If you've taken the time to build an email list, then you should use that opportunity to survey your subscribers. Consider asking them, specifically, what they're most interested. I recently did this and the answers actually surprised me. However, another thing the answers did was allow me to laser-focus my affiliate offers in the right direction. This is invaluable information and it's coming straight from your list.
Recipes: If you use any type of social media, you know that recipes are a great way to create shareable content. If you can find some way to relate your topic to food and include a recipes section, you’ll have a place to add unlimited content. Plus, you can extend your product promotions into related cooking tools. Need a source for blog-worthy recipes? Check out the freelancers at Fiverr.
Very useful info, and thanks for the heads-up about Etsy not allowing affiliate links on Pinterest! Have you ever tried advertising on Pinterest, i.e. paying Pinterest to promote your pins? I was wondering if that could be lucrative with affiliate marketing, where the margins are always lower than when you have your own product to sell. I’m also wondering if it would be lucrative to advertise on Google, Facebook and Youtube (found this guy who supposedly made a lot of money that way – https://moneytestimonials.com/crestani-free-webinar/ ). I’ll probably do my own experiments with this but if you have experience in this area I’d be very interested to hear about it!
