I come from a quite unsuccessful background of web design/SEO. I blogged because I knew it was good for SEO, but my articles never had a purpose regarding monetization. I finally took a leap of faith and dropped my clients to figure out blogging/affiliate marketing. I was good at website speed optimization and knew hosting was the #1 factor. Looking for the best, I saw SiteGround was rated #1 in multiple Facebook polls and had a great reputation with generous affiliate commissions. So I wrote detailed tutorials on website speed… how to configure WordPress cache plugins, hosting reviews, and other speed-related topics. Usually near the end of a post I would say “Oh, and here’s why you should switch to SiteGround” with evidence on why they’re the best… Facebook polls, Tweets, load time improvements, etc. That’s when things got good. I’ve been broke my whole life and it’s my calling to show people how do this.
For example, if I talk about how cool a product is, and then you find out that I’m an affiliate for them, wouldn’t you as a conscientious observer become skeptical as to whether my information is biased, if perhaps I’m only saying how cool something is because I can get paid for it? Wouldn’t that make you question my integrity with other things I say as well?
