Conversion Rate Optimisation (CRO) – Getting more results from your existing visitors

‍

Introduction

Your website gets a decent number of visitors, but… they don't do anything. They don't click, don't call, don't buy, and certainly don't fill in a form. Sound familiar? Then you're definitely not the only one. Many business owners invest time and money in a beautiful website – but perhaps forget the most important thing: conversion.

Put simply, conversion means: a visitor does what you want them to do. That could be a purchase, but also an enquiry, a sign-up or a phone call. And the more visitors convert, the more results you get – without needing more visitors.

In this extensive, easy-to-understand article, we'll take you into the world of conversion rate optimisation. No technical tricks, just clear explanations, smart insights and practical steps. Because whether you run a webshop, offer a service, or want people to sign up for your newsletter: you want your website to work for your business.

1. Why conversion is so important

Imagine you have a physical shop. Every day, 100 people walk in, but nobody buys anything, asks a question, or looks beyond the shop window. You wouldn't accept that, would you?

Yet this happens online all the time. Websites attract visitors but fail to convince them to do anything. That's a shame. Because improving your conversion rate – for example from 1% to 2% – means you suddenly get twice as many customers from the same number of visitors.

2. Start with insight: how is your site performing now?

You can only improve once you know where you stand. Ask yourself:

• How many people visit your website?
• Where do they land (which page)?
• How long do they stay?
• When do they drop off?

Use tools such as:

• Google Analytics: shows how many visitors you have, where they come from and which pages they visit.
• Microsoft Clarity or Hotjar: literally show where people click, scroll and drop off. It's like looking over their shoulder.

Look at your key pages – such as your homepage, contact page or product page – and analyse:

• Is the message immediately clear?
• Is the call-to-action button clearly visible?
• Is there anything that distracts or confuses?

3. Clarity above all: is your value proposition clear?

Visitors decide within 5 seconds whether to stay or click away. That's why it must be immediately clear:

• What do you offer?
• Who is it for?
• What does it deliver?

Tips:

• Put your key message at the top of the page
• Use a strong, simple heading (e.g. "The bike shop for sporty e-bikes in Utrecht")
• State your benefits, not just your features ("Delivered within 24 hours" is stronger than "Fast service")

4. Calls-to-action (CTAs): steer your visitors in the right direction

Many websites make the mistake of trying to do everything at once: buy, call, newsletter, follow on social media, request a quote… The result: the visitor does nothing.

Make sure there's one clear action per page. And make it appealing:

• Use active words: "Request a quote" instead of "Submit form"
• Show what it delivers: "Free introductory chat" works better than "Sign up"
• Make your button stand out in colour and position

Repeat your CTA several times on a page: at the top, halfway down, and at the bottom.

5. Building trust: proof and clarity

Visitors have doubts. Can I trust this company? Will I get what I expect? What do others think?

Be transparent and show that you're reliable:

• Show customer reviews (preferably with a name, photo or star rating)
• Add quality marks or certificates
• Display your phone number and physical address clearly on your site
• Use clear photos of yourself, your team or your workplace

Also make sure your site looks professional: consistent colours, easily readable text, no odd error messages or outdated information.

6. Forms: the less hassle, the better

Nothing is as annoying as an endless form with 12 fields, 8 of which are mandatory. Keep it simple.

• Only ask for what you really need.
• Put easy fields at the top (such as name and email)
• Use multiple steps if the form has to be longer (with a progress bar)
• Give visual feedback: checkmarks, error messages, success signals

Bonus: try testing different button text. "Submit" is boring. Try: "Yes, I want free advice!"

7. Speed and mobile: don't underestimate them

If your site is slow or doesn't work well on mobile, you'll lose visitors before they do anything. Test your site with tools such as PageSpeed Insights and Google's mobile-friendliness test.

Make sure you have:

• Fast loading times (max 2–3 seconds)
• Simple navigation, especially on mobile
• Large buttons and enough white space

8. Test, test, test (but smartly)

You don't need to build a whole new site straight away. Small changes can have a big impact.

Things you can test:

• Different colours or text for your CTA button
• A different order of your elements
• A video at the top instead of an image
• Different headings for your page

Use A/B testing tools (such as Google Optimize or VWO) to test two variants side by side. Always start with one change at a time, otherwise you won't know what made the difference.

9. Think like a visitor: what would you do?

Look at your own site as if you were a new customer. What stands out? Where do you get stuck? Where might you drop off yourself?

Also let others test it: friends, family or customers. Ask them:

• What do you understand right away?
• What is unclear?
• Would you request or buy something here? Why (not)?

Sometimes you get surprising insights – things that are obvious to you but not to your visitor.

10. Keep learning and improving

Conversion rate optimisation is not a one-off job. It's a continuous process of measuring, adjusting and measuring again. But it's also one of the most cost-effective investments you can make.

Small improvements can lead to:

• More enquiries
• More sales
• More customer satisfaction
• More revenue, without extra advertising costs

Make it a habit to test or improve something every month. Put it in your diary. Your website isn't a static brochure, but a living sales channel.

In conclusion: turn your website into a salesperson

Don't see your website as a digital brochure, but as a salesperson who works for you 24/7. And like any good salesperson, they need to be trained, refreshed and sharpened.

With the right approach, you'll get much more out of the visitors you already have. And that might just be the smartest way to grow.

So: take a critical look at your website, make one improvement, and keep optimising. The results will surprise you.
