Glad to hear it! Absolutely, CPA credentials are still extremely valuable—though it definitely takes a time/education investment in order to secure those credentials. Worth it though? I’d say hell yes, if the field interests you. Even the side income you could make by doing taxes for people just a few months out of the year can be lucrative here in the U.S. at least.
I would probably rely mostly on Amazon as an affiliate – talk about products you use while using an affiliate link. You don’t necessarily have to focus your entire content on reviewing products, just mention them in your articles and your experience with them – how they helped you. Amazon is good for obvious reasons – super high conversions and most products already have lots of reviews which is very valuable as an affiliate.
Then once you’ve got your domain name and hosting sorted out, it’s time to pick a CMS, or Content Management System, that will let you update pages, build your blog and integrate with all the other services you need. It’s hard to go wrong with WordPress—the CMS powering close to a quarter of the internet. Keep in mind that eventually as you start growing traffic to your blog, you'll be wise to invest in a managed WordPress hosting plan from a company with great service like Kinsta, where all of the settings are custom-tailored and optimized to work particularly well with WordPress-powered websites.
