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.
While I’m not positive that you can make serious money by taking surveys (I never made a ton of money), it’s very easy to get started and earn a little extra money in your spare time. When you’re on the computer surfing the web, all you have to do it take a few minutes out of your day to give your honest opinion about a wide variety of topics and products.
I've got a $185,000 CD generating 3% interest coming due. Although the return is low, it's guaranteed. The CD gave me the confidence to invest more aggressively in risk over the years. My online interest income has come down since I aggressively deployed some capital at the beginning of the year and again during the February market correction.

Look into survey sites like MyPoints, Survey Junkie or Vindale Research where you’ll get paid just for taking surveys and giving your opinion. Sounds like a pretty sweet deal, right? Just remember, these sites are looking for specific criteria. So you might have to wait for the right survey to come along that you qualify for. Plus, you’ll have to reach a certain threshold before you can cash out your points. It’s not a get-rich-quick opportunity by any means, but that extra cash can still add up over time. If you’re the patient and persistent type, give it a shot!
This has become a popular business model for online entrepreneurs over the past several years, and will probably just continue to grow in popularity. The best thing about selling online courses is that once you do the up-front work in creating the course and setting up your marketing strategy, you can get paid over and over again for work you do once.
