If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources. As long as the blog is setup the right way, in the right niche, with the right content targeted at the right audience, and the offer is complementary to the content, you could make a tremendous amount of passive income from a blog.
A website called AchieveMint gives you points for engaging in healthy activities, like exercise, tracking your eating habits, or even taking health related surveys. Points can be redeemed either for cash (10,000 points are worth $10) or for Amazon Gift Cards. The app actually connects with other health apps, like Fitbit and MyFitnessPal, to track your progress.
Freelancing has always been a popular way to earn money online and the Internet has a plethora of options. There are several websites offering freelance tasks for people with varying skills. All you need to do is to create your account, browse through the listings, and apply for the task that suits you. Some websites may even require you to create a personal listing with the details of your skillset, so that interested clients can contact you directly. Outfiverr.com, upwork.com, freelancer.com, and worknhire.com are some websites that provide freelance jobs. You can earn anywhere between $5 and $100 through these websites.
How much will you make? I think my best month with Google AdSense was almost $5,000 over the last ten years. That amazing month blew my mind since it was actually near the beginning of my blogging journey. When you go from making zero to $5,000 in a month, that will rock your world. For me, it also got me even more excited because I knew there were other ways to monetize.
