The good news is that replacing it is far less work than building the first one. You already know what you sell and what it costs, and your existing pages can be read in as a starting point rather than typed out again.
Six signs it is time for a new website
The menu misbehaves on a phone. The opening hours are last year's. The price list is a PDF. Contact means a form that goes to an address nobody checks. You cannot change a word without asking someone. And nothing on the site can take a booking.
If three of those are true, the site is costing you more than it saves. A driving school whose site still shows last winter's rates is not being frugal; it is quietly turning learners away.
How the change actually happens
You paste the address of your current site or describe the business in a couple of sentences. The new pages are written out for you: a service menu with prices, opening hours, an FAQ and booking.
Then you go through it. Anything you disagree with has a pencil next to it, so you fix the tone, correct a price, remove a service you stopped offering. When it reads right, you publish. Often that happens the same day.
Your old content is not wasted
Text you spent an evening writing three years ago is still your text. It comes across as a starting point, so a dog groomer keeps the breed notes and the honest paragraph about nervous dogs and only rewrites what has actually changed.
What does not come across is the old structure, which is usually the thing that was holding you back. Each service ends up on its own page with its own heading, which is what search engines can work with.
The new one is looked after for you
Part of what makes a site feel old is nobody maintaining it. Managed hosting is in every plan: we run the servers, apply updates and close security holes, and you install nothing at all.
HTTPS certificates are issued and renewed automatically, so the padlock does not lapse on a Saturday. Backups run nightly and the restore is tested nightly, which is how you know the copies would actually open. There are no plugins to age.
When you do not need a new website
If your current site loads quickly, reads well on a phone, shows correct prices and lets people book, keep it. Replacing a working site because it looks a bit dated is spending money on a feeling.
And if the only thing missing is booking, ask your current provider what that would cost first. We would rather you did the comparison honestly than switch on a hunch and regret it in a month.
