How do you know if your business needs a new website?

Plenty of websites that look dated are doing their job, and plenty that look fine are quietly failing. Five checks tell you which you have before you spend anything, including when the honest answer is to keep what you've got.

Your business needs a new website when the current one fails at something that costs you customers: it breaks on phones, it loads too slowly, you can't update it yourself, it no longer describes what you sell, or visitors arrive and leave without getting in touch. If it passes all five, you probably don't need a new website, however dated it looks. Most rebuild decisions start from how a site looks. The ones that pay back start from what it fails to do.

Zenith Digital builds and migrates websites for a living, so this is an agency telling you when not to buy the thing it sells. The five checks below take under an hour and need no technical knowledge.

TL;DR

• Run the keep-or-rebuild test: mobile, speed, editing, message and enquiries.
• Passing all five means keep it and spend on content or visibility instead. One or two specific failures usually means fix, not rebuild.
• Failing on mobile or editing usually means the platform itself is the constraint, and that is when a rebuild pays for itself.

Who this is for

Business owners who have a website, feel it is overdue for replacement, and want to know whether that feeling is worth several thousand pounds. If you have no website at all, you need one, and this article is not for you.

The keep-or-rebuild test

Five checks, each answered yes or no. Run them on the site you have today, not the one you imagine replacing it with.

1. Does it work properly on a phone?

Open the site on your own phone and try to do the one thing a customer comes to do: find a price, book, or send an enquiry. If text needs zooming, buttons are hard to tap or the form breaks, it fails. This check matters twice over, because Google uses the mobile version of a site for indexing and ranking. A site that is broken on phones is broken for search as well as for customers.

2. Is it fast enough?

Put your homepage and your most important service page into Google's free PageSpeed Insights. It reports the three Core Web Vitals, and Google's own targets are: main content loaded within 2.5 seconds, a response to taps and clicks within 200 milliseconds, and a layout that doesn't jump around as it loads. Missing one target by a little is fixable on almost any site. Missing all three badly often points at the platform or the theme underneath.

3. Can you change it yourself?

Try to add a new page, change a price and swap a photo without help. If any of those means emailing a developer and waiting, the site is costing you in delay every time the business changes. This is the check most often failed by sites that still look fine.

4. Does it still describe what you sell?

Read the homepage as if you were a new customer. Are the services, prices and the kind of client you want today the ones on the page? Businesses move faster than their websites. A site that describes the company you were two years ago attracts the customers you had two years ago.

5. Does it turn visitors into enquiries?

Check two numbers: how many people visit, and how many get in touch. Google Search Console's Performance report shows the searches bringing people in. If visitors arrive and almost nobody enquires, the pages are failing to persuade. If almost nobody arrives, the problem is visibility, and a new design alone won't fix that.

What your score means

When is a new website the wrong answer?

When the site passes the test and you are simply tired of looking at it. That is a brand decision, not a website decision, and new photography and rewritten copy on the existing site will usually get you most of the way for a fraction of the cost.

It is also the wrong answer when the real problem is that nobody finds you. A beautiful new site with no visitors is still a site with no visitors. If check five shows low traffic rather than low conversion, the money belongs in search visibility first.

When does a new website pay for itself?

When the failures sit in the foundations, where no amount of patching reaches. Two situations from our own case studies show the pattern.

Both are written up in full: the Bel'Istria migration and the Knode AI rebuild.

What most people get wrong

They brief the new site by describing how the old one looks. "It feels dated" becomes the whole brief, and the rebuild fixes the look while carrying every real failure across: the same slow pages, the same missing service pages, the same enquiry form nobody uses. A rebuild worth paying for is briefed from the failed checks. The look follows from those, not the other way round.

Can you run this yourself, or do you need help?

You can run all five checks yourself, and you should before talking to anyone who sells websites, us included. Professional help earns its fee when the answer is rebuild and the current site has search traffic worth protecting, because that is where a move goes wrong. Our website migration service exists for exactly that case.

The takeaway

Decide from failures, not from looks. Pass all five checks and your money is better spent on content and visibility. Fail on mobile or editing and a rebuild is usually justified. If you do rebuild, whether a redesign will hurt your Google rankings covers what to protect, and how much a Wix Studio website costs covers the budget.
