In short, yes, you can monetize it. Bloggers make a majority of their money from affiliate marketing, which is basically referring a product or service through your blog. You will be assigned a specific link to the product that you're blogging about, say Redbull. Once a reader clicks on that link and purchases the Redbull, you would get a % of the sale.

OR if you already have a good online following, (1000s of followers) you could negotiate being paid to blog about certain products. For example, say you took the supplement L-Carnitine while on your weight loss journey and noticed great results. You could include the brand of L-Carnitine you took for a pre-negotiated fee with the company, or exclude the company and just talk about the nutritional supplement.

I'd love to hop on a call and talk about how we can give this online journey some traction, or just answer some general questions you have. Regardless of your decision, I hope this helped. Good luck! :)
