Web hosting
Web hosting is a service that stores a website's files and data on servers connected to the internet and delivers them to visitors' browsers whenever someone opens the site, around the clock.
Hosting is the place a site lives, not the domain name that points to it and not the website itself. You can buy all three from one company, but they are different things. Hosting ranges from shared hosting, where many small sites share one server, through a VPS with reserved resources, to cloud and managed platforms that scale automatically. The right choice depends on traffic, technology and how much server management you want to do yourself.
Managed hosting means the provider also looks after the software layer, for example keeping WordPress itself updated, handling caching and restoring backups for you. Unmanaged means you get the server and the rest is yours. The labels are used loosely, so read what a plan actually includes: updates, backups, malware scanning and how quickly support answers.
How it works
A hosting provider runs servers in data centres with power, cooling and fast network connections. Your site's files, and usually its database, are stored on one of those servers. When a visitor's browser requests a page, web server software on that machine finds or builds the page and sends it back.
Most plans also include a control panel, email accounts, backups, certificates and a way to upload files. What is included, and how much is managed for you, varies widely between providers and plans.
What happens per request depends on the site. A static page is a finished file the server sends straight back. A dynamic page, such as most WordPress pages, makes the server run code and query a database before anything is sent, which uses far more processor time. The resources that matter are processor, memory, storage speed and the network, and the server's physical location affects how quickly the first byte reaches visitors far away.
Example
A local cleaning company's site has a dozen pages and a contact form. It runs comfortably on an inexpensive shared plan with automatic backups and a free certificate. A growing online shop with seasonal traffic spikes and a large product database would need something with more reserved power and better monitoring.
To check your own hosting, log into the panel and find the plan name, its processor and memory limits, where backups are stored and how far back they go. Then run the home page through Google's PageSpeed Insights: a slow server response time points at the hosting, while large images and scripts point at the site itself.
Why it matters for your business
Hosting affects page speed, uptime and security, all of which affect enquiries and search visibility. Cheap hosting is fine for a small brochure site, but the real cost of a bad host shows up as a slow site, unanswered support tickets during an outage or a hack nobody notices. Before paying for more power, check whether the problem is the host or a heavy site; a slow theme on premium hosting is still slow. Location matters too: a server on the same continent as your customers responds faster, and some sectors have rules about where personal data may be stored, which is worth checking before you choose.
Common mistakes
- Choosing a plan on first-year price without checking the renewal price.
- Assuming the host's backups are enough, without ever testing a restore or keeping a copy elsewhere.
- Paying for a large plan when the site's slowness is caused by heavy images or plugins.
- Keeping the domain, hosting and email in one account that only a former supplier can access.
Questions people ask
How much does web hosting cost?
It varies widely. Shared hosting for a small site is usually a low monthly fee, while managed, VPS and cloud setups cost more depending on resources and support. Compare renewal prices, backup policies and support quality rather than headline offers, which often apply only to the first term.
Can I change my web host later?
Yes. Moving a site to a new host is common. The files and database are copied over, the site is tested on the new server, and the DNS is then pointed to it. Done carefully, visitors see no interruption and the domain stays the same.
Do I need web hosting if I use a website builder?
No separate hosting is needed, because it is already included. Website builders host the site for you as part of the subscription, which is simpler but means you cannot easily move the site elsewhere. With self-managed software such as WordPress, you choose and pay for the hosting separately.
