Open site Explorer Findings??

[Ideas-Money-Art]

On OSE, I am comparing two websites(A and B) and one has a page authority higher than the other (35(A) vs 36 (B)), but all the linking metrics are in favor for website A except for the linking C block (A has 11 and B has 12). The website B is ranked in page 1 for couple competitive keywords whereas the website A don't show up in the search at all. Why is that? Does B have better content and is more kw focused?

Using OSE, check the DOMAIN AUTHORITY of the sites that the back links are on. What I believe is that website B has better quality and thus higher domain authoritative back links than site A.

and/or

Website B has more back links than website A.

Also,

how well optimized are the websites for the keywords you are targeting? That's important.
