I've come across a number of others, but 99% of them seem like a waste of time. Why don't you build your own website and add Adsense ads to that instead?

Hey, dude!

Just one advice.. Adsense your own website!! You can earn more. Don't waste your time on the revenue sharing website.

yup, have your own website using cms like wordpress. Its easy to use and can help you generate more income. Not only through adsense but also through many other ways
