Your website might be losing you customers right now, quietly, without you knowing. Most business websites make the same handful of mistakes that turn visitors away before they ever enquire. The good news: every one is fixable. Here are the 10 most common — and how to fix them.

1. It loads too slowly

Visitors leave if a page takes more than a few seconds. Slow sites also rank worse on Google. Fix it by optimising speed — images, hosting and code. It’s often the single highest-impact fix.

2. It doesn’t work well on mobile

Most visitors are on phones. If your site is hard to use on mobile, you’re losing the majority. A mobile-first design isn’t optional — it’s where your customers are.

3. It’s not clear what you do

Visitors decide in seconds. If your homepage doesn’t instantly say what you offer and who it’s for, they leave. Lead with a clear, benefit-focused headline.

4. There’s no clear call to action

If you don’t tell visitors what to do next — call, enquire, book — most won’t. Add clear, prominent calls to action on every page.

5. It’s hard to contact you

Hidden or missing contact options cost enquiries. Make your phone, WhatsApp and enquiry form easy to find on every page.

6. It can’t be found on Google

A beautiful site no one finds is wasted. If it wasn’t built with SEO in mind, you’re invisible to people searching for what you offer.

7. It looks outdated

An old-looking site makes customers question your credibility. In a competitive market, a dated design quietly sends people to competitors who look more professional.

8. The content is all about you

Visitors care about their problems, not your company history. Frame your content around what you do for the customer and the results they get.

9. There’s no trust or proof

Without reviews, testimonials or credentials, visitors hesitate. Add social proof — Google reviews, testimonials, client logos — to reassure them.

10. It’s not secure (no HTTPS)

Browsers warn visitors away from non-secure sites, and Google ranks them lower. HTTPS is a basic must-have — and part of overall website security.

Your website is your hardest-working salesperson — but only if it’s fast, clear, findable and trustworthy. Fix the leaks and it starts earning.

The bottom line

Most websites lose customers not through one big flaw but through several small, fixable leaks — slow speed, poor mobile, unclear messaging, weak calls to action. Fix these ten, and your website stops quietly turning people away and starts bringing in the enquiries it should.

Frequently asked questions

Why is my website not getting enquiries?

Common reasons include slow loading, poor mobile experience, unclear messaging, weak or missing calls to action, hard-to-find contact options, and not being found on Google. Fixing these usually lifts enquiries significantly.

What’s the most important thing to fix on a website?

Usually speed and mobile experience — they lose the most visitors and also affect Google ranking. After that, clear messaging and strong calls to action have the biggest impact.

Does website design affect sales?

Yes — an outdated or confusing design makes visitors question your credibility and leave, while a fast, clear, trustworthy site turns more visitors into enquiries and customers.

Do I need HTTPS on my website?

Yes — HTTPS is essential. Browsers warn visitors away from non-secure sites and Google ranks them lower. It’s a basic security must-have.
