Publishers out there, how are you currently allocating your inventory?
Weighting - This is setting the weight of each advertiser/campaign. For example, you weight Network A with a weight of “3″, and Network B with a weight of “1″, Network A is sent impressions three times as much as Network B. If you’re doing this, how are you deciding what weights to set? How often are you changing it?
Percentage - This would be deciding on a percentage of inventory to send to each network.  Same questions here, how often do you change this? How do you decide what percentage to allocate?
Daisy Chaining - This is setting up your networks in a chain so that the top of your chain is your best network and you default impressions from one network to the next. How often do you test networks at different spots in your chain? Do you calculate how much you’re truly earning from your impressions?
