How to spot trends early using Google (free course)

In the course you will learn useful Google tools to spot trends as well as how to piggyback on the existing demand created by a trend.
I was too cheap to buy a platform to host the course on (Podia, Kajabi, etc..), so I built one myself where users can mark lessons as completed, and comment (through disqus).
Full disclosure: I own a startup in the space (Treendly). That means that I eat and sleep trends, so I think you will learn a thing or two, hopefully.
Enjoy!
