For parking your domains... You should take advantage of all the choices that you have because there are many places to park your domain this days, try them out for a week each and after that you can come to a conclusion on your own, as to who is better (which service converts more traffic and earns more money) for your domains. Sedo is pretty good if you have the right keywords for you and one thing good about them is that you can pretty much control your own keywords by self-optimizing them whenever you want, as often as you want.
For selling domains... Sedo and Afternic are both proven leaders, but personally I prefer sedo, that is because they are more globalized and that streches the market much further which is really great... More exposure and a broader audience!
Essentially, that is what I have done (tested my names at different sites) and report on at my website,
www.ppcincome.com . However, when you test your domains at Domain Sponsor, you need to give it more than a week. Your domains automatically optimize at Domain Sponsor, but the process takes anywhere from 2 days to 3 weeks for a domain. So, your portfolio will start to generate income right away, but you will not see the full potential for 3 weeks. Then you need a full week just to get a reasonable sample. In fact, each of the PPC sites that I have tested, I have tested for a minimum of 4 weeks.
The cool thing about auto-optimization (at DS) is that it learns from the websurfers what they are looking for. Sometimes, it is something you never thought of. Sometimes it is more than one thing.
I am in the process of testing DomainHop, but they are still improving their system. So, it could be a couple of months before I report on that one.
Domain Sponsor is working on some improvements that I am not allowed to discuss that will improve income by 50% to 100% over their already high rates of return. I know, because I am on the Beta test and my cpm is up 100%. For Domain Sponsor, you need 100 domains minimum (or some very good name, if fewer than 100 domains) and you need patience.
In my experience, for income, next best is Fabulous.com. They will optimize keywords for you and give you an increased revenue share (75%) for letting them optimize.
If you are focused more on selling your names, then I like Sedo and Afternic. But when names are earning PPCIncome like mine are on Domain Sponsor, I am in no hurry to sell. Sedo has brought me some very good buyers and I know that Afternic has done a good job for some of my friends.
I have a few names that do well on TrafficZ, so I keep them there. I have not tried Afternic PPC yet, but I may check it out later this year. It takes a lot of time and effort when you want to check a large number of names.
