Overall Satisfaction

Open X is being used in the form of buying the inventory through our DSP partners in a RTB dynamic CPM buy. Anyone managing campaigns would have experience with Open X inventory and buying from the exchange.


  • When it comes to RTB and spending on the open exchange market, the number one reason why we spend in one exchange over another is simple performance
  • When Open X doesn't perform which it tends not to, we have to shut that exchange off. This exchange tends to not perform at a CPA or CPC KPI and tends to not have the safest sites either.
  • Because I only use Open X as an exchange which I tap into from a DSP I can't speak to it's other capabilities.


  • Get better publishers, have more transparency.
If OpenX wants to be used or adopted by more desks or RTB partners than it needs to provide the transparency and premium inventory that a AppNexus, ADX and Rubicon provide. This goes for the open exchange and private marketplaces.
Once you see an exchange not perform over a long period of time you start to assume that it will never perform well.
Again, because I'm only speaking to the exchange itself, I can say that its all about performance on the initial weeks of a campaign. When we pull reports and see that OpenX doesn't perform compared to other exchanges we exclude it from the campaigns.
