I'm new to the Amazon.com affiliate program and I have a price comparison website. One of the customers I refer to Amazon.com generates 99% of the referral fees for me. So will they cap this 1 customer or cut me off at some point? This customer always visits my website first, then clicks on a link to particular items on Amazon.com before making their purchases.
Further, I am going to try to refer some other high volume repeat customers to Amazon.com, who I know will probably purchase a large number ($25,000+ a month) from them. So I'm wondering if anyone knows or has any experience with this type of situation.
I've been in the Amazon Associate program since 2001 and I've never heard of an Associate being cut off for this reason.
They did recently impose some changes on how price comparison sites can work with them, as you probably know, which says to me they keep an eye on your sector. The situation you describe is ripe for kickbacks and under-the-table deals, and Amazon states in the Operating Agreement that incentives are not allowed. Even if you aren't offering an incentive to this customer, they might assume you are.
So if I were you I'd be working to get as many customers into the mix as possible so as not to give Amazon reason to believe something fishy is going on.
The tone of your post implies that these customers are known to you (perhaps associates?) and therefore this would be violate the Amazon Operating Agreement. If the products being purchased are for re-sale (the volumes suggest that this could be the case) then you're in even more trouble!...
