Conversion Rate Optimisation

What is It?
Conversion Rate Optimisation is the process of improving a website so that more visitors take meaningful action, whether that is making a purchase, submitting an enquiry, or starting a trial. But in practice, CRO is less about pushing people to convert and more about understanding why they hesitate.
Most users don’t leave because they dislike the product. They leave because something feels unclear, overwhelming, or slightly off. CRO is about identifying those friction points and fixing them in a way that feels natural and aligned with the brand. When done well, the website doesn’t feel optimised. It simply feels easier to use.
Good CRO balances logic and psychology. It considers how people scan pages, where doubts appear, what questions go unanswered, and what signals build trust at the right moment. The goal is not to manipulate behaviour, but to design an experience where the next step feels obvious.

Common Mistakes
- Chasing shortcuts and “growth hacks” instead of studying how real users behave
- Copy-pasting best practices from other websites without understanding the context behind it
- Over-optimising in a way that damages brand trust or makes the E-commerce website feel extremely desperate to sell to the customers
- Changing way too many things all at once and having no idea what actually worked in your E-commerce website’s favour
- Obsessing over CTA buttons while completely ignoring vital aspects of building an E-commerce website, like the messaging, hierarchy, and flow
Most CRO fails because it focuses on tactics instead of thinking. These mistakes usually lead to surface-level improvements that don’t sustain long-term growth.

The Suplex Way
- We start with user behaviour, not opinions. Data, recordings, and patterns guide every decision we take for the client’s E-commerce website
- We focus on clarity first. If users understand the product, pricing, and value, conversions follow
- We prioritise clarity over persuasion. When the product, pricing, and value are easy to understand, conversion improves naturally
- We make focused, intentional changes rather than redesigning everything at once
- Every change is measured so we know what improved performance and what didn’t
- We always balance optimisation with brand experience, ensuring the site feels confident, not desperate
At Suplex, CRO is treated as an ongoing improvement process, not a one-time experiment. The objective we have for any brand website’s CRO is to remove friction, build trust, and let the product sell itself.

Frequently Asked Questions
What is conversion rate optimisation really about beyond increasing sales numbers?
Users rarely drop off because they suddenly lose interest. More often, they hesitate because something feels unclear, risky, or overwhelming. It might be a value proposition that isn’t landing fast enough, missing reassurance around quality or returns, or having too many options that make choosing feel hard. Small moments of uncertainty stack up and turn intent into inaction.
Brands like Casper tackled this by simplifying product choices and reducing decision fatigue, which helped customers move forward with more confidence. At Suplex, we usually spend one to two weeks analysing where hesitation shows up and what’s causing it. If you want to pinpoint and remove the doubt in your buying journey, getting on a call with our experts at Suplex can help surface what’s really getting in the way.
Why do users hesitate or drop off even when they are interested in the product?
One of the biggest CRO mistakes brands make is testing without a reason. Random A/B tests, copying competitors, or chasing “best practices” often lead to cosmetic changes that don’t move real business metrics. Without understanding why users behave a certain way, optimisation becomes guesswork.
Companies like Booking.com succeed because they test with clear hypotheses rooted in user behaviour and data, not intuition alone. At Suplex, we usually spend one to two weeks auditing CRO issues to identify what’s genuinely hurting conversions before suggesting experiments. If you want to fix the right problems instead of running random tests, having a conversation with our experts at Suplex can help set a more effective CRO direction.
What are the most common mistakes brands make when trying to optimise conversions?
In CRO, not all changes are equal; in fact, the very first step is to weigh potential impact against effort and risk. High-traffic areas, critical steps in the funnel, and moments where users hesitate tend to offer the biggest returns. Smaller cosmetic tweaks can wait; however, the goal is to focus on changes that meaningfully affect behaviour, not just appearance.
Companies like Amazon prioritise improvements in their highest-traffic and highest-impact flows before touching edge cases. At Suplex, we usually spend about a week mapping CRO opportunities into a clear priority order, so teams know exactly where to start. If you want help zeroing in on what will actually move conversion, having a word with our experts at Suplex can help sharpen that focus.
How do you decide what to change first in a CRO process?
Improving conversions shouldn’t come at the cost of how your brand is perceived. Tactics that feel pushy, manipulative, or desperate might lift numbers in the short term, but they quietly erode trust. The better approach is to align persuasion with your brand’s tone, values, and level of confidence. When messaging feels honest and consistent, customers move forward because they want to, not because they were pressured.
Brands like Apple are a good example of this balance. Their experiences convert strongly without relying on aggressive tactics, because the product story, design, and reassurance do the heavy lifting. At Suplex, we usually spend two to three weeks working through trust-safe optimisation, making sure changes support both conversion and credibility. If you want to grow responsibly without damaging brand equity, speaking with our experts at Suplex can help shape that approach.
