RE: Do "Proven Buyers" Really Exist in Affiliate Marketing?

This is a Marketing or Sales term. It only means that the people have paid for something before and there is no guarantee that they will buy again or buy your product. You will see this term again in other places I have seen it many times doing research on solo ad providers, they claim to have a buyers list over just a list of subscribers. It can be a more productive list but as a Marketer you kind of want to take any statements you see on sites like this with a grain of salt because it is just a way to get your attention and hopefully more of a chance of you signing up and spending mone.
