Hello Guys, I was wondering something... I use the www version for my website, So I set the cannonicalisation and the 301 Redirect of non-www to www version. But I checked my website on MOZ (Open Site Explorer) and when I type in mywebsite.com I get 19 DA and 1 PA. When I typed in www,mywebsite.com I get 19 DA and 32 PA. So i would like to have some clarifications about how their domain authority and page authority system work. My PA of the www version is higher than my DA because almost all my link point to the www version and I do the 301 redirect. ? But how can I increase my DA if I focus on building backlink to the www version of my website ? Should I build link to the non-www version of my website to increase my DA even if I use the www version for my website ? If I build backlink to the non-www version, will it increase the PA of the www version since it's has a 301 redirect ? If I build backlink to the www version of my website will it increase the DA of my website ? Im really confused here so any help and clarification from you guys will be really appreciated. Thank You.
