Straight answer first

In a line: teach browsers to keep your assets, so repeat visits load almost instantly — a intermediate-level task that takes 15 minutes.

The walkthrough below covers every step, the mistake most people make, and the shortcut worth keeping. On Hosting Seller plans several of these steps are already done for you, and we say where.

On our own kit

You do not need to be technical for this. The walkthrough is written for first-timers, tested on our own platform, and honest about which parts are genuinely fiddly and which are merely unfamiliar.

One promise before you start: nothing in this guide is irreversible. Where a step could bite, we say so and give you the undo.

The overview before the detail

The job breaks into a few clear stages: know what the headers do, switch it on in the cache plugin, or write the headers yourself, solve the update problem and check the network tab.

No stage needs code or a terminal unless the guide says so outright, and where it does, the exact commands are printed. The full step-by-step sits below; the sections around it give the context that makes it stick.

Where this goes wrong, and how not to

Caching HTML pages in the browser for hours. Content updates then take hours to reach returning readers. HTML stays short-lived or uncached while its assets cache for a long time, which is exactly the split the defaults already implement.

Forewarned really is forearmed here. This one mistake accounts for most of the frustration the subject produces, and it is entirely avoidable once somebody names it.

The shortcut, straight from the support desk

Fonts are the forgotten win. They change roughly never and load on every page, so a year-long cache header on the font files removes them from every repeat visit for good.

It costs a minute now and pays that back every time the job comes round again — which, like most hosting jobs, it certainly will.

How our platform shortens this

Several steps in this guide exist only because hosting historically made you do them. On our plans SSL issues itself, backups run daily without being asked, and one-click installers replace the manual setup entirely. What is left is the part that is genuinely yours.

Stuck halfway through at an odd hour? That is exactly what round-the-clock human support is for — tell us where you are in this guide and we will pick it up from there.

A good platform makes every guide shorter

Every walkthrough on our how-to shelf is tested on the platform we actually run — cPanel, LiteSpeed, NVMe, one-click installs — so the instructions match your screen instead of gesturing vaguely at it.

Bring an existing site and we shift it across at no charge — usually inside 24 hours, with nothing going dark while we work.

Why Hosting Seller

On every plan, as standard

Automation where it belongs

SSL, backups and installs run themselves here, so the guide covers only what is genuinely yours to do.

Help on the counter

Stuck on step three at midnight? Support answers at any hour, mid-guide included.

Works exactly as written

Every step tested on the platform we run — no 'your host may differ' hand-waving anywhere.

The undo is always named

Where a step could bite, the guide says so and tells you how to put it back again.

The snag, named early

The classic mistake for this exact job is flagged before step one, so 15 minutes stays 15 minutes.

5 steps, no filler

Each stage is a few minutes of steady clicking, with the fiddly parts marked as fiddly.

First Steps

From choosing to live

1
Know what the headers do
Cache-control headers tell a browser how long to keep each asset. A returning visitor's browser skips re-downloading anything still fresh, so the second load happens locally.
2
Switch it on in the cache plugin
LiteSpeed Cache's browser-cache setting writes the headers for you. That is the hands-off route, and it covers the standard asset types sensibly.
3
Or write the headers yourself
Expires and Cache-Control blocks per file type: long lifetimes for images and fonts, shorter for CSS and JavaScript, none at all for HTML.
4
Solve the update problem
Long-cached assets need cache-busting when they change. Versioned filenames or query strings, automatic in WordPress asset pipelines, let 'cache for a year' live beside 'update today'.
5
Check the network tab
On a repeat visit, requests should come back as from-cache or as 304 responses. The dev tools network panel is the receipt that says your headers landed.

The questions we get asked most

How is this different from server caching?

Server caching speeds up the first visit by having the response pre-built. Browser caching removes the transfer altogether on repeat visits, because the assets are already on the visitor's machine. The two compound, and fast sites use both.

I changed the CSS and visitors still see the old design.

Their browsers are honouring the lifetime you set. Cache-busting — a changed filename or a version string — forces a refetch. A hard refresh only fixes your own view; versioning fixes it for everybody at once.

What if the site outgrows the plan I bought?

You move up in place. Plan changes are made from the client area with no migration and no downtime, and the range runs from small shared accounts through VPS to whole dedicated servers. Growing becomes a line change on your account rather than a hunt for a new host.

How do I read the mail when I am away from the desk?

Webmail opens in any browser, and every mailbox also speaks IMAP, POP and SMTP — so the mail app on your phone, the client on your desktop and webmail all show the same messages in the same order.

What happens to my files if I leave?

The site and the files stay yours. Pull a full backup from the panel whenever you like, before or during cancellation. Domains remain registered in your name for the term you paid for and can move to any registrar once the standard 60-day window has passed.

Who actually runs the company?

Hosting Seller is a trading name of Bohzo Ltd, a company registered in England and Wales — a real business with a public record and terms published under English law. Looking that up is worth doing about any host before you hand over your domain.

Is the SSL certificate genuinely free?

On every plan, with nothing held back. The certificate is issued the moment your domain points here and reissues itself well before expiry. The encryption is the same as a paid DV certificate — paid tiers exist only for wildcard coverage or organisation validation, which most sites never need.

Packing up and moving host? Take our checklist.

A plain running order for a move nobody notices: what to copy first, how to carry email across without dropping a single message, when to point DNS, and the two slips behind nearly every hour of downtime we get called about.

Your site is worth better hosting.

From a first website to a rack of servers, moving up is a change to your account rather than a migration.
