I always add an HTML table of contents to posts to make sure they are long and structured. This has been a HUGE help for me (and my readers) and there are tons of benefits: better chance of getting “jump to links” in Google (see below), increased average time on page, decreased bounce rates, and it makes it easier for readers to navigate through your content.
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.
