You can try sedo.com, but other DP domainers will tell you what's really the best. I'm not sure if Sedo is.
IMHO, the "best" parking service depends on what names you have. Only have a few? I would try sedo, namedrive or 1plus (if you have adsense). have a couple hundred with decent quality traffic? parkingpanel, parked have more than a couple hundred getting really good traffic? then maybe imonetize, trafficz, revenuedirect e.t.c have thousands and thousands with mega traffic? then maybe go direct to skenzo or google
Nobody mentions DomainSponsor? Probably the biggest parking company in the business. I personally use iMonetize but have and use a lot of the others. Depends on traffic volume, a lot of places screen people, you need to bring some traffic to the table if you want to park names. There is a high rate of fraud in the industry and companies are getting more and more cautious. As stated some companies do better for different types of traffic. Fabulous used to be the absolute best for gambling for instance. DotZup has a great reputation for ultra generic .coms. I recommend trying a few if you actually have some good names with traffic and see which produces the best results.
Parked.com is the way to go. Trust me. Sedo has nothing on them. Use me as a reference when signing up at parked (ChrisB72) and youll get 10% more in your payouts. I make $200 a week at parked.com.
Parked you need domains with good quality traffic in order to be approved. I got rejected 3 months ago. So I'm stuck at Sedo.
