Wow, lots of great posts out there today. Sharing as fast as I can but can't keep up.

Here is a good one from Moz by Gianluca Fiorelli.

The Myth of Google's 200 Ranking Factors - Moz

I am not writing this post to attack people like Brian Dean, who, in August, published an update to the "complete list" that Backlinko first presented in 2013. Brian, whom I esteem, created an effective piece of link bait (as the 318 linking root domains it earned testify).

I am writing this post because those lists are, quite simply, useless and dangerous, and because I hope to help people—especially the newer generations of SEO—understand that a definitive and complete "List" of Google's ranking factors does not exist. Moreover, some of the factors that appear in those lists:

Are myths;
Are correlation factors and not causal factors;
Are presented just to reach the number of 200.

Good stuff. Head over to read the rest.
