Canonical tag tools
Check, generate, and validate canonical tags. These tools are on the way — here is what to expect.
A set of free canonical tag tools to make it faster to check, generate, and validate rel=canonical tags without leaving the page — a live-URL checker, a tag generator, an HTML validator, a bulk checker for auditing many URLs at once, and an hreflang tag generator.
Canonical Tag Checker
Enter any URL and instantly see its canonical tag: whether one is present, whether it is self-referencing, whether it uses an absolute HTTPS URL, and whether the page or its canonical target redirects.
LiveCanonical Tag Generator
Paste a URL and get a clean, copy-ready rel=canonical link element for your HTML head, plus the equivalent HTTP header version for PDFs and other non-HTML files.
LiveCanonical Tag Validator
Paste the HTML from your page head and the validator finds the canonical tag and flags the common problems: missing, duplicated, relative, non-HTTPS, or pointing somewhere it should not.
LiveBulk Canonical Checker
Check a whole list of URLs at once and export the canonical tag found for each, so you can audit a site section or a migration in a single pass.
LiveHreflang Tag Generator
Enter your language and region URLs and get the full reciprocal set of hreflang link tags, including x-default — the companion signal to a self-referencing canonical on international sites.
