Of all I've tried, I like SEDO the best. Like all the services, SEDO seems to have all the same fluctuations in click revenues at the moment.
However, to me, SEDO's two biggest weaknesses are PARKED's strongest ones -- the ability to add HTML text and pics to the parked domain's page and a huge photo database.
SEDO's pictures are not only dated but fail to have any relevance to the domain name in many cases. What does PARKED have? Five thousand photos? And what does SEDO have? Maybe 100?
SEDO, I love y'all, but no improvements in the last two years makes me wonder if no one cares any more, except maybe on the auction side of your business. I'm one of your biggest fans, but have you given up? Please spend a few dollars and outsource it if you don't want to do it yourself.
Oh, yeah, I forgot -- Most of the functions related to putting domains into Portfolios do not work.
