What is web hosting and how does it actually work?
Web hosting stores your website's files on a server, a powerful computer connected to the internet around the clock, and delivers them to anyone who visits your site. Without hosting, your website exists only as files on your own laptop. Nobody else can see it.
When someone types your domain name into a browser, a system called DNS (the internet's address book) points that request to your host's server. The server sends back the pages, images, and code that make up your site.
The hosting company's actual job is keeping that server running, secure, and fast, and giving you the tools to manage your files, email, and databases. That's it. Everything else in a hosting sales pitch is extras.
How much does web hosting cost?
Basic shared hosting (where your site sits on the same server as hundreds of others) typically starts at a few pounds a month for the first term. VPS hosting, cloud hosting, and dedicated servers cost more because you're paying for dedicated resources rather than a slice of a shared one.
The number that matters more than the headline price is the renewal rate. Almost every host discounts the first term heavily, then charges significantly more when you renew. It's the single biggest source of complaints we see from readers who found a host through generic "cheapest hosting" articles.
There are also costs that rarely show up in the advertised price. SSL certificates (which encrypt data between your site and visitors) used to be a paid add-on, but free options through Let's Encrypt have made that less of an issue for most providers now. What still catches people out is backups, staging environments, extra email accounts, and migration fees if you ever want to leave.
- Renewal price increases, often two to four times the introductory rate
- Paid backups or backup restoration fees
- Charges for extra storage, bandwidth, or website count once you scale
- Migration fees if you cancel and try to move your site elsewhere
Before you buy, check the renewal price on the provider's own site, not just the checkout page. If a host hides that number, take it as a warning sign.
What are the different types of web hosting?
The main types are shared hosting, VPS hosting, cloud hosting, dedicated servers, and managed WordPress hosting. Each one trades cost against control, performance, and how much technical work falls on you.
Shared hosting is the cheapest and easiest starting point, but performance can dip if other sites on the same server get busy. A VPS (a virtual private server) gives you your own slice of resources on a shared machine, so you get more consistent performance without the cost of a full dedicated server.
Cloud hosting spreads your site across multiple servers, so it handles traffic spikes better than a single fixed server can. Dedicated hosting gives you an entire physical server to yourself, which is overkill for most small sites but necessary for high traffic or strict compliance needs.
- Shared hosting: cheapest, fine for small sites and beginners
- VPS hosting: dedicated resources, more control, needs some technical comfort
- Cloud hosting: scalable, handles traffic spikes well, pricing can vary with usage
- Dedicated hosting: full server to yourself, best for large or sensitive workloads
- Managed WordPress hosting: shared or VPS infrastructure tuned specifically for WordPress sites
You can compare all these categories in detail on our best hosting pages, which break down providers by exactly this criteria.
How do I choose the right hosting for my website?
Choose based on your expected traffic, your technical comfort level, and how much growth you're planning for, not whichever host has the biggest discount banner. A small portfolio site and a growing ecommerce store have completely different needs, even if they're the same price today.
I've watched clients spend months building a store on hosting meant for a personal blog, then panic when a traffic spike from a marketing campaign took the whole site down. The hosting was never the problem until it suddenly was, at the worst possible moment.
Be honest about how much server management you actually want to do. If you don't want to touch a command line, managed hosting is worth the extra cost. If you're comfortable with basic server admin, a VPS gives you more control for less money over time.
Our hosting match tool asks about your traffic, budget, and technical skill, then filters our directory of over 28,000 providers to the ones that actually fit. It's a faster starting point than scrolling ten "top 10" articles that all recommend the same three affiliate partners.
What's the difference between hosting and a domain name?
A domain name is your website's address, like an entry in a phone book. Hosting is the actual space where your website's files live. You need both, and they're usually bought separately, though many hosts bundle a free domain into the first year of a hosting plan.
Think of it as renting land (hosting) and registering a street address (domain) that points to that land. You can move your domain to point at different hosting at any time, and you can host multiple domains on one hosting account.
