What is a TDS
A TDS (traffic distribution system) decides where each click on a link goes, based on rules, and records what happened to it.
Postback
A postback is a server-to-server request in which an affiliate network tells your tracker that a click converted, usually with the click ID and payout.
ROI
ROI is profit divided by cost, as a percentage: (revenue − cost) / cost × 100%. It shows how much you earn for each unit you spend on traffic.
Prelanding
A prelanding is a page between the ad and the offer that warms up the visitor, for example with an article, a quiz or a story, before they see the offer.
Split test
A split test sends parts of your traffic to different versions of a page or offer at the same time, so you can compare which one converts better.
Bot traffic
Bot traffic is non-human visits to your links: crawlers, scanners, link previews and scripts. It wastes budget and distorts conversion statistics.
