Many parking co's pages are basically invisible to SE's b/c they don't pick up ads in the SERPs.
Parking companies want targeted traffic and clicks since advertisers are paying with the hopes of results (sales) not visitors to their sites. The best parked sites generate traffic primarily from type-ins which most fresh hand registrations won't get. Back links are ok with some parking co's (for instance, if you picked up a name on a drop that used to be a developed site and it still had old links out there). But I don't know of any company that will allow you to promote your parked name in any way. Just read through the TOS and you'll get the picture.
Best way to get traffic to a new domain you just registered is to develop it out into a website and put up some adsense.
From Namedrive's TOS:
Traffic:
Traffic on domains parked with NameDrive can originate from two sources only: type in (direct navigation) traffic and existing search engine results / expired traffic. All other types of traffic including bought traffic, traffic driven by PPC campaigns, traffic directed from hyperlinks are not permitted. If your traffic originates from any sources other than type-in and search engine traffic, it must first be cleared with NameDrive LLC.
Regular checks are carried out and NameDrive LLC reserves the right to suspend any domain from parking if the traffic on that domain is believed to be bought, generated or redirected in any way that contravenes these terms and conditions. Users may periodically view their parked pages to ensure they are correctly set up but are not permitted to click any of the advertising links.
