Hi, I have basic knowledge about on-page and off-page SEO. I am a php developer. I have couple of website and I am using Google adsense. I only make 2-3$ per day. I looked at BHW website and noticed people are making $$$$$$ of money. I think, there are other ways to make money than Google adsense. Could you please guys tell me which other methods I can use to make money? What are available sources? Thank.
