What I used to do is share my Donald Trump articles on Facebook groups about Donald Trump as well as on my fan page about him. People are crazy about politics and most of the time Americans have the best CPC. Now it is all over saturated, but a new trend might pop up like Pokemon Go that you can put to use by sharing your content on related Facebook groups. But if you want to do something more longeterm that requires more skill, and dedication then learn just one thing... Content is king!
