Auctions can be activated day or night.
In April 2015, Sedo opened up its marketplace auctions so that anyone could auction a domain name even with a reserve price.
Previously, a domain had to receive an offer that was converted into the starting bid in order to enter the auctions. Being on the Sedo auction page attracts a lot of eyeballs, so it is a popular tool.
These so-called “direct auctions” were an instant hit with sellers as 150 people paid $59 a pop to start a direct auction on the first day. Within a month, several domains sold for nice prices through direct auctions.
Today, Sedo announced that there is no longer an activation delay between placing a direct auction order and the auction starting. This means you can start an auction after business hours and on the weekend.
It costs $59 plus a 15% commission.
Sedo also touted some more sales from direct auctions:
I’ve kept a close eye on Sedo’s marketplace auctions since Sedo started the direct auctions option. It’s clear that most domains don’t sell, but that’s because they are poor domain names. Sellers need to think about what types of domains are liquid.
The examples above should provide clues as to what types of domains to list: short domains and one-word domains in various extensions.
