Advertising For Cash. While still building your business!

When researching internet advertising, I have found it very difficult to not get distracted. There are so many offers and leads to explore. I am leaning now to stay focused more on one or two ideas that I am working on, and if I see one that is interesting, I write it down and come back after I complete my original research.
Yesterday, I came across a couple of services that may be of help bringing in some money for free.

They all seem like good programs. I reviewed them online and signed up for each of them. They are free, but there are options to buy in. Good ones I think too. If your already rich, they won't really make a difference to you, but if your just getting your feet wet in the internet marketing business, then these may be good learning tools.
Oh, Squidoo.com is a good way to start for free. Some people make up to 500 dollars a day from their lenses they create online. Oh, and did I say its free too!
