Conversion Rate Optimisation, Landing Pages & A/B Testing
Learn how to turn more of your existing visitors into enquiries, subscribers or customers by identifying and fixing conversion barriers.
Learning outcome: diagnose a weak conversion journey, improve a landing page and run a meaningful experiment.
01. Understand the fundamentals
Tap each topic. Its explanation appears directly below the selected topic.
CRO is the process of improving the percentage of visitors who complete a defined action. That action could be making a purchase, submitting an enquiry, booking a consultation or subscribing.
1,000 people visit a service page. Twenty submit enquiries.
Why it matters: if relevant visitors are already arriving, improving the page may generate more enquiries without increasing traffic spending.
What CRO is not: changing button colours randomly, copying a competitor or assuming a design looks better means it will convert better.
A funnel shows how people move from arriving at a page to completing the desired action.
These are illustrative numbers, not industry benchmarks. They show why tracking each stage matters.
If many people leave before reading the offer, investigate relevance and the first screen. If they click but do not complete the action, investigate the form, checkout, availability, pricing or trust barriers.
A landing page is designed around a particular visitor intention and a primary action.
Headline: Get a practical digital marketing audit for your business.
Supporting text: Understand where visitors drop off and what to improve first.
Primary CTA: Request an audit.
Multiple unrelated offers, several competing buttons, vague headlines and long blocks of text before the visitor understands the value.
Practical rule: one primary conversion goal does not mean only one clickable link. It means the page's hierarchy consistently guides visitors towards the main action.
Visitors need to understand three things quickly: what is offered, why it matters and what to do next.
Communicate a specific, relevant benefit rather than a vague slogan.
Explain what the visitor receives, who it is for and any important limitations.
Use a clear action such as “Request a quotation” or “Check availability”.
Example: “Grow your business online” is broad. “Find the three biggest conversion barriers on your service page” describes a more concrete outcome, provided the service genuinely delivers it.
A persuasive CTA cannot rescue an unclear offer. Fix the promise and visitor fit before polishing the button.
Friction is anything that makes the intended action confusing, difficult, risky or unnecessarily time-consuming.
Slow loading, tiny text, broken buttons, difficult navigation or forms that do not work on mobile.
Unclear pricing, missing delivery information, vague service details or too many choices.
Unclear business identity, unsupported claims, hidden terms or no explanation of what happens after submission.
Trust improvements: use accurate contact details, explain the process, show authentic reviews where permitted, disclose terms and provide a clear privacy notice when collecting personal information.
Out-of-the-box insight: sometimes the conversion barrier is not the design. It may be an uncompetitive offer, unsuitable audience, unavailable product or an unclear business process.
Do not assume that a page working on a desktop means it works well on a phone.
Check that important information appears early, buttons are easy to tap, fields are limited to what is necessary and the page does not shift unexpectedly while loading.
Test the full journey on a real phone: open the page, understand the offer, tap the CTA, fill in the form and confirm that the success message appears.
Do not optimise only for appearance. A visually impressive mobile page can still lose conversions if the next step is confusing or broken.
Analytics helps you distinguish a plausible explanation from a demonstrated problem.
Are visitors coming from search, paid ads, email or social media?
Are visitors viewing key content and reaching the next step?
Do people interact with the primary action?
Are visitors abandoning the form or encountering errors?
Are successful enquiries, orders or bookings recorded correctly?
Use suitable analytics events, campaign tracking and actual business records. Check tracking quality before interpreting a sudden rise or fall in conversions.
Important: a correlation in analytics does not automatically prove why a visitor behaved a certain way.
An A/B test compares two versions of a page or element to learn which performs better for a defined metric.
Example hypothesis: “Making the delivery information visible near the CTA will increase completed orders because visitors can understand the total cost earlier.”
How to test:
- Define the problem using evidence.
- Write a hypothesis and choose one primary metric.
- Compare versions with a fair allocation of eligible traffic.
- Allow sufficient time and sample size for a reliable result.
- Review the result and relevant guardrail metrics before deciding.
If traffic is low, prioritise fixing obvious usability failures, gathering customer feedback and testing larger, well-reasoned improvements. An A/B test is not always the best first step.
The metric must match the business goal.
Qualified enquiries divided by eligible visitors, if that is your defined success metric.
Completed purchases divided by eligible sessions or visitors, consistently defined.
Confirmed bookings divided by the relevant visitor group.
Also monitor lead quality, order value, cancellations, refunds, cost per acquisition and revenue. A page that generates more low-quality leads may be worse for the business.
Key distinction: more clicks are not necessarily more customers, and more conversions are not necessarily more profit.

06. Final business challenge
A business gets 5,000 monthly landing-page visitors but only 25 qualified enquiries. The team suggests doubling the ad budget.
Step 1: Calculate the baseline. Twenty-five qualified enquiries divided by 5,000 visitors gives a 0.5% qualified-enquiry rate, assuming those figures use the same period and denominator.
Step 2: Validate tracking. Confirm that all qualified enquiries are recorded and that duplicate or irrelevant leads are handled consistently.
Step 3: Diagnose the source and funnel. Compare traffic quality, landing-page engagement, CTA clicks and form completions.
Step 4: Investigate the offer. Check whether the page explains the service, pricing or process clearly and attracts the right audience.
Step 5: Prioritise the biggest evidence-backed barrier. Fix broken forms or confusing information before running sophisticated experiments.
Step 6: Measure qualified enquiries and economics. Do not celebrate more raw leads if the cost per qualified lead or sales quality worsens.
