Head over to Amazon and search for some books about your topic. Have a quick look at the Table of Contents section of the books (to give you an idea of what topics were covered), and more importantly, read the reviews that were left by readers. Negative reviews will often reveal the topics that readers were hoping would be covered (or covered in more detail) in the book, but were not.
WordPress boasts of being easy to use for amateurs. However, their support is ludicrously awful--forums only, no backup for more difficult situations. I had an 5 yr plus site that, several dead laptops later--a lost passord & original receipt, pre-2-factor, a free site--that I have lost access to . WP kept repeatedly sending the same canned messages that gave no help at all. I've been at it for WEEKS, & though onechat person offered to send me to customer help, that never happened. I strongly recommend avoiding WordPress.
Yes, you can type “free website hosting” into a search engine of your choice, and you will get results. Don’t do it. At best, you will be stuck with shoddy service, semi-reliable uptime, and ridiculously short-lived storage and bandwidth capacities. The free options out there will frustrate you, and putting yourself through that makes zero sense when you can have quality hosting for as little as $2 a month.
If you want to use a custom domain name (perhaps you already have your own domain) then you will need to purchase one of the premium plans. As a rule, the most basic paid plan for each free web creator will allow you, among other things, to use your custom domain name. In addition, Wix has a separate option – Connect Domain, which allows you to add your custom domain at a price half that of the base premium plan. But at the same time, this option does not remove Wix brand ads.
An uptime guarantee from a web host basically says “We promise that your website will be online __% of the time during this billing cycle.” The best web hosts will set that guarantee as close to 100% as possible, and that’s exactly what you should be looking for. By having this guarantee in place, you’re assured compensation from your host in the case that there is a server outage or something else takes your site down.
