Getting Different PA/DA for 'www' and 'non-www'?

[WhiteboardCreations]

Can anyone explain why we're seeing different DA/PA for our website when viewing in OSE for 'www' and 'non-www'? This is for our site whiteboardcreations.com

Our 'www' is resolving at DA 37 | PA 47
Our 'non-www' is resolving at DA 37 | PA 44

Thanks! - Patrick

Hi! The page authority is different because those are actually two different URLs. You probably have more backlinks going to one URL than to the other. If it's not already set to redirect from one version to the other site-wide, I'd set that up (tethering right now and don't have much bandwidth to check).

From what I have personally seen with Moz is that it calculates DA based on the whole domain and passes the same DA to all of the sub domains of the site. So that would explain why the DA is the same for both urls, since www is considered a sub domain.

For the PA what it means is that more than likely your site is accessible from both the www and non www urls. This creates duplicate content, but at the same time it splits the page's authority as well. The reason being is that Google will see them as two different pages, but they have the same content. Then also some users might enter with the www and some without. Then those people might want to link to your site, some will use the www and others will not use the www. So you are basically creating two different link profiles for the site.

I would add a canonical tag to the site if you are going to keep it this way, then it will be known to search engines which site is the preferred one. Ideally, you should put a redirect and choose to go with using the www. or not using a prefix at all, but not both at the same time, then add a canonical tag too for good measure.

Thanks, Keri. I suspected that.

Thank you for the explanation, Prestashop. I'll have to look into this ASAP. We thought we had set all of that up, but now seeing something went awry.
