WordPress.org references the open-source (free) software that can be downloaded and installed pretty easily, particularly if you have a web host that makes this process a breeze. Self-hosted WordPress allows you to capitalize on the robust offerings of the established content management system, plus the potential for more features, such as a free domain, unlimited email accounts, marketing credits, and expert support).
If you're planning to create a WordPress-powered site, there's no reason not to invest in WordPress-specific hosting. It's chock full of benefits. That said, a WordPress environment won't allow you to set up a non-WordPress site—that's something else to keep in mind, especially if you have a site in mind that will rely on specific frameworks, for example. In such instances, you'll want to go build your site on shared hosting, VPS hosting, or dedicated hosting services. And, if you want to start your own web hosting company, reseller hosting is the way to go.
The article doesn’t list geographical location of the server as one of the consideration one should consider when choosing a hosting company. Isn’t geographical proximity, between the hosting server and the targeted population of the website, one of the parameters that Google’s algorithm uses when ranking a website? E.g. If I my website is in German and is targeting German people, wouldn’t it be better to host it in a server in Germany (ignoring, for the sake of this question, the issue of speed)?
A subcategory of reseller is a web operative who will buy a large amount of hosting space from an Internet service provider (ISP) and then resell some of this space to clients. Their hosting is often managed through a virtual private server (VPS) which allows them, through a control panel, to administer bandwidth, databases, passwords etc., for the client.
