Every article you will find on this subject was written by somebody who sells redesigns. This one included. So rather than another list of feelings — it looks dated, it does not feel modern — here are seven tests you can run on your own site this afternoon, most of them with a number attached, followed by an honest section on when a redesign is the wrong purchase entirely.
Work through them in order. The first four are the ones costing you money.
Test 1: Does it pass Google's Core Web Vitals?
Core Web Vitals are the three performance measurements Google publishes and uses as part of how it assesses page experience. They are the closest thing you have to an objective grade for how your site feels to use, and the thresholds are public:
- Largest Contentful Paint (LCP) — how long until the main content appears. Good is 2.5 seconds or less.
- Interaction to Next Paint (INP) — how quickly the page responds when someone taps or clicks. Good is 200 milliseconds or less.
- Cumulative Layout Shift (CLS) — how much the page jumps around while it loads. Good is 0.1 or less.
Two details matter and are almost always left out. Google assesses these at the 75th percentile of page loads, so it is not your fastest visit that counts — it is roughly your fifth-worst out of every twenty. And mobile and desktop are measured separately, so a site that sails through on a desktop with office broadband can still fail for the customer standing in a car park.
Run your homepage and your main service page through PageSpeed Insights, then check the Core Web Vitals report in Google Search Console if you have it. Search Console is the better source, because it reports what real visitors experienced rather than one simulated load.
How to read the result: failing one metric is usually fixable without touching the design — oversized images, a heavy homepage slider, a pile of tracking scripts, no caching. Failing all three on mobile, on a site that has already been tuned once, is a foundations problem.
Test 2: Is the mobile version the real version?
Google is unambiguous here. It crawls with a smartphone agent and uses the mobile version of a site's content for indexing and ranking, and its documentation warns that if your mobile site has less content than your desktop site you should fix it, because indexing comes from the mobile site.
That turns a very common shortcut into a ranking problem. Plenty of older sites simply hide sections on small screens to keep the layout tidy. Anything hidden that way is not only invisible to the customer on a phone — it is effectively invisible to Google as well.
Open your site on your own phone, on mobile data rather than office wifi, and check the basics:
- Is every section that exists on desktop also reachable on mobile?
- Does tapping the phone number actually dial it?
- Can you complete the contact form with a thumb, including any dropdowns?
- Do you ever have to pinch to read body text or zoom to hit a button?
- Does a pop-up cover the screen before you have read anything?
A site that fails several of these was designed for desktop and squeezed down afterwards. That is structural, and it is the single most common honest reason to rebuild.
Test 3: Can a stranger complete your main action in a minute?
Decide what one thing you most want a visitor to do — call, book, request a quote, buy. Then ask three people who have never seen the site to do it while you stay quiet and watch. Not colleagues; people who do not already know what you sell.
Time them. Watch where they hesitate. The failures are almost always the same short list: they cannot tell within five seconds what the business actually does, the price question is never addressed anywhere, the call to action is a grey button below three screens of scrolling, or the form asks for eleven fields when it needs three.
None of that is a design taste problem, and none of it needs a rebuild to diagnose. It is worth doing before you brief anybody, because it tells you what the new site has to fix.
Test 4: Are you getting traffic but not enquiries?
This is the test that decides whether the website is the problem at all. Pull up two numbers from the last three months: how many people visited, and how many enquiries you received.
- Low traffic, reasonable conversion. The site is doing its job and nobody is finding it. That is a search and marketing problem, not a design one — see our explainer on what SEO is and how it works before you spend anything on a rebuild.
- Reasonable traffic, almost no enquiries. Now the site is a fair suspect. Check the obvious mechanical failures first: send yourself a test message through every form, from a phone, and confirm it arrives and does not land in spam. Broken forms are more common than anybody admits.
- Traffic falling steadily over a year or more. Look at which pages lost it before assuming the design is at fault. A single technical fault, a lost listing or a competitor publishing better content will all show up this way.
Test 5: Can you change a price without phoning anybody?
Try to do something small and ordinary: update a price, swap a photograph, add a new service page, correct your opening hours. If that requires a developer, a support ticket and a three-day wait, the site is not really yours to run.
The cost of that is quiet but real. Prices go stale, seasonal offers never go up, the team you are proud of is still the team from four years ago, and the blog stops. Being able to edit your own site is one of the strongest arguments for a rebuild, because it is the one that keeps paying back every month afterwards.
Test 6: Is anything on it wrong, broken or unsafe?
Walk the whole site once with a notepad and check for the things that quietly cost you trust:
- Services you no longer offer, or prices you no longer charge.
- Staff who left, and a copyright year in the footer that is out of date.
- Links that lead to a 404 page, and images that no longer load.
- A padlock missing from the address bar. Every site needs HTTPS now, including one with no checkout, and browsers will warn visitors if it is absent.
- A content management system or plugins that are years out of date — the most common route by which small business sites get compromised. Our guide to website maintenance costs covers what keeping this current actually involves.
- Obvious accessibility failures such as pale grey text, images with no alternative text, or a form whose fields have no labels. These matter legally as well as practically — see our guide to ADA compliance for small business websites.
Most of this list is maintenance rather than redesign. But if the list runs to two pages, the real finding is that nobody has been looking after the site, and a new one will be in the same state in three years unless that changes too.
