How it works

AdSelect collects the following information:

• Campaigns (start and end time, filters)
• Banners (banner sizes, keywords, publisher)
• Payments for events (keywords, paid amount)

“Value” of banners is determined based on keywords. Each keyword has an average payment value determined by past payments.

Note

[var] in the following documentation means a configurable variable. It can be different for each step.
