How does the bidding system work?
When launched on a new ad zone, a banner will be marked as “new” and needs to run through 10,000 views before being assigned a display chance. Display chance represents the chance that this banner has of being displayed on this ad zone. For example: display chance of 25% means that this banner will be displayed approximately 25 times out of every 100 banner views on this ad zone, with approximately 75 views out of every 100 allocated to all other banners currently running on this ad zone. Banners in each ad zone are ranked in real time according to their eCPM. eCPM = Click-Through Rate * Cost Per Click Bid. Banner with the highest eCPM will have the highest display chance, followed by the banner with next highest eCPM, etc, with lowest eCPM banner having the lowest display chance. Display chance is therefore relative to other ads currently in rotation on a specific ad zone, and may fluctuate according to “market forces”. To increase your banner’s display chance you can increase its CPC
