latey I earned 15k USD a month with adsense by ranking some trendy keywords, not many just 3-4.. it was a yearly big event in my country. 1 thing I love about doing this kind of keywords is that once you ranked, ppl is hardly to pull u down, because u spend time and efforts before the event kicked it. I'm sure I can hunt for the next wave, but what would be the best strategy? take superbowl2014 for example, u gt that domain - superbowl2014.com and made decent money, how would u continue to for the next? Good thing is my site on page 1 for its 'generic keyword' for that event, for example super bowl.
