This is a SWEET 11 page PDF! Now I know that it is talking about IM updates around the beginning of 2014 but the techniques, I believe, can be utilized today and in the coming years. Some things I did not know that are in the PDF:

-Chartelligence is a google chrome extension allowing you to overlay data onto graphs in google analytics and quantcast.

-Algoroo is used to track google algorithm changes by monitoring turbulence in rankings of 1000's of keywords.

-Overlooked a tool called Fruition that is used for doing quick google penalty checks.

-Siteliner is a free service allowing you to quickly identify key on page problems such as duplicate content, broken links and page power.

-Screaming Frog used to identify duplicate content and other on page errors.
