Namecheap as I hoped have been fast to clarify that their affiliate program will work with their standard coupon codes.
Whether this was their initial intent, or a change to reflect feedback doesn’t really matter – it is now possible to promote Namecheap (as many have done for years without any monetary incentive), offer coupon codes, and make a small amount for each referral.
As niche marketers & affiliate marketers often have domain portfolios costing them hundreds, and in many cases $1000+ each year, a little extra income and recognition never hurts. (these aren’t hardcore domainers, just people who accumulate domains… and even sometimes build websites on them)
Namecheap Affiliate Interface
So you get an affiliate link… no sign of any kind of subid tracking or deep linking support, though it is possible deep linking works just sticking an aff ID on the end of each link.
Looks like there isn’t any click tracking either, though you can always use your own.
In some ways using a proprietary affiliate interface makes sense with Namecheap, as I am invariably using the interface on a weekly basis, but it is a little lacking in “affiliate” features, whereas they could probably integrate something like Hasoffers.com quite well (though that isn’t perfect).
