To get started as a game tester, sign up with a reputable network such as Keywords Studio, whose Global Beta Test Network (GBTN) helps game developers push their products to the limit and ensure they go to market with as few bugs as possible. GBTN’s tests typically involve dozens to hundreds of testers around the world running simultaneous tests on different aspects of clients’ games. Most tests are time-limited, project-based affairs. Pay varies but typically ranges from $20 to $50 per hour. Diligent, skilled testers who work part-time can earn $10,000 to $20,000 per year; testers who work at or near full time can easily exceed $50,000 per year.
Considering that you have a finite amount of time, passive income should make up a large part of your work. If you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why? Wouldn't you prefer to do the work one time and get paid repeatedly as opposed to relying on your time to generate that income? Invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop.