Test 7: Put it side by side with three competitors
This is the test every redesign article opens with, and it belongs at the end — because it is the most subjective and the easiest to over-read. Open your site and three competitors on the same screen and look at them as a customer would in the two seconds before deciding who to call.
Be specific about what you see rather than reaching for "dated". Do their sites show real photographs of real work while yours shows stock images? Do they show prices or a starting price while yours does not? Do they show reviews, case studies or named clients? Is their contact route obvious and yours buried?
Those differences are mostly content, not design. It is entirely possible to close the gap without a rebuild — and knowing that before you speak to an agency is worth a lot.
Refresh or rebuild?
Sort everything you found into two columns.
A refresh is enough when the problems are on the surface: tired colours, weak copy, stock photography, an unclear call to action, missing proof, one or two slow pages, a page you need that does not exist yet. All of that can be done on the site you already own, usually for a fraction of a rebuild, and usually faster.
A rebuild is justified when the problems are in the foundations: the layout genuinely does not work on a phone, the structure cannot carry the pages you now need, nobody can edit it, the platform is no longer supported or secure, or performance stays poor after the easy fixes have been made. Two or more of those together is a rebuild.
If you get there, our guides on what a website actually costs and how to choose a web design company cover what to ask for and what a fair quote contains.
When a redesign is the wrong fix
Four situations where we would tell you not to spend the money yet:
- Almost nobody is visiting. A better site shown to the same handful of people produces roughly the same handful of enquiries. Fix visibility first — search, your Google Business Profile, wherever your customers actually look — then improve the site with real traffic to measure against.
- You are not sure what you want the site to say. A redesign cannot decide your positioning for you. If the current copy is vague because the offer is vague, a new layout just presents the same vagueness more attractively.
- The real objection is price or trust. If enquiries arrive and then go quiet, the problem is usually in what happens after the click — response time, quoting, proof, follow-up. None of that lives on the website.
- The last redesign was under two years ago and nothing has been added since. Rebuilding on the same cycle of neglect buys you the same outcome. A content plan is cheaper and works better.
Before you brief anyone, do these four things
Whatever you decide, half an hour of preparation protects you.
- Record your baseline. Write down current monthly visits, enquiries, your PageSpeed scores and your top ten pages by traffic. Without this you cannot tell afterwards whether the redesign worked.
- Save your existing URLs. Export the list of every page address on the site today. This is the single most valuable document in a redesign.
- Insist on redirects in writing. Rankings and links attach to individual addresses, not to your domain in general, and our guide to redesigning a website without losing your Google rankings sets out exactly how that map gets built. If a redesign changes a URL and does not redirect the old one to the new one, that page starts again from nothing. This is the most common way a redesign loses traffic, and it is entirely avoidable.
- Do not delete content that is working. If a page brings in visitors, it moves to the new site. Shorter and tidier is a design goal, not an SEO one.
In summary
Run the seven tests before you accept anybody's diagnosis, including ours. Performance, mobile, the one-minute task and the traffic-to-enquiry ratio will tell you more than any opinion about whether a design looks current. If what you find is cosmetic, ask for a refresh. If it is structural, rebuild — but keep your URLs, keep your best content and write down your baseline first.
Frequently asked questions
How do I know if my website needs a full redesign or just an update?
Sort the problems into cosmetic and structural. Dated colours, tired photography, weak copy, an unclear call to action and a missing page are all fixable on the site you already have. A rebuild is justified when the problems are in the foundations: the layout does not work on a phone, the page structure cannot support the pages you now need, nobody can edit it, or the underlying software is no longer supported. If your list is mostly cosmetic, ask for a refresh and keep the money.
How slow is too slow for a business website?
Google publishes the thresholds, so you do not have to guess. Largest Contentful Paint should be 2.5 seconds or less, Interaction to Next Paint 200 milliseconds or less, and Cumulative Layout Shift 0.1 or less. Those are assessed at the 75th percentile of real page loads, measured separately for mobile and desktop, so passing on office broadband is not the same as passing. Failing one of the three is usually a tuning job rather than a rebuild.
Will a redesign improve my Google rankings?
Not on its own, and it can easily make things worse. Rankings attach to individual URLs, so a redesign that changes addresses without proper redirects, or that ships with less content than the old site, commonly loses traffic for months. A redesign helps search when it fixes real problems: slow pages, content missing on mobile, a structure Google cannot follow, or thin pages that never answered the question. Ask any agency how they will preserve your existing URLs before you sign.
How often should a business website be redesigned?
There is no correct interval, and the common claim that you need a rebuild every two or three years mostly serves the people selling them. A site that is fast, works properly on a phone, can be edited by your own team and still describes what you sell can run for many years with regular content updates. Let the tests decide it rather than the calendar.
What does a website redesign cost?
Roughly the same as building the equivalent site from scratch, because most of the work is design, content and build rather than deletion. Our own published packages start at 499 dollars for a five page static website and 999 dollars for a five page dynamic website, with larger builds quoted on scope. Budget separately for photography, copywriting and the redirect mapping, which are the three items most often left out of a redesign quote.
If you have run the tests and want a second opinion on what you found, tell us what your site is doing and we will tell you honestly whether it needs rebuilding — our web design service handles refreshes as well as full rebuilds.
