As more and more sites get hit by the Penguin, bloggers are at their wits ends to figure what works and what does not. Another quest is for that exact red mark which should not be treaded. The topic and area itself demands extensive content but for now I will share some of the interpretations with you which in my humble opinion suffice.

Interpreting Matt Cuts…
Search to the end user, according to Google must provide in-depth information against a keyword. This means that each article or post which you write should be well, well and well researched by touching all encompassing areas that could be termed relevant.
A few example of such content can be found here and here to have an idea what an ideal case scenario post might be like. I do not claim to be an authority here but this is an intuitive understanding with a couple of years of experience in the world of content marketing.