Never let a host lock your domain registration into the same account as your hosting without checking the terms. If you ever want to switch hosts, having your domain registered separately makes the move far simpler.
Do I need managed WordPress hosting or is shared hosting fine?
Basic shared hosting is fine for a low-traffic WordPress site that doesn't need much beyond the basics. Managed WordPress hosting earns its extra cost once your site grows, needs faster load times, or you want someone else handling updates and security.
WordPress runs a huge share of the websites on the internet, and usage data from WordPress.org shows just how dominant it remains as a platform. That popularity is exactly why it's also the most targeted platform for attacks, which is where managed hosting earns its keep.
Managed WordPress plans typically include automatic updates, built-in caching, and staging environments to test changes safely before they go live. Generic shared hosting usually leaves all of that to you.
If you're running WordPress and unsure which category fits, our WordPress hosting rankings compare providers specifically on the features that matter for that platform, not generic shared hosting metrics.
What should I look for in a hosting provider's uptime and support?
Look for consistently strong uptime (the percentage of time a server stays online and reachable) and support that actually solves problems rather than just responding quickly. A fast reply that fixes nothing wastes your time twice.
Marketing pages love to quote impressive uptime numbers, but they're self-reported and rarely independently verified. What matters is how a host performs over months, not what a landing page claims on day one.
This is exactly why we built the HRI score, an algorithmic ranking that pulls in real performance and reliability signals rather than paid placements. You can browse the full hosting rankings to see how providers stack up against each other on objective measures instead of marketing copy.
When you test support before committing, ask a specific technical question rather than a generic one. How a host answers a real problem tells you far more than how fast they reply to "do you offer hosting."
How do I migrate to a new host without losing my site?
Back up your entire site, including the database, before you touch anything. Then set up your new hosting account, upload everything, and test the site fully on a temporary URL before pointing your domain at it.
DNS changes (updating where your domain points) can take anywhere from minutes to around 48 hours to fully propagate across the internet. During that window, some visitors may briefly see the old site and others the new one, so avoid making further changes until it settles.
Don't cancel your old hosting account the moment you switch. Keep it active for a week or two after migration in case something breaks and you need to revert quickly while you troubleshoot.
If your new host offers a free migration service, use it, especially for anything running a database like WordPress or WooCommerce. It's usually far less error-prone than doing it manually yourself.
Three things to do right now: check the renewal price of any host before you buy, not just the introductory offer; use our match tool to filter our directory of 28,000+ providers by your actual traffic and budget rather than picking from a generic top ten list; and if you're running WordPress, start with our dedicated WordPress hosting comparison rather than a general shared hosting plan.
Frequently Asked Questions
Is cheap web hosting worth it?
Cheap hosting is fine for a low-traffic personal site or a project you're testing out. It becomes a problem once your site grows, gets real traffic, or needs reliable uptime, since budget shared plans often struggle under pressure and offer limited support.
How much should I budget for web hosting a small business site?
Budget for the renewal price, not the introductory offer, since that's what you'll pay long term. Factor in a domain, SSL (usually free now), and possibly a small monthly cost for backups or email if your plan doesn't include them.
Can I switch hosting providers later?
Yes, and it's common practice. Keep your domain registration separate from your hosting account so switching is straightforward, back up your site fully before moving, and use a migration window where both old and new hosting stay active briefly.
Do I need a dedicated server for a small website?
No. Dedicated servers make sense for high-traffic sites, strict compliance needs, or specific performance requirements. Most small and medium sites run perfectly well on shared hosting, a VPS, or managed cloud hosting at a fraction of the cost.
What's the real difference between shared hosting and a VPS?
Shared hosting puts your site on a server alongside many others, sharing resources. A VPS gives you a dedicated slice of a server's resources, so your site's performance isn't affected by what other sites on the same machine are doing.
