I see big improvement on my RPC since widgetbucks started deploying the site category features, as of now the highest RPC I’m receiving is .33 and the lowest is .15 which is far better than .03 rate.
Widgetbucks is one of my highest online income generator aside from adsense. I’m currently earning at least 8$ per dayfrom one site alone.
I’m also thinking joining Project Wonderful as I read some good feedback from Macuha.com . 😀
