So, how does monetization work through this model? Essentially, publishers or individuals can apply for affiliate programs, wherever they’re available, in order to be added as an official affiliate. Once you’re accepted (or simply approved), you’ll receive a way to share an affiliate link to the product or service you’re interested in promoting. 
If you know your way around booking software, such as Quickbooks, you can pick up work doing bookkeeping for small businesses. This is often very part-time work, a few hours per week, so depending on how much time you have, you could choose to take on several clients.

You don't officially have to be a techie to join, but it definitely helps to be technically-minded. This is a lot more involved than scanning receipts or taking photos, but on the upside, we've heard of people earning £100s/month. We're talking a few hours' work per project, but you're paid accordingly.
Niche-to-win applies here, too. Since you don’t have a masthead of 50 writers, you won’t outcompete with professional publications like Wirecutter as a general review site. You may, however, be able to write, rank, and differentiate yourself by covering all things terrariums or high-intensity interval training. Point being, it’s typically easier to land (pick a distinct niche) and expand (grow into new areas) than it is to compete with a general interest site, especially when you’re getting started.
