Shopify is another great option if you are wanting to create your own eCommerce store. Shopify is arguably easier to set up than WooCommerce but will give you less control over your storefront and cost you more long term.

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.
