Different levels of PA without "www"?

[maty]

Hello Guy´s!

The last days I have been surprised to see that the levels of PA, mR, and mT vary when it is or not  the "www" in the URL:

1. http://patagonline.com/viajes-argentina

2. http://www.patagonline.com/viajes-argentina

Both URL's correspond to the keyword "viajes Argentina"  our incoming links...

In this case, it´s convenient to do a 301redirect from URL 1 to 2?

Thanks a lot for your help!!

Hi Matias

Yes, indeed.  You have 2 versions of your website live there, the non-www version and the www version.

Both will differ in terms of Domain Authority, Page Authority etc as they will have different authority attributes, different link profiles, different visitor levels etc.

One of these sites is duplicate and potentially harming. I'd absolutely recommend 301 Redirecting (or the equivalent) one to the other. When you have done, use Google Webmaster Tools to inform Google which version you'd prefer to have included in its search results.

Up to you which one, doesn't matter at face value. Though do check which one is currently appearing in search results for brand and non-brand search terms the most and which has the highest quality links pointing to it, then 301 the weaker site to the stronger.

Simon is correct, SE's see this as 2 different sites, you are splitting your rank.

301 one to the other and you should get a boost over the next few weeks
