Where is the cash in blogging

I am trying to figure out "Social Spark", Izea" and "Pay Per Post". Sounds like a great deal, but also I am finding out that placing ad spots on your page for rent is where I am making money, not much, but better then all of the affiliates, and Google Adsense. Google Adsense is a joke as far as I am concerned, I make about a penny a day. Now with "Project Wonderful" Advertising;

buying advertising

selling ad space

Ads Flip are just for credits, and just for you to advertise throughout the internet for free on other blogs and pages just like EntreCard, Spottt and Banner Exchange.



These communities are great for just getting your links out there to better your PR (Page Rank). Below is a short note on how IZEA, Social Spark and Pay Per Post. The problem I am having is that I don't have money to start these programs. EntreCard, Spottt, and Banner Exchange are free programs. This is just my opinion on advertising.

Which earns the most money?

Does anyone know the statistics between advertising spots on your page, or advertising companies, or becoming affiliates with companies, or Adsense Google, which do you make the money off?I am curious as to find out which of these earns the most money, I've been doing most of everything to get traffic through my blog and I can be honest, the traffic isn't making money me any money. The ads through companies aren't making me any money and either is the Adsense Google making me any money. What do you think I am doing wrong? I've been trying most everyday to earn money with this blog, doing everything up to advertising, Adsense Google and all the others mentioned above. Whats my problem?
