The thing about rotate4all is that it's extremely difficult to make a significant amount of money. You earn $0.00032 per referral - that's miniscule! It would take you forever to get to the required $2 to withdraw. I don't think that this site is a very good use of your time, and you should invest your resources in other money-making websites.
However, if you really think you can succeed, you should consider advertising your links, or making eye-catching ads. If you have a good following on social media, for example, you can take advantage of the sheer amount of people who view what you post - then, if you post your link, more people would be exposed to it. Therefore, they are more likely to click on your link and get you that extra $0.000032.
