Website Design Mistakes To Avoid in 2027: 14 That Quietly Cost Businesses Enquiries

The short answer

The website design mistakes that cost businesses the most are rarely about style. They are vague homepages, slow pages, missing proof, hidden prices, forms that ask too much, one page trying to sell every service, and redesigns launched without redirects. In 2027, two more join them: looking like every other generated site, and pages machines cannot read.

Each mistake below is common, measurable and fixable without a full rebuild. They are listed roughly in the order a visitor would meet them, and each comes with the fix.

1. A homepage that does not say what you do

Visitors decide within seconds whether they have landed in the right place. A homepage that opens with a slogan, a mood video or "welcome to our website" makes them work out what you sell, and many leave instead. The first screen should state what you do, for whom and where, in plain words.

Fix: rewrite the headline so a stranger could repeat back what you do after five seconds, add a one-line qualifier for who it is for, and give one primary button. Our guide to homepage messaging covers the structure.

2. Designing on a desktop and checking the phone last

Most visits to most business websites now come from phones, yet many sites are still designed on large monitors and squeezed onto small screens at the end. The result is buried calls to action, tiny text, menus that hide the important pages and forms that are painful to fill in with a thumb.

Fix: review every design on a phone first, decide what the first screen on a phone must contain, and test the main tasks, finding a service and getting in touch, one-handed on a real device.

3. Heavy hero videos and slow pages

A full-screen video or a large image carousel at the top of the homepage is often the slowest thing on the site, and it loads exactly when visitors are deciding whether to stay. Slow pages lose visitors and weaken search performance. Google treats a main element appearing within 2.5 seconds as good.

Fix: serve a light poster image first and load video only when it helps, compress and resize images, cut unused fonts and scripts, and test on a mid-range phone over mobile data. The full diagnosis is in why your website is slow.

4. Stock photos and generic visuals

Visitors have learned to ignore generic stock imagery: the handshake, the smiling team that is clearly not your team, the abstract city at dusk. It signals that nothing on the page is specific to you. Real photographs of your people, premises, products and work are almost always more persuasive, even when less polished.

Fix: budget for one professional photo session, use real project images on service pages, and where you must use illustration or stock, choose images that explain something rather than decorate.

5. One services page for everything

A single page listing every service with a sentence each fully answers no one's question and ranks for nothing in particular. Customers searching for a specific service want to see that exact service explained: what it includes, who it suits, how it works and what it costs. Search engines reward the same specificity.

Fix: give each service customers buy separately its own page with scope, process, price guidance, proof and a call to action. Our guide to what pages a business website should have sets out the full list.

6. Hiding prices completely

When a website gives no indication of cost, visitors assume the worst, or leave to find a competitor who explains it. Not every business can publish a fixed price, but almost every business can say where prices start, give typical ranges or explain what drives the cost. Silence on price costs trust and wastes sales time.

Fix: publish starting prices, ranges or packages, or a short explanation of how pricing works with a worked example. You will receive fewer enquiries from people who could never afford you, and more from people who can.

7. Contact forms that ask too much

Every extra required field gives a visitor another reason to stop. Forms that demand a budget, company size, phone number and a detailed description before someone has decided to trust you lose enquiries. So do contact pages that hide the phone number, and sites where the only way to get in touch is buried in the footer.

Fix: ask only for what you need to reply well, usually name, contact method and a message. Put a clear contact action in the header and at the end of every service page, and test that every submission arrives.

8. Proof that is vague or missing

Phrases such as "trusted by leading brands" and "quality you can rely on" persuade no one, because every competitor says them. Visitors look for evidence: named clients, specific results, real reviews, before-and-after work, credentials that matter in your field. A site with no proof forces visitors to take your word for it, and most will not.

Fix: collect three to five case studies with a specific outcome each, ask happy clients for named reviews, and place proof on the service pages where decisions happen, not only on a separate page.

9. Sliders, autoplay and motion that gets in the way

Rotating sliders, autoplaying video with sound and animations on every element slow the page and pull attention away from the content that matters. Rotating messages are rarely seen past the first, and constant motion makes pages harder to read and use, particularly for people with vestibular or attention difficulties.

Fix: replace sliders with one clear message, keep motion for moments that explain or give feedback, and respect the reduced-motion setting in visitors' devices. Motion should earn its place, which is the point we made in web design trends for 2027.

10. Text people cannot read

Light grey text on white, small type, text set over busy photographs and words baked into images all make content harder to read, and text inside images cannot be read by screen readers or search engines. Low contrast is among the most common accessibility failures on business websites, and accessibility is now a legal requirement in many markets.

Fix: meet WCAG 2.2 AA contrast, set body text at a comfortable size, keep text as real text rather than images, and test with a keyboard and an accessibility checker. The legal side is in website accessibility compliance.

11. Navigation built around your organisation chart

Menus often mirror how a company is organised internally, with department names, product codes and clever labels, rather than how customers think about their problem. Visitors scan navigation for the words in their own heads. When the label does not match, they assume what they need is not there.

Fix: use plain labels in customers' language, keep the main menu to around five to seven items, put the most-visited pages first, and check your site search and enquiries for the words people actually use.

12. Redesigning without redirects

When a new website changes page addresses without permanent redirects from the old ones, every bookmark, every link from other sites and every ranking those pages had is broken at once. It is the most common reason traffic collapses after a relaunch, and it is entirely preventable with a redirect map prepared before launch.

Fix: export every old URL, map each one to its closest new page with a 301 redirect, and check Search Console for not-found errors in the weeks after launch. The method is in redesigning without losing rankings.

13. Looking like every other website

New in 2027: AI tools and popular templates make it easy to produce a polished site, which means many polished sites now look the same, with similar layouts, gradients, illustrations and phrasing. When everything looks competent, competence stops being a reason to choose you. Generic design makes a business forgettable.

Fix: invest in what only you have: real photography, specific language, an identity system with distinctive elements and examples of real work. We wrote about the causes in why every website looks the same.

14. Pages machines cannot read

Also new: a growing share of visits begins with an AI assistant reading your pages to answer a customer's question. Content hidden inside images, scripts or interactions, vague headings and missing basic facts make your site hard to quote accurately. If an assistant cannot understand what you offer, it recommends someone it can.

Fix: keep important content as real text, open each section with a direct answer, state facts such as services, locations and price guidance plainly, and add structured data. Schema markup for AI search covers the technical part.

How to find these mistakes on your own site

Ask five people who do not know your business to find a specific service and get in touch, on their own phones, while you watch without helping. Then check analytics for pages people leave quickly and Search Console for errors. Most of the mistakes above show up within an hour of honest testing.

For a structured review with a score for each area, use our website audit checklist. If the site gets visitors but few enquiries, traffic but no leads sets out what to fix first.
