I was just explaining the other day about on page seo to a client and realised that I panned off alot of information to the fact that google changes their algorithm that often and is so complicated that its hard to keep up with it all so I decided to create a diagram that explains what they have been up to over the last 2 years and another to asign significants to it all.
Its important to note that the outcome of Google’s massive algorithm changes over the past two years is that it takes really great, fresh, optimized content produced on a regular schedule to convince Google that the source is relevant and authoritative and should therefore be returned as a search result.
This takes a lot of commitment, work and a strong focus on content marketing anyways heres the diagrams.

So all of these recent changes all point to the fact that google wants optimised content, producing fresh content for the keyword phrases that are driving organic search traffic is the way to go.
