Attention residents of the UK, Canada, and Australia: Google would like to ask you some questions. In exchange you will be paid exactly one pittance. Don't complain or they'll cut it to, like, 0.75 of a pittance. But hey, free money is free money. All you have to do is grab the newly updated Google Opinion Rewards app and wait patiently for Google to call your number.
This app launched in the US a few months back, offering Google Play credit in exchange for answering survey questions. The payout was fairly substantial early on, but has since dropped off. Once installed, Google Opinion Rewards will notify you when there is a survey waiting. Most of them are 1-3 questions and pay the equivalent $0.25-0.50.
Maybe with the expansion of Opinion Rewards to other regions there will be a corresponding uptick in payouts. The only way to find out is to download the app.
