Optimizing Free Sites

[Halfdeck]

I assume "200" was not a typo and you really didn't mean "20"...20 is what I typically use.

Nah, by "200" I mean a truckload of recips. IMO 20 is too many but your mileage may vary.

Should you always no follow your affiliate links?

No, but if you want your free site pages indexed in Google, not nofollowing aff links can cause problems for two reasons: 1) Google doesn't like to see aff links that pass juice, since they're not editorial 2) Less juice flowing to your free site pages.
