As the name suggests, WordPress hosting is web hosting that has been optimized for the needs of a WordPress website. It’s important to understand that this isn’t a type of plan in the same way that shared hosting is. WordPress hosting can be shared, dedicated, or something else entirely.
What matters is that WordPress hosting better meets the performance and security needs of sites built using the platform. You may also get access to platform-specific features such as pre-installed sites, automatic WordPress updates, and dedicated WordPress support.
The details of your plan will depend on the provider you choose, of course. In addition, many hosts also offer both managed and unmanaged WordPress hosting plans. Unmanaged plans leave site optimization and server management up to you. A managed plan is slightly more expensive, but provides you with a lot more help keeping your site running smoothly.
