There are several points that are interesting that comes out of all of this...

* Links are still believed to be the most important part of the algorithm (approximately 40%).

* Keyword usage on the page is still fundamental, and—other than links—is thought to be the most important type of factor.

* Social factors aren't seen to be hugely important in the 2013 algorithm (only 7%), in contrast to the high correlations.

* Freshness of content and load speed are important.

* Like it or not, having the exact match keyword in the domain still helps, though is decreasing.

* Trust factor of the domains linking is very important (can be measured by algorithms like MozTrust, TrustRank, etc)
