I only just got started building the list, so I've only got 6 people, but it definitely shows that its not in the size of the list!
My secret formula for anyone wanting to make their first sale (yeah Im talking like an expert now):
Be a friend that wants to provide the best help and material for your marketplace. Bond.
The sale came from my thank you page, so it's good to put your affiliate link there as the prospect could be hottest then is what I learnt.
So now hopefully will try and duplicate this. I managed to make my first sale by blocking out and promising to myself to ignore any new methods to make money online and stick to the pure proven basics, and just be cool.
