That's quite complicated for an algorithm if you'd ask me. 1 + 1 = 2 Would be a lot better than that one.
They will not show their algorithm but only gives guidelines and tips, much easier to understand and follow.
Google does not disclose its algorithm for site ranking , it only provides guidelines to get a better ranking so Ranking is a SEO's trial & error method. What works for a certain website may not work for an another. It keeps the ranking non manipulative and the professional SEO's in employment .........LOL
100% sure OP knows that he won't get an answer for this, nice way to increase his post count so he can post on the other forums.
From the amount of times this question gets asked here, I'm pretty sure that most people asking are expecting an answer.
