Free Canonical Hreflang Checker

Paste page HTML to inspect canonical and hreflang tags together. Find missing annotations, duplicate canonicals and obvious hreflang issues.

Why canonical and hreflang should be checked together

Canonical tags help indicate the preferred URL for a page. Hreflang annotations describe alternate language or regional versions. International SEO setups often use both, so reviewing them side by side can reveal configuration mistakes.

What this checker looks for

The tool counts canonical tags, extracts their href values, finds hreflang alternate tags, detects duplicate hreflang language-region values and checks whether the source contains an x-default alternate.

What it cannot prove

A pasted page cannot show whether the reciprocal hreflang annotations on other pages are correct. It also cannot verify HTTP responses, redirects or whether the URLs actually exist. Use this as a fast source-code check before a full technical audit.

FAQ

Why check canonical and hreflang together?
International pages often use both canonical and hreflang signals. Checking them together helps you spot missing tags and obvious consistency issues.
Can a page have a canonical tag and hreflang tags?
Yes. A page can have a canonical URL and alternate hreflang annotations. They serve different purposes and should be configured consistently.
Does this checker crawl pages?
No. Paste the HTML source of a page. The analysis happens locally in your browser and does not use an external API.
