DSP vs ad network
An ad network buys or aggregates inventory, packages it, and resells it at a markup the buyer does not see. A DSP is software the buyer operates to bid on inventory across many sources at auction prices with a disclosed fee. Networks are simpler and less transparent; DSPs require expertise and give control. Google Display Network is the largest network; The Trade Desk and DV360 are the largest DSPs.
| DSP | ad network | |
|---|---|---|
| Who buys | The network, then resells | You, through the platform |
| Price transparency | Low; markup hidden | High; fee disclosed, log-level data available |
| Inventory | Network's own aggregation | Every exchange the DSP connects to |
| Control | Limited | Full: bids, audiences, frequency, brand safety |
| Effort | Low | High; skilled operator needed |
