I joined Dynadot at the commencement of .tel domains and tried my luck to get some domainers to register a domain with them.
Maybe it’s because they just don’t care about expanding via affiliates, the system might be a little buggy or not so affiliate friendly in that once the referred friend signed up an account with them, even if they have clicked through your affiliate link to register the domains at Dynadot, the newly registered domain and its commission will not be credited to you at all.
Therefore, make sure you send your friend or site visitors the affiliate link before they register the account with Dynadot. So, basically, they should register their account through your affiliate link. The other way won’t work for sure, but still I’m not sure if it works in this way.
Feels a little fishy with Dynadot domain registration affiliate program and totally not worth the while.
