it took me 3 months to earn my first check of 107.40$ and then i realized that i'm getting about 80-100 clicks/day but my ads are not showing top paying keywords.
so i changed content, added few new pages with good content and found that now more image banner ads are displayed and more content relating to top paying keywords are shown and even clicks have gone upto 100-120/day.
but still i'm making same amount of money or sometimes even less? why?
