I read so much that now I am more confused than ever. I want to start a travel blog (150+ articles) and monetize it with CPA and adsense. I'm a bit lost as to where to start. I know the travel niche is extremely competitive - every keyword I research is ranked as "high competition". The highest paying keywords are of course the "hotels in X" and "x travel insurance." I see three basic courses of action: a) A general travel blog covering countries all over the world b) A themed blog focused on one subject (for example, beer travel) c) A blog focused on just one country or city but still very in depth. Which would be the hardest to rank?
