To other pages, with the same content, I need to put rel="canonical" in the link tag to prevent duplication.

<link href="https://example.com/original-page.html" rel="canonical">

My question, do I need to also put rel="canonical" in the original (canonical) page?

  • @w3dk Hi, I know my English grammar not good. But can you explain why you put word "also" after the "to". – Jose Alvin Rañola Mar 11 '16 at 14:21
  • Actually, the way you had it before ("also to") was OK, although it does read better the other way round ("to also"). I wouldn't have edited it if that was the only thing. Although I see I missed something on the first line, "with same the content" - that is incorrect, it should read "with the same content" ("the" and "same" reversed). – MrWhite Mar 11 '16 at 14:50

It's highly recommended. Google will probably understand what you mean without it, but it's highly encouraged to add it to all pages with the same content including the canonical page itself.

    There is actually a good reason for adding a rel="canonical" to the original/canonical page itself. If it is accessible with query strings and/or additional path information (PATH_INFO). eg. /original-page.html?foo=bar or /original-page.html/path/info, then adding the rel="canonical" will resolve any issues that could arise if these pages start getting linked to. – MrWhite Mar 11 '16 at 10:06
