What geographies does Demand Hub support?

If your website receives a significant amount of traffic from countries outside of the US, Canada, France, UK, Germany, and Spain, it's highly likely that Demand Hub may under-perform in those geographies. This is primarily due to lower demand in these regions, as well as lower server response times and win rates.

To optimize the performance of Demand Hub, it is recommended to filter out ad requests from those geographies.

This can be done by using geotargeting or IP address blocking to limit ad requests from countries outside the recommended geographies. 

By doing so, you can ensure that Demand Hub is used most effectively and that you are maximizing your inventory ECPM.
