UserTesting is one of the best platforms to make money easily and effectively. Their customer support is unbelievable and they are constantly posting tests and getting better and better. Some survey unmoderated tests even gives bonus payments and if someone qualifies for moderated tests 30$ and 60$ and sometimes even 90$ could be earned. I've given both moderated and unmoderated test and they teach you via lessons so that you don't have to be pointless about what you are doing. Up until now UserTesting is the best website/app testing platform on all of the web.
