Most visitors decide within seconds whether to stay on a website. Small design mistakes, the kind business owners stop noticing on their own site, can quietly send customers to competitors. Here are 15 to check for.

First impressions

1. Unclear headline. If visitors can't tell what you do in five seconds, they leave.
2. Auto-playing sliders. Rotating banners distract, slow the page, and most visitors never see slide two.
3. Stock photos everywhere. Generic images feel impersonal. Real photos of your work and team build trust.
4. Cluttered layouts. Too many colours, fonts and elements competing for attention.

Mobile and speed

5. Not mobile-friendly. Tiny text, overlapping elements and buttons too small to tap.
6. Slow loading. Heavy images and too many scripts. See why WordPress sites get slow.
7. Pop-ups that block everything as soon as the page opens, especially on mobile.

The fix for most of these: mobile-first design.

Navigation and content

8. Confusing menus. Too many items or vague labels like "Solutions" with no context.
9. Walls of text. No headings, bullet points or white space.
10. Everything on one page. Without separate service pages, you can't speak to each customer's needs or rank for each service.
11. Outdated information. Old prices, past events or a copyright year from years ago signal a neglected business.

Contact and conversion

12. Hidden contact details. Phone and WhatsApp should be easy to find on every page.
13. Weak or missing calls to action. Tell visitors exactly what to do next.
14. Long, demanding forms. Ask only what you need.
15. No proof. No testimonials, reviews, client logos or examples of work.

How to audit your own site

1. Open your site on your phone and try to contact yourself in under 30 seconds.
2. Ask someone unfamiliar with your business what you do after five seconds on the homepage.
3. Test speed on PageSpeed Insights.
4. Check every page for outdated information.

If you find several of these problems, a focused redesign can usually fix them quickly and turn more visitors into enquiries.
