canonical link per pageThe same page is often reachable at several URLs — with and without www,
with tracking parameters, with a trailing slash, over http and
https. A canonical link names the one official URL, so crawlers
don't treat the variants as separate, competing pages.
Inside <head>, pointing at this page's preferred absolute URL:
<link rel="canonical" href="https://yourdomain.com/this-page">
| Do | Don't |
|---|---|
| Use an absolute URL (full https://…) | Use a relative path |
| Point each page at itself | Point every page at the homepage |
Pick one host (www or not) and stay consistent | Mix http and https |
On a page that's genuinely unique, the canonical simply points to its own URL — that's correct and expected, not redundant.
