Signs your website needs a redesign (and how to check each one yourself)

A visitor forms an opinion about your website in about 50 milliseconds, long before they’ve read a single word of your copy (Google Research, citing Lindgaard et al., Behaviour & Information Technology). Most advice on “signs you need a redesign” doesn’t hold up to that kind of scrutiny either. It’s a checklist of feelings: your site “looks dated,” it “feels clunky,” it “doesn’t feel like you anymore.” None of that tells you whether to spend the money.

This guide replaces the feelings with eight specific, checkable signs. Each one comes with the free tool or number you can look up in under five minutes, so you finish with actual diagnostic results instead of a hunch.

Key Takeaways

• Most “signs you need a redesign” advice describes a feeling. This guide gives you a specific free tool or number for every sign instead.
• Site speed has a measurable, near-linear relationship with both bounce rate and conversion rate, not just a “nice to have” UX quality.
• Low conversion rate, not low traffic, is the reason most commonly cited by businesses that redesign (GoodFirms, 2021 survey).
• If two or more of these checks come back failing, a redesign will likely pay for itself in recovered leads faster than a cosmetic refresh would.
• A newer sign worth checking: whether AI assistants cite your business or your competitors when someone asks about your category.

1. Your site fails Google’s own load-time benchmarks

If your site takes more than three seconds to load, you’re likely losing over half your mobile visitors before they see anything at all.

Run PageSpeed Insights against your homepage and your busiest landing page. It scores your Core Web Vitals and gives you a plain-English load time. As that number climbs, so does the chance a visitor leaves before the page finishes rendering. Bounce probability rises 32% as load time goes from one to three seconds up to one to five seconds, and 106% by the time it reaches one to six seconds. Mobile visitors are even less patient: 53% abandon a page that takes longer than three seconds to load (Google/SOASTA Research, via Think with Google, 2016).

The same speed problem shows up in your conversion rate, not just your bounce rate. Portent’s site-speed study tracked roughly 100 million pageviews across 20 B2B and B2C sites. Conversion rate fell steadily as load time increased from one to five seconds. A B2B site that loads in one second converts, on average, three times higher than one taking five seconds; for ecommerce and B2C sites, the gap is 2.5 times. A red PageSpeed score is a revenue problem.

2. It doesn’t pass a mobile usability check

If your site isn’t comfortably usable on a phone, you’re failing the device most of your visitors are already using.

UK adults now spend 77% of their online time on smartphones (Ofcom, Online Nation 2025), and smartphone ownership sits at around 78% of the UK population overall (Ofcom, Communications Market Report 2025). If a visitor lands on your site from their phone and has to pinch-zoom to read a paragraph or misses a tap target by a few pixels, you’ve lost them before they’ve evaluated anything you actually sell.

Google retired its standalone Mobile-Friendly Test in December 2023, so run your homepage through PageSpeed Insights instead and check the mobile report, or open Chrome DevTools, switch to a mobile device emulation view, and run a Lighthouse mobile usability audit. Look for three specific failures: text that’s too small to read without zooming, tap targets placed too close together, and content that forces horizontal scrolling.

3. Traffic is steady, but leads aren’t following

A site that gets visits but not enquiries usually has a conversion problem, not a traffic problem, and it’s the single most common reason businesses redesign.

Check your GA4 conversion rate (Reports → Engagement → Conversions, or a custom event report if you track enquiries as goals) against your traffic. If visits have held steady while form submissions or calls have dropped, the design is doing something to lose people between arrival and enquiry, whether that’s a buried contact form, an unclear offer, or a call-to-action that’s easy to miss. In a 2021 survey of 672 web designers, low conversion rate was the most commonly cited reason businesses redesign (80.8% of projects), followed by high bounce rate (65.4%), poor user experience (61.5%), unresponsive design (53.8%), and outdated visual design (38.5%) (GoodFirms).

Most “signs you need a redesign” articles treat outdated design as the headline trigger. The data says otherwise: it’s the least-cited reason on this list, well behind conversion and usability problems that a fresh coat of paint alone won’t fix.

4. It fails a basic accessibility check

If your site can’t be scanned cleanly by a free accessibility tool, you’re likely excluding real customers and creating legal exposure at the same time.

Run your homepage through the WAVE accessibility checker, a free browser tool that flags contrast failures, missing alt text, and unlabelled form fields in seconds. You won’t be alone if it comes back red: 94.8% of the top one million homepages have at least one detectable WCAG 2 A/AA failure, averaging 51 errors per page. Six recurring issues, low-contrast text and missing alt text among them, account for 96% of all detected errors (WebAIM Million, 2025). That’s the default state of the web, which makes fixing it a genuine differentiator rather than a box-ticking exercise.

