I have a site in the pet bird niche that gets about 300 unique visitors a day right now. It's not approved by AdSense, because it doesn't have sufficient content. It has two really long pages. How many pages do I have to have for it to get approved? Or, it just because I have blank pages? How much could I expect to make on AdSense per day with this if it was approved? I also have a bodybuilding website I want to try to build, as well as a cat site. What kind of CPC could I expect on these niches? Do people make money in AdSense anymore? I need solid information before I invest a lot of money.
