Hmm! I think Adsence is great. I even created a program to create web pages for me. It will not make me rich. Selling my progams is better.
The secret is to give something for free, something useful. That brings traffic. Those who surf your site often see things of interest in the adds and when they check them out you get credit.
I have just started to set up sites that sell my stuff and plan many more.
If you get 100 hits plus /day I will discuss traffic trading (Links)
I am not going to say how much I earn only to say its not in the 10's /day yet
and you will find it varies from day to day.
Conclusion if 1 website earns $1/day create 1000 websites. I only have 3 so far but working on it. You have to cover hosting and a domain name. Freehosting is good but loads the page with their adds.
I will add one of my sites a simple layout
http://inkmon.org If anyone wants to use it as a templete go for it. It is only a simple 3 column table that I use Webmaxster to create. Anyway thats another story.
