2. Of course, nearly all my readers are using WP so I’m biased. But even so, most successful affiliates use WordPress. There are less restrictions in terms of hosting (site speed), design customizations, plugins, cloaking affiliate links, lots of things. I would setup a free wordpress.com site just so you can play with the dashboard and see how you like it. Who knows, you might find a theme you really like (eg. StudioPress) and want to make the transition. I would at least test it out…it’s better to make the transition earlier than later.
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.
