What kind of orders are available in the 'ClickBank Marketplace' set?

From the 'ClickBank Marketplace' set you can order vendors by: Gravity, Popularity Rank, Avg $/Sale, Initial $/Sale, Avg Rebill Total, Avg %/Sale, Avg %/Rebill, Commission, % Referred. Check what each Clickbank stat means.

As the matter of fact: 'Popularity Rank' is the same way as vendors are ordered by default in the official ClickBank marketplace. This parameter takes into account real net sales of each vendor.
