It sounds like they are just following google with thier smart pricing bs...
Here is something I learned a long time ago: anytime a company restructures something, it is rarely for the benefit of any other entity aside from themselves. i.e. I doubt there will be a perceptible difference in the amount that companies pay to advertise, but I bet the publishers take their lumps on payouts. I truly, genuinely HOPE I can come back here and eat crow, but the chances of my payouts on my niche quality traffic going up are about the same as starting a car by pissing on the engine.
Playing the devil's advocate I could have the perspective that publishers should not pay the price for advertisers not converting sales. Who's to say that the problem of poor performing sites is not equitable with bunk traffic?
Again, there is no change that doesn't benefit the SE. YPN will simply charge more to the advertiser and pay less to the publisher. That seems to be the way of the world these days; screw or be screwed.
Perhaps, But in the end, it will benifit the market as whole, advertisers that spend $200 a day consistanly, and don't get any conversions, will stop advertising, I certainly would, so i see thier point in doing this, If you bring targeted traffic, you will be fine, crappy traffic will pay the minimum, That's a fair enough deal imo.
