There are two kinds of WordPress sites, and depending which kind you have, your features (and ability to do certain things) will differ.
The most obvious way to determine which version you have (if you don’t already know) is to login and then look at the interface for your pages. (See image above.) But if you’ve connected your self-hosted site to WordPress.com (in order to use JetPack or some other plugin), then the interface may be misleading. At the end of the day, you should know if you’re paying for hosting somewhere or not.
WordPress.org (aka Self-Hosted)
The bulk of the GoCreate.me website is aimed at authors with self-hosted WordPress (.org) websites. In order to make use of the free files downloadable from WordPress.org, you need to pay for hosting services somewhere.
GoDaddy, BlueHost, and several other popular companies offer cheap, shared hosting, but you normally get what you pay for. Such companies may work at the beginning, but once you start getting real traffic, you will likely need to upgrade. If you need hosting but don’t know which company to go with, you can read more about the companies I use, love, and recommend here.)
Advantages of WordPress.org
You can upload any theme and plugin. No limitations! This means that all themes discussed on this website would work for you.
Disadvantages of WordPress. org
You have to pay for hosting + domain name.
You must keep your WordPress installation (along with all of its plugins and themes) up-to-date to reduce the risks of getting hacked. You are also in charge of your own backups (unless your hosting company takes care of those for you).
See my recommended services page for one amazing hosting company that keeps WordPress up-to-date, does daily backups, includes a free security certificate (SSL), and takes care of beefing up security at the server level so you don’t have to install (and constantly update) security plugins. They even include a staging version of your site so you can play with things without worrying about breaking your live site.
Technically speaking, you could set up a free website at WordPress.com. But, if you want to run your author business like the business that it is, you’ll have to upgrade to their paid plans to get rid of ads, get your own domain name, and install certain plugins and themes that are not included. So, if you want to upload any of the (free or paid) themes discussed on this site, you’ll have to upgrade to the business plan, which isn’t cheap. As of September 2018, the business plan costs $25 USD/month when billed annually, which is comparable to good quality hosting and more than most shared-server hosting companies would charge, BUT WordPress.com takes care of keeping your site secure, backed up, and up-to-date, which not all hosting companies do.
Advantages of WordPress.com
The free version is completely free. If you’re not sure whether WordPress’s interface would work for you, give it a shot. But if you’re serious about your author website, you’ll likely have to upgrade.
The WordPress files are kept up-to-date by the developers, so you don’t need to worry about updating those.
Disadvantages of WordPress.com
You have to pay to upgrade your plan if you want to do the things your author website needs to do, like get your own domain name and remove ads. Similarly, you’ll really struggle to find a theme offered by WordPress.com that works perfectly for your author needs. But if you upgrade to the business plan, you could upload your own (or GoCreate.me’s) themes and associated plugins.
You can’t upload files via FTP (File Transfer Protocol) and you’re stuck with WordPress.com’s limited interface. There’s no cPanel or hosting interface that will let you do the things self-hosted WordPress owners can do.

Which is best?
If you’re technically minded, are willing to get your hands dirty, and want to control EVERYTHING that appears on your site, I’d recommend the self-hosted version. With the tutorials I provide here, you will be able to create a beautiful author website, and you’ll know how to keep everything up-to-date and backed up. If you’re technically inclined, the WordPress.org interface and the ability to upload your own files via FTP makes everything easier.
If you get a headache just thinking about having to login to your site at least monthly to updates your plugins, then go with WordPress.com. (Or consider other alternatives such as SquareSpace or WIX, but keep in mind that you won’t be able to control every little detail about the appearance and/or functionality of such sites.)
The information above is just the tip of the iceberg.
