%refd is what % of total sales come from affiliates. lets say a publisher made 5 sales via his affiliates and made 20 by himself (25 sales total), the refd would be 20% gravity is approximately how many different affiliates are making sales for this publisher. everytime an affiliate make a sale, the gravity of the publisher is increased by 1.00. This amount decreases over 6 weeks, and is reset to 1.00 everytime the same affiliate makes another sale. So when you see a gravity score of 17.20, The only thing it means is that they have at least 18 different affiliates that made a sale in the last 6 weeks. Low gravity= low competition high gravity= most likely a best-seller product, but with ALOT of competition. +rep if it helped you pleease
yes, but that's not all. Many merchant use easy click mate (or any other system) ti inflate their gravity number. It's a well know technique amongst merchants. All you need to do is to put many products under a single account. Let your affiliates promote EACH of these products, and gravity will explode! When an affiliate see this, he thinks wow, affiliates are making a tons of money, and he start to promote... and ALL other affiliates do this as well and hence fravity becomes even bigger. Shuuut! Don't tell anybody, this is ONE of the big clickbank secrets to make your gravity go to the rough and get to the top of clickbank rankings. Again, don't tell this everywhere...
It makes sense that online promoters would figure 'a way around' any measurement. Sounds like a system beating tactic that merchants 'in the know' will use to boost their sales. But, I quess most people do want 'sellers with smarts'.