5. Your brand has moved on, but your site hasn’t

If your logo, offer, pricing, or positioning have changed since the site launched and the site still reflects the old version, it’s actively working against you.

Walk through your own site as a stranger would and note every place it’s out of date: services you no longer offer, pricing that’s changed, testimonials from clients you no longer work with, team photos of people who’ve left. List each mismatch as you find it. Three or four is a content update; a dozen usually means the site was built around a version of the business that no longer exists, which is a structural problem, not a copy-editing one. Each mismatch is also a small credibility gap on its own, and visitors who spot one start wondering what else is out of date, including the thing they actually came to check, like whether you’re still in business.

6. You can’t update it without calling someone

If every small copy change requires a developer, your website is a liability, not a marketing asset, and that’s a redesign trigger competitors rarely mention.

Try editing a single line of text or swapping a testimonial yourself, right now, without opening a support ticket. Time it. If you can’t find where to make the change, or the change requires touching code, your site’s content can only ever be as fresh as your last invoice to a developer, which in practice means it isn’t fresh at all. A modern CMS should let you make routine edits in minutes. That matters for more than convenience: a site nobody updates also stops sending the freshness signals search engines and AI systems use to judge whether your information is current, so this sign compounds with Sign 8 below.

7. You’ve checked yourself against a competitor and lost

If a competitor’s site now looks and functions more credibly than yours to a new visitor, that gap compounds every day you leave it.

Open your site and your closest competitor’s side by side, on the same device. Time how long each takes to load using the same PageSpeed check from Sign 1. Try each on your phone, using the same mobile usability check from Sign 2. Ask which one makes it clearer, in five seconds, what the business does and why you’d choose it over the alternative. This isn’t a vanity exercise: a visitor comparing options rarely tells you they picked the other company because your site felt harder to trust or slower to use. They just don’t enquire, and the traffic-without-leads pattern from Sign 3 is often the first place that shows up.

8. AI answer engines cite your competitors, not you

If asking ChatGPT, Perplexity, or Google’s AI Overview about your category surfaces competitors and not you, your site likely isn’t structured clearly enough to be read and cited, a newer, checkable version of “you’re falling behind.”

This is the sign every other “redesign checklist” on the market skips entirely, and it takes under a minute to check. Search your business and category, once on Google and once in an AI assistant, and see who actually gets named. Earning a citation comes down to clear page structure, consistent business information across your site, and content that states facts plainly enough for a language model to extract and attribute. A site that’s hard for a human to parse quickly is usually just as hard for the systems now answering questions on your behalf.

The eight checks at a glance

Sign	How to check it	Counts as failing if
1. Slow load time	PageSpeed Insights	Load time over three seconds, or Core Web Vitals in the red
2. Mobile usability	PageSpeed Insights mobile report, or Lighthouse in Chrome DevTools	Text too small to read, tap targets too close together, or horizontal scrolling
3. Traffic without leads	GA4 conversion rate against traffic	Visits hold steady while enquiries fall
4. Accessibility	WAVE	Any contrast, alt text, or form-label errors flagged
5. Brand drift	Walk your own site as a stranger	More than a handful of outdated services, prices, or testimonials
6. Can’t self-edit	Try changing one line of copy yourself	You can’t do it without a developer
7. Competitor gap	Side-by-side comparison on the same device	Theirs loads faster or explains the offer more clearly
8. AI citations	Ask ChatGPT, Perplexity, or Google’s AI Overview about your category	Competitors get named and you don’t

What this actually means for you

None of these eight checks takes more than five minutes, and together they take less time than a single sales call. If you failed one, it’s worth fixing on its own, and a few of them (speed, accessibility) can be improved without a full rebuild. If you failed two or more, treat them as compounding rather than separate. A slow, hard-to-read site that also loses the AI-citation battle is losing leads for several reasons at once, and a partial fix rarely closes that gap.

A useful way to prioritise: start with whichever failed check sits closest to the point where a visitor actually decides to contact you. A slow load time (Sign 1) or a broken mobile experience (Sign 2) loses people before they see your offer at all, so those tend to be worth fixing first. Content drift (Sign 5) and CMS limitations (Sign 6) matter, but they cost you conversions at the margin rather than turning visitors away outright. Writing a brief once you’re ready to move forward is the fastest way to turn these findings into a scoped project instead of an open-ended worry.

Run the checks, then decide

Two or more failed checks is the threshold where a redesign will likely pay for itself in recovered leads faster than a cosmetic refresh would. Run each test above yourself before you decide anything, since a real number beats a hunch every time.

Once you know which signs you’re failing, the next step is choosing the right agency to fix them, and after that, writing a brief that gives them everything they need to get it right the first time.
