PPC or fixed cost advertising.
They have me managing their Adwords campaigns but see this as a fixed cost as I give them an idea of how much to budget, they then give me a final amount, and I get them as much traffic as I can for that money; no more, no less - they consider that as fixed cost, no surprises, no overspend, no hassle (for them)!
So, things like Google's new print media bid pricing will (I think) be used more by the media buyer than the employer (in recruitment advertising) but with better pricing possibly being the end result. This reduced cost of print media may not help the more traditional media buyers but does open up doors for those with a different mindset!
