Every website lives on a computer somewhere. When someone types your address, their browser asks that computer for your pages, and it sends them back. Web hosting is the service of keeping that computer running, connected and secure, so your site is there whenever someone asks for it.
You could, in theory, host a site from a laptop at home. In practice nobody does, because it would need to stay on, online and protected around the clock. Hosting companies do that at scale and rent you a slice.
An everyday analogy
Think of your website as a shop. The domain name is the street address people use to find it. The hosting is the building itself: the floor space where your stock sits, the electricity, the locks and the landlord who fixes the roof.
Different kinds of hosting are like different kinds of premises. Shared hosting is a stall in a busy market hall. A VPS is your own unit in a shopping center. A dedicated server is a whole building with your name on it. The bigger and more private the space, the more it costs and the more you’re responsible for.
What you actually rent
A hosting plan bundles a few things together:
- Storage for your site’s files, images and database.
- Computing power, meaning a share of a server’s processor and memory, which decides how many visitors your site can handle at once.
- Bandwidth, the data sent to visitors as they load your pages.
- Software and tools: a control panel, one-click WordPress installs, email accounts, backups and a free SSL certificate for https.
- Upkeep and support: security patches, hardware repairs, monitoring and someone to ask when something breaks.
The cheaper the plan, the more of the server you share with others and the more limits apply. The more you pay, the more resources are reserved for you, or the more work the host does on your behalf.
What happens on a visit
Here’s the short version of what happens when someone opens your site. Their browser looks up your domain in DNS, which works like a phone book and returns your server’s address. The browser then asks that server for the page. If your site runs WordPress, the server builds the page from your theme and database and sends it back, along with images and styles.
All of that happens in a moment, and your host is responsible for most of it. That’s why the quality of the server, the software on it and its distance from your visitors all affect how fast your site feels.
Domain vs hosting
These are two separate purchases that people often confuse. A domain is the name, like example.com, which you register yearly through a registrar. Hosting is where the site’s files live. The domain’s DNS settings point visitors to your host.
Many hosts include a free domain for the first year, which is convenient but not required. You can register a domain at one company and host with another; Namecheap, for example, is best known as a domain registrar. Just remember both renew separately.
Types of hosting
Shared hosting
Many websites share one server and its resources. It’s the cheapest option and the right one for most new sites, blogs and small businesses. The host manages everything. The trade-off is that a very busy neighbor can occasionally affect you. See our best shared hosting picks.
VPS hosting
A virtual private server splits one physical machine into isolated sections, each with guaranteed resources. You get more power and control, and usually more responsibility for setup and security unless you pay for a managed plan. See our best VPS hosting list.
Cloud hosting
Your site runs on infrastructure from large cloud providers, and you can usually add resources as you grow, often paying by the hour or month. Managed platforms take care of the technical side for you. See our best cloud hosting picks.
Dedicated servers
A whole physical server for you alone. Maximum performance and control, at the highest price, and most suited to large sites or businesses with specific requirements. See our best dedicated servers list.
Managed WordPress hosting
Hosting tuned specifically for WordPress, with the host handling updates, caching, security and backups. It can run on shared, VPS or cloud servers underneath. See our best WordPress hosting rankings.
What to look for
- Speed: modern server software and caching, and a data center near your visitors.
- Reliability: an uptime guarantee and a track record of keeping it.
- Support: 24/7 help through a channel you’re comfortable with.
- Ease of use: a clear control panel and one-click WordPress.
- Backups and SSL: both should be included.
- Honest pricing: a renewal price you can live with and a money-back window.

How much it costs
Shared hosting is the cheapest, often a few dollars a month on a long introductory term. Managed WordPress and entry-level cloud plans cost more. VPS plans vary widely depending on how much is managed for you, and dedicated servers sit at the top.
One thing to know before you buy: most hosts advertise an introductory price that rises at renewal. Our guide to hosting renewal prices explains what to expect, and our reviews show both prices in each plans table.
If you’re starting your first website, shared or managed WordPress hosting is almost certainly what you need. Move to VPS or cloud once your site outgrows it, not before.
FAQ
Do I need hosting if I use a website builder?
All-in-one builders include hosting in their subscription, so you don’t buy it separately. If you want WordPress with full control over plugins and themes, you need a hosting plan.
Is free web hosting worth it?
Rarely for anything serious. Free hosts tend to limit resources, show ads, or skip backups and support. They’re fine for experiments, but a low-cost paid plan is a far safer home for a real site.
Can I switch hosts later?
Yes. Your domain and content can move to any host, and several offer free migration. Our guide to moving a site with zero downtime shows how.
