If your answer to the above questions is yes, then I recommend using Adsense. Adsense is the ad network of Google. There are a lot of online entrepreneurs who are earning decent incomes through this ad program of Google. In fact, some even became millionaires because of this.
But having this kind of income is not a walk in the park. This needs hard work and dedication to earn big residual income in Adsense. This is the truth that most who tried Adsense failed because they were not able to realize it is not easy to make money with Adsense. There are a lot of self-proclaimed gurus who are preaching it is easy to make money with Adsense and many are fooled with it.
