Adify writes, “Over the last twelve months, there’s been a lot of attention on a new category in the online advertising ecosystem – the ad exchange. Acquisitions by Microsoft (ADECN) and Yahoo! (Right Media) and new offerings from Doubleclick reinforce that there is a real role for ad exchanges. It is a mistake to overstate this role, especially in reference to other parts of the advertising ecosystem. Historical analogy demonstrates exactly what the strengths and weaknesses of exchanges will be – can drive prices lower but require very knowledgeable buyers staying informed about all the factors influencing “asset” value. Vertical Ad Networks seem to be launching daily and the reason is that a quality vertical ad network is like buying into a mutual fund, rather than directly on an exchange. The vertical ad network builder is the mutual fund manager and drives value for themselves and their advertisers by tracking all the details and complexity in managing the publishers to deliver a high performing publishing community that efficiently and expertly reaches your target audience. “
