Rev Share - Simply share the profit/revenue (depending on business) between advertiser and publisher.
CPS/PPS - Cost per Sale/Pay Per Sale - Pays on the publisher one time for sending a purchase to the advertiser.
CPL/PPL - Cost Per Lead/Pay Per Lead - Pays the publisher one time for sending one lead to the advertiser.
CPC/PPC - Cost Per Click/Pay Per Click - Pays the publisher once for sending one click to the advertiser.
CPM - Cost per thousand impressions (or clicks in bulk traffic) - Pays per 1000 impressions of an ad.
CPV/PPV - Cost per View/Pay Per View - Pays the publisher for every time they show the advertisers ad.
CPI/PPD - Cost per Install/Pay Per Download - Pays the publisher for every person they send to download something from the advertiser.
CPA - Cost per Action - Which encompasses all of this as well as other things that are more complex like "per user register, complete questionnaire, stay on site 5 minutes browsing". Technically doesn't include revshare as its not a "pay per" model. CPL is CPA but CPA isn't necessarily CPL but it could be.
Hope somebody learned something.
