There are a few ways to monetize a nutrition blog. The most common way is to sell advertising space. This can be done through Google Adsense, which allows you to insert ads on your website and earn money based on the traffic they bring in. You can also sell affiliate products, which are products that you recommend to your readers and earn a commission if they purchase them.
You can also sell eBooks, subscriptions, or consulting services. The most important thing to remember is to be authentic and credible with your readers, and focus on providing valuable information that will help them improve their health. If you do this, you should have no problem monetizing your blog.
