Canonical URL checker

Every page on your site needs a canonical tag. The tag tells search engines which URL is the main one. If a page has no canonical tag, search engines may index the wrong URL. If the canonical points somewhere else, two pages may compete in search results and dilute your ranking. This tool fetches a URL and shows the canonical tag it finds. It also flags cases where two pages share the same canonical, or where a page with extra info in the address bar points to the wrong main page. Run this check after any site migration, URL change, or CMS update to make sure your canonical tags are still correct.
