?
No. The checker fetches the page anonymously, so it sees what a search engine crawler sees. A page requiring authentication will return its login page instead.
Does a perfect score guarantee rankings?
No. This grades the tags themselves — length, presence, and correctness. Rankings also depend on content quality, links, page speed and dozens of other signals no tag checker can see.
