It is quite easy actually to say if an affiliate is going to be good!Be on the lookout for the following signs:
1.Observe if he/she is visiting SFI every day.I could say that this is the MOST important factor.
2.Do they buy regularly items at TripleClicks...but don't rely too much on this...some affiliates are good without much of buying.
3.then look also for those who also ALWAYS learn and ask you questions.
If you support those you are HOME and RIGHT.
