If you already have a blog, a good way to know if your niche works for affiliate marketing is to check if there are products or services related to your topic that people are buying. You can search for affiliate programs or online stores that offer items connected to your content. Also, see if other blogs in the same niche are using affiliate links. That’s usually a sign that money can be made in that space. Another thing to check is how many people visit your blog and what posts get the most attention. If readers are interested and there are things to promote, it could be a strong niche. Has anyone here tested their blog this way?
