To maintain secure WordPress hosting, it’s important to keep your WP software version up to date, install and update plugins with caution, and use some form of site encryption service. Some hosts will include basic SSL certificates in certain plans, or you can sign up for the level of security you’d like with services like Symantec or The SSL Store.
Before you sign up for a WordPress web hosting service, you should look for these attractive—and possibly essential—features. Ideally, you'll want to invest in a WordPress host that provides unlimited monthly data transfers, email, storage, and 24/7 support. Many WordPress web hosts that place caps on those features, particularly on the managed side of things. WP Engine ($35.00 - 20% Off with Promo Code PCMAG20 at WP Engine) , for example, limits sites to 400,000 visitors and a relatively paltry 30GB of storage. If you expect lots of site growth, you'll want a host that can properly accommodate your website's future expansion.
You could think of the sites that share your server as your roommates; there's really not that much separating you from them. Sure, you can close the bedroom door, but they can still cause nightmares for you in the kitchen and the bathroom. In web hosting terms, all the sites share a single server's resources, so huge traffic spike on Site A may impact the neighboring sites' performances. It's even possible that another site could take down the shared server altogether, if it crashed hard enough.
Note that we're speaking here of the WordPress.org CMS that acts as the foundation for your self-hosted website, not WordPress.com. The latter CMS has more in common with website builders than traditional website hosting. In effect, WordPress.com is a turnkey (and more limited) WordPress solution, whereas the services in this roundup offer a vastly more flexible (and labor-intensive) DIY approach.
There are free web hosting available, but almost all of them have some sort of catch. Usually, you can find free WordPress hosting being offered in online forums or small groups. In most cases, these are managed by an individual who is reselling a small part of his server space to cover up some revenue. Often the catch is that you have to put their banner ads on the site. Some may ask you to put a text link in the footer of your site. These folks will sell that banner ad or text link to cover up the cost of your free space along with pocketing the profits. The biggest downside of having a free host aside from the ads is that they are unreliable. You never know when this person will stop offering the free service. They can leave you hanging at any time. If you are serious about your website or business, then avoid Free WordPress hosting at all costs.
A handful of domains will have restrictions on them, which means you can only purchase them if you meet or exceed certain criteria or have authorization (some examples are .gov, .edu and .mil). But most extensions are available to everyone. In fact, most country code Top Level Domains (ccTLDs) are available for anyone to purchase, even if you don't reside in the country code in question.
