The basis of rewards for website operators is called Proof of Online, which is a number that quantifies how many minutes the users spend on each website.
The webserver will store each websites stats. Every week each websites visits will be converted to ICE tokens after a period of 7 days (visits for 17 of the month will be paid on the 14th, etc.). Furthermore, ICE tokens can be converted into real money through exchanges or they can be used for microtransactions and other daily uses on the platform.
