5BillionSales is a program that promises to pay you for the data generated in the form of browsing as you are on your web browser using Google/Bing search engine. You need to download their extension and use the extension while working on your device (desktop/laptop/tab/smartphone). You can signup through our link here.
Also, they have an affiliate program in which you are rewarded for the signups and activities generated from your affiliate link.
This is a closed program, meaning that you need a referral to sign up.

This is apparently a new program and apply your own discretion before joining or the level of commitment you are going to put. My advise is to never rely on one source of income.
