Conversion Rate Optimisation: How to Turn More Visitors Into Customers

Plenty of websites pull in visitors and still generate very few leads: the traffic looks healthy in analytics, but the enquiries and sales don’t follow. This usually points to a messaging problem, weak CTAs, or on-page friction. 

Conversion rate optimisation (CRO) is what solves these problems using techniques like behavioural analysis and A/B testing. 

However, the best approach is to think about CRO from the start when planning a website project, as it’s a lot easier to design in than bolt on later.

What is conversion rate optimisation (CRO)?

CRO is the practice of increasing the proportion of your visitors who do what you want them to, whether that’s making a purchase, filling in a form, booking a call or signing up. 

Rather than chasing more traffic, you get more value from the traffic you already have. Your conversion rate is the percentage of visitors who complete that action: conversions divided by visitors, multiplied by 100. If 1,000 people visit and 20 enquire, that’s a 2% conversion rate.

What counts as a conversion?

Not every conversion is a sale. Most sites have one primary conversion (the main goal, usually an enquiry or purchase) and several smaller ones on the way to it: downloading a guide, adding to a basket, starting a form, watching a demo, joining a mailing list. 

Tracking the smaller steps matters, because it shows you where people commit and where they drop off, which is where the real optimisation work starts.

What’s a good conversion rate?

It depends on your industry, your traffic source and what you’re asking people to do. As a rough benchmark, many websites sit around 2% to 5%, with e-commerce often at the lower end and well-targeted landing pages higher. 

Averages are useful for context, but the number that matters is your own. Aim to beat your current rate. Moving from 1.5% to 2.5% is a meaningful gain whatever the average is. 

A landing page fed by tightly targeted paid traffic should convert far better than a homepage taking broad, untargeted visits.

Why your site gets traffic but no leads

When visitors arrive and don’t act, it’s usually one of a handful of things:

• The message isn’t clear. People can’t tell what you do, who it’s for or why it’s the better choice within a few seconds, so they leave.
• Weak or buried calls to action. If the next step isn’t obvious on every page, most people won’t go hunting for it.
• Too much friction. Long forms, forced account creation and unnecessary steps quietly cost you conversions.
• Missing trust signals. Missing reviews, case studies, client logos or credentials leave visitors unsure, especially for higher-value services.
• The site is slow or awkward on mobile. Every second of load time and every clumsy tap on a phone loses people before they convert.
• The page is trying to do too much. Competing links and distractions pull attention away from the one action that matters.

Most conversion problems trace back to one or more of these, and most are fixable without touching your traffic at all. A conversion audit from a web design agency can pinpoint which of them is costing you most.

How Smith improves your conversion rate

We study how real visitors behave, form a clear hypothesis about what’s holding them back, then test the change and measure the result. Behavioural data leads that process.

Behavioural analysis

Using heatmaps and session recordings from tools like Hotjar and Mouseflow, we watch how real visitors use your site: where they click, how far they scroll, and the exact points where they hesitate or leave. Seeing genuine behaviour, rather than assuming it, shows us which changes will actually move the numbers.

Funnel analysis

We map the full journey from landing to conversion and measure drop-off at each step. That turns a vague “the site isn’t converting” into a specific, fixable bottleneck, so effort goes where it will count.

A/B testing

We compare two versions of a page or element, a headline, a call to action or a layout, and let real traffic decide which performs better. Changes go live when the evidence backs them, and we test one thing at a time so we always know what caused the lift.

Landing page optimisation

For pages fed by paid or tightly targeted traffic, we build focused landing pages with a clear visual hierarchy, benefit-led headlines and a deliberately minimal layout. One obvious next step, and nothing competing for attention. That’s the approach our Leeds web design team brings to CRO.

CRO mistakes to avoid

• Changing everything at once. If you alter ten things and the rate moves, you don’t know which one did it.
• Copying competitors. They built their page for their audience and offer, not yours, and you can’t see whether it even works.
• Chasing vanity metrics. Traffic and time on page feel good but don’t pay the bills. Track conversions and revenue.
• Ignoring mobile. Optimising the desktop view while most visitors are on a phone fixes the smaller problem.
• Over-optimising. Stripping a page back so far that it loses the information or reassurance people need to commit.
• Testing without enough traffic. Small samples produce noise, not answers. Give a test time to reach a reliable result.

If your site brings people in but doesn’t turn enough of them into enquiries or sales, conversion is where the quickest wins usually are. Talk to the team about a website built to convert.

FAQs

What’s the difference between CRO and SEO?

SEO brings more people to your site. CRO gets more of those people to act once they arrive. They work best together: traffic without conversion wastes the visits, and conversion without traffic has nothing to work with.

How long does CRO take to work?

Some fixes, such as a clearer call to action or a shorter form, can move the numbers quickly. Reliable A/B testing takes longer, because a test needs enough visitors to give a trustworthy result. It’s an ongoing process rather than a one-off task.
