PPC feeds, anyone else use them ?

[theboyzlist]

I run a new gay LL, http://www.theboyzlist.com

i used a script "K-Links" for my main directory which i have to say is a very good script.

It came with optional use of using PPC feeds at the bottom of categories.
Iv been using these and yes, its generating me some nice income.

The company im using is called SearchFeed.

So the real question is, has anyone else here used this kind of marketing, and if so, what results have you had ?

Or ? Is it so bad i should scrap it ?

I look forward to your replies!
