We want you to get the best results from your campaigns. To do so, the platform allows you two levels of source optimisation:
Macro-level – Feed
Micro-level – Zone limitation
By listing feed or zone IDs which you want to include or exclude from your campaign in the respective fields, you can set yourself a custom whitelist and/or blacklist of sources you will be getting traffic from.
Whitelist — means that you will ONLY be getting traffic from the listed sources.
Blacklist — means that you will be getting traffic from all the sources, except the ones listed.
