Seeing as we list all the Clickbank products (and there are thousands) we can't buy and review every single one of them. So we have come up with a different system of evaluation. We use statistical indicators. They include an estimate of the product's refund rate, the site's rating on 3rd party security sites, the site's popularity and of course the user feedback. We plug in the data and the system gives the product a rating. In this way we can rate ALL the products in an unbiased way. We don't just make up a rating like most so called review sites.
