Canonical Tags

3 min readUpdated 9 August 2026
A canonical tag tells search engines which version of a page is the real, preferred one. It prevents URL variations from being treated as separate, duplicate pages.

Why they matter

Search engines can read different URL variations as separate pages, for example yoursite.com/about-us and yoursite.com/About-us, even though they show the same content. The canonical tag resolves that by naming the one true URL, so all the ranking signal points to a single page.
In your page's source it looks like this: <link rel="canonical" href="https://www.yoursite.com/about-us" />.
On Limecube this is fully automatic. A correct canonical tag is set on every page for you, there's no canonical setting anywhere in the SEO Manager, and nothing to configure. It quietly prevents duplicate-content issues from things like capitalisation or trailing slashes.
