It works essentially the same way as the phone apps do above. If you don’t care to let Google know what you do on a daily basis, you can make money from home by letting them monitor your Internet usage. They use the information they gather to help them market/increase the functionality of their advertising programs when targeting users that are similar to you.
A reliable high-speed Internet connect is a requirement, of course, to access the databases from which you’ll work. Often working as part of a team, data entry professionals may be asked to log into a company’s database system to make entries or access data for other purposes. Depending on the employer and industry, a high school degree, and perhaps an additional certification, may be the minimum education requirements. And of course you’ll need to be fast and highly accurate at inputing data.
If you’re willing to take on some risk and have the heart of a true hustler, you can make extra money online doing commission-only sales for startups and other businesses. While you won’t be getting a regular salary, with the right sales strategies and skills as an inside sales rep, you can make decent money for each sale you bring in. And because you’ll most likely be working with startups, if you can negotiate a little equity you could profit big time if you're pitching a solid product and the startup succeeds.
