Theres 2 reasons why this might occur, though more that likely as a result of googles "smartpricing" program.
What this does is feed sites with what is perceived as having good traffic with good advertisers and bad with low cpc advertisers. Parking providers can be inadvertantly tarnished with the actions of their customers.
I can assure you that Namedrive are not getting greedy or anything like that, you are simply getting the same percentage though from a lower paying set of advertisers.
The same is to be said with any company (sedo included) that serves you a google feed.
The second reason is that Adword advertisers can also now opt out of their ads being shown on the advertising network outside of a clean search.
Unfortunately, like most things, the few are ruining it for the many. And i know for a fact that Namedrive are working hard to winkle out those parkers that send in bogus traffic and make false clicks. Its a tough job and a never ending battle stopping these fools from thinking that the ppc industry was born yesterday.
Obviously, as well as someone involved in providing a parking solution, I am (with several other ventures I am involved in) also an adwords customer and nothing is more annoying than to receive my report from google.... In fact i'll give you a real example .... Last month, we heavily advertised a UK construction training business at adwords, budget ยฃ500/month. Nearly ยฃ100 of my budget was spent on some bizarre sounding sites subdomains that bore no resemblence (or chance) to what product or service which we were offering. I mean, these sub domains were "/michaeljackson", "/bill_gates", "/war_in_iraq" etc etc. So, together with reporting this fools sites as a fraud, I opted out of our ads being shown on the network.
Thats the answer I am afraid friends.
