Meta Checker URL

Validate URL-related meta tags like rel=canonical, og:url, and twitter:url against a page URL. This tool runs locally in your browser and does not fetch pages—paste the URL and (optionally) the page HTML.

Category: SEO · URL: /tools/meta-checker-url.html
No page fetching. Paste a URL, and optionally paste HTML source to verify canonical/OG/Twitter URLs.
Tip: If you paste example.com/page without a scheme, the tool assumes https://.
If you leave HTML empty, you’ll get a suggested URL meta snippet instead of a verification report.

FAQ

    
Does this tool fetch the URL and read my page?
No. It runs locally and only analyzes what you paste (URL and optional HTML source).
What counts as a match between the page URL and canonical?
The tool compares normalized absolute URLs (host casing, default ports, and fragments removed) and flags MATCH or MISMATCH.
Can it handle relative canonical URLs like /page?
Yes. It resolves relative URLs using <base href> if present, otherwise the page URL you entered.
Why do I see multiple canonical tags found?
Some templates output duplicates; most SEO setups should output exactly one canonical per page.
Should og:url and twitter:url match the canonical?
Usually yes—keep them consistent unless you intentionally want social previews to point elsewhere.
What if my page URL has tracking parameters?
The tool will note likely tracking params; typically your canonical should avoid them to prevent duplicate indexing.
Can I use this to check hreflang URLs too?
Yes. If you paste HTML that includes link rel="alternate" hreflang, it will resolve and display those URLs.
