10 Website Mistakes That Are Driving Your Customers Away

Your Website Is Driving Customers Away Without You Knowing It

Having a website is good. Having a website that converts is better. Many businesses in Senegal invest in a site but see no results. The reason? Common mistakes that drive visitors away within seconds.

Here are the 10 most frequent mistakes and how to fix them.

Mistake 1: A Slow Website

The problem: In Senegal, many of your clients browse on 3G or 4G with an unstable connection. If your site takes more than 3 seconds to load, 53% of visitors leave without even seeing your content.

The solution: Optimize images (WebP format), use fast hosting, minimize JavaScript code. At Kolonell, our sites load in under 2 seconds even on 3G thanks to Next.js and automatic optimization.

Mistake 2: No Mobile Version

The problem: Over 80% of Senegalese access the internet via smartphone. A site that displays poorly on mobile is a site that loses 80% of its visitors.

The solution: A "mobile-first" design — design for the smartphone first, then adapt for desktop. All our sites are tested across at least 10 different screen sizes.

Mistake 3: No Visible WhatsApp Number

The problem: In Senegal, people prefer WhatsApp over email. If your WhatsApp number is not immediately visible, you lose the preferred contact method of your customers.

The solution: A floating WhatsApp button on every page, visible at all times. This is a standard we integrate on every Kolonell site.

Mistake 4: Copied or Generic Content

The problem: Texts like "We are a dynamic company at the service of our clients" say nothing and convince nobody. Google also penalizes duplicate content.

The solution: Unique content that speaks directly to YOUR customers, with YOUR specific advantages. "We deliver your thieboudienne in 30 minutes across all of Dakar" is 10 times more effective.

Mistake 5: No Clear Call to Action

The problem: The visitor arrives on your site, looks around... and does not know what to do next. No "Book" button, no "Order," no "Contact us."

The solution: A clear and visible CTA (call to action) on every page. Use action verbs: "Book your table," "Get a free quote," "Order now."

Mistake 6: Outdated or Amateur Design

The problem: A 2010-era design with garish colors, Comic Sans fonts, and animated GIFs destroys your credibility instantly.

The solution: A modern, clean design with colors consistent with your brand. Minimalism inspires trust.

Mistake 7: No SEO

The problem: Your site exists but nobody finds it on Google. It is like having a shop on a street with no foot traffic.

The solution: Optimize titles, descriptions, local keywords, and your Google My Business listing. SEO is not optional — it is what makes your investment profitable.

Mistake 8: No Testimonials or Social Proof

The problem: Visitors do not know you. Without customer reviews, portfolio photos, or partner logos, they have no reason to trust you.

The solution: Add real customer testimonials, before/after photos, and numbers ("+200 satisfied customers," "4.8/5 on Google"). Social proof converts.

Mistake 9: Hidden Contact Information

The problem: The visitor wants to call you but has to search for your number for 3 minutes. They give up and call your competitor instead.

The solution: Phone, WhatsApp, address, and email visible from the homepage. In the header and in the footer.

Mistake 10: No Updates

The problem: A site with "Christmas 2024 promotions" in April 2026 is a signal of abandonment. Visitors wonder if you are still in business.

The solution: Update your site regularly. An active blog shows you are alive and relevant. At Kolonell, we offer maintenance packages starting at 25,000 FCFA/month.

How to Know If Your Site Has These Problems

Take this quick 5-minute test:

  • Open your site on your phone — is it readable and fast?
  • Search for your business on Google — do you appear on the first page?
  • Ask a friend to find your phone number — can they find it in under 10 seconds?
  • Look at your last published content — is it more than 3 months old?
  • Do you have a visible WhatsApp button?

If you answered "no" to more than 2 questions, your site needs a redesign.
