The easiest way to start a blog with a custom domain is through Blogger from Google. The other option is to go to Google Domains directly. After you register a domain you have options to deploy it to Blogger, Google Sites and others. You only pay for the domain name. The hosting and traffic are free. Blogger has been online since 1999 btw. It isn't going anywhere and I say this with confidence. My confidence comes from me personally looking for Blogger blogs and finding old ones (from 1999) that are still updated today. Google would not dare take those peoples medium, it would be an outrage. Some of them get tens of comments on each post. There are also some huge Blogger blogs, for example like this one: https://www.surrenderat20.net/ https://www.surrenderat20.net/ that has thousands of comments on each post. Imagine how much traffic that blog pulls. It is true Google has over the years stripped Blogger of some functionalities but it is still the most flexible Blogging platform. Why? Because you can add custom HTML, Javascript and CSS to each and every individual post/page or site-wide, category-wide etc (try doing that for free on wordpress dot com). They also allow adult content if you can believe it. Their content policy is quite lax.
