There is enough material available online to help create your own website. This includes choosing the domain, templates, and the design for your website. Once ready to service the visitors with the relevant content, sign up for Google Adsense, which when appear on your website and clicked by visitors help you make money. The more the traffic you get on your website, the more will be the potential for higher earnings.
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.
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.
