I use Sedo for all of my domain sales, they have been the core service enabling my domain transactions. Sedo seem to be one of the most popular sites with big-money (over $50,000/name) transactions taking place regularly. Sedo’s domain appraisal service is definitely several notches above GoDaddy’s with a very thorough analysis of your domain, exposing the multitude of components that determine a domains price. My main complaint about Sedo is that their user interface is difficult to navigate and a bit archaic. Simple tasks that you should be able to do yourself oftentime requiring emailing support. A good example is if you list a domain and later put a website on the domain, you cannot edit your listing to reflect that the domain is being sold with the developed site. Instead you have to email customer service and have them change it for you.
So lately I have been trying to find an alternative to Sedo that could offer even more great exposure for my domains. I discovered Afternic which is another popular domain sale site. I found-out about afternic through buydomains.com which seems to be just a shell on top of afternic. Afternic is quite similar to Sedo however has a much more functional (albeit still a bit clunky) UI. It was much easier to add domains and change options or re-listing a domain. Afternic has more extensive promotion tools right out of the gate allowing you to opt for expanded promotion in trade for increased commission. Domains easy get lost in the millions of domains on Sedo so its nice to see this option available.
I have featured listings running on both Sedo and Afternic this month for freqentflier.mobi. I am looking to get an offer a bit north of $3,000. It will be interesting to compare the amount of traffic my domain listing gets on each service. This will provide some very useful information as to which service really has the most effective marketing program.
