12 UX Mistakes That Kill Website Conversions (and How to Fix Each One)

A website can look stunning and still lose most of the people who visit it. Conversions rarely die in one dramatic failure. They leak through small moments of confusion, effort and doubt. Here are the twelve UX mistakes we fix most often on business websites, and what to do instead.

#1. Is your headline clear in five seconds?

If a visitor cannot say what you do, for whom, and why you, they leave. Replace clever slogans with a plain statement. "Shopify stores for fashion brands, designed and built in four weeks" beats "Elevating digital commerce".

#2. Do your calls to action stand out?

One primary action per screen, in a colour nothing else uses. When "Book a call", "Download", "Subscribe" and "Learn more" all look the same, none of them win. Make the main action obvious and the secondary one quieter.

#3. Are you offering too many choices?

Every extra option slows the decision. Long menus, ten services on the homepage and three different contact methods in one block create hesitation. Group, simplify and guide people to the next logical step.

#4. Are your forms too long?

Each additional field costs completions. Ask only what you need to reply well: name, email or phone, and a short message. Qualify leads on the call, not in the form. Use the right keyboard types on mobile and allow autofill.

#5. Is the site slow on a phone?

Slow pages lose visitors before they see your offer. Compress images, cut unused scripts and test on mobile data, not office Wi-Fi. Our Core Web Vitals guide explains exactly what to fix.

#6. Was the mobile layout an afterthought?

Most visits are on phones, so design for the thumb first. Tap targets at least 44 pixels high, readable text without zooming, sticky calls to action where helpful, and no sideways scrolling. Test every page at a narrow width before launch.

#7. Where is the proof?

People believe other customers more than they believe you. Put case studies, client logos, reviews and real photos next to the decision point, not on a separate page nobody visits. Specific proof beats vague praise.

#8. Are you hiding how the process works?

Uncertainty stops enquiries. Explain what happens after someone contacts you, how long things take and what affects the cost. You do not need a price list, but you do need to remove the fear of the unknown.

#9. Do error messages help or blame?

Tell people exactly what went wrong and how to fix it, next to the field. "Please enter a 10-digit mobile number" helps. A red border with "Invalid input" at the top of the form does not.

#10. Do pop-ups interrupt too early?

A pop-up that covers the page before someone has read a sentence is a door slammed in their face. Trigger offers on engagement (scroll depth, time on page or exit intent on desktop), keep them easy to close and never block content on mobile.

#11. Are your images generic stock?

Real photos of your team, work and products build trust that stock photography cannot. If you must use stock, choose images that show context, not smiling people pointing at laptops. See how we approach product photography.

#12. Is your navigation built for you or for visitors?

Label menus with the words visitors use. "Solutions" and "Offerings" mean little. "Websites", "SEO" and "Pricing approach" mean a lot. Keep the main menu short and put everything else in a well-organised footer.

#How do you prioritise fixes?

Measure enquiries and sales after each change, not just clicks. A change that increases clicks but not leads has only moved the problem.
