I have a blog that I write about both sports and music. Since I have more than 1 niche, can I still sign up for programs like Chitika,adbrite, and clicksor? I only know that adsense doesnt allow it.
AdSense allows multiple niches. With AdBrite, each blog will have to get its own ad code. Not sure about Chitika, clicksor but I'm pretty sure they have no problem w/ multiple niches. Sounds like you should wait on getting some more traffic though, before trying to monetize your sites too much at this point.
