Rel canonical on every page of wordpress CMS website

[vtmoz]

Can we have rel=canonical across all pages of a wordpress CMS website? I don't know why same page has been as canonical but not for duplicate pages

Hi,

According to Dr. Peter J. Meyers "I’d say to use rel=canonical on the home-page, known duplicates, and any pages with parameters that could drive duplicate content, and leave the rest alone."

According to Yoast

"At Yoast, we have a strong preference for having a canonical link element on every page and Google has confirmed that’s best. The reason is that most CMSes will allow URL parameters without changing the content. So all of these URLs would show the same content:

if you don’t have a self-referencing canonical on the page that points to the cleanest version of the URL, you risk being hit by this stuff. Even if you don’t do it yourself, someone else could do this to you and cause a duplicate content issue. So adding a self-referencing canonical to URLs across your site is a good “defensive” SEO move. Luckily for you, our Yoast SEO plugin does this for you."

Yes for wordpress use rel="canonical" for all pages.

Thanks
