Does it worth to list domains at GoDaddy auctions if listed at Afternic

up

short answer yes,
i sold a few domains listed on 7 days auctions at Godaddy
i have domains listed at both and the sale come from either place, even when the domain is registered at godaddy

imo you only need to list at Afternic. Names you have listed at Afternic will show up if you search at godaddy.com or auctions.godaddy.com anyway.

Agree with @andydotlol - once you list on Afternic, your name will show up as a premium name on the regular GoDaddy website if someone is looking for that name or similar name. Once on the GoDaddy auction site, you might make a sale, but GoDaddy auctions are typically other domainers, not end users. If you want end user pricing, Afternic is good enough.
