trop... Here's an example of the kinds of free sites you can build and receive traffic back from.
This is one of my hundred or so... You just gotta keep building 'em.

Once they are built, you just leave them there. Don't waste time updating or changing links... just move on and do more. Always more. You could use the lists I have listed on there as a guide if you wish. Most of them are good at listing you, and they do send traffic back. In terms of the content you see there... Most of it I purchased (licensed), but some of it is provided by the programs I am pushing.
