Affiliate marketing is a blog monetization method in which you place a link to a product or company on your website or a social media platform in an attempt to make an income from followers purchasing the product through your link (this is called an affiliate link). Affiliate marketing can be a great way to make money blogging because if there is a product or company that you enjoy, all you have to do is review the product and hopefully others will be interested in buying it as well.
Oh yeah, I also do all of the above for articles that I write for other blogs. So, if I'm guest posting on a blog, I tend to share it even more than I do my own content. If you guest post on a person's website, you should do the same – the more you share it, the more traffic that person will then get, and the more likely they are to re-share it too.
