Why website optimisation is more than just conversion rates

When we talk about website optimisation, it’s easy to default to one metric: conversion rate. It’s tangible. It’s easy to track. And yes, it’s important.

But, conversion rates are just one part of the picture.

At every stage of digital maturity, whether you’re a small retail brand just getting started, or an enterprise-level financial services firm, optimisation has a much broader role to play. It's about removing friction, strengthening decision-making, and driving long-term growth.

Let’s break that down.

1. Start with simplicity, end with strategy

Take Emily, a brand manager at a small retail business. Her goal isn’t complex, she just wants to make simple, actionable improvements on her website and have a consistent way of measuring the impact.

For her, optimisation means:

• Auditing the site to identify clear, quick wins.

• Creating a data strategy that ties to real success metrics.

• Integrating Shopify and on-site behaviour data.

• Building a dashboard to track performance.

What matters here isn't just a boost in conversions, it’s about having a reliable foundation. One where Emily can confidently experiment, report, and improve marketing outcomes without guesswork.

2. Shift from reactive to insightful

Jason, a digital marketing manager at a mid-size SaaS company, has moved beyond the basics. His focus is on understanding his customers’ pain points and shifting from reactive fixes to strategic optimisation.

That starts with:

• Creating a single source of truth for his data.

• Strengthening tech stack integrations.

• Developing a dashboard to monitor customer journeys.

• Growing his testing maturity, beyond button colours and headline swaps.

That kind of uplift isn’t possible with surface-level tweaks. It’s the result of deep insight, bold experimentation, and continuous iteration.

3. Optimisation at scale requires orchestration

At the enterprise level, optimisation is less about “what to do” and more about “how to coordinate.” Sophia, the Director of Digital Strategy for a global financial services firm, already has a fully integrated tech stack and a unified customer view.

Her challenge is actually driving predictive insights and large-scale personalisation.

To tackle this, we recommend an ‘agency village’ approach, where different internal departments, media, data science, and strategic partners work together under a shared strategy.

This collaborative model allows you to identify quarterly focus areas, design test plans, and build a backlog of ongoing optimisation opportunities, with all partners guided by the same agreed metrics, and leaning into their respective areas of specialisation to contribute to the same shared outcomes

In other words, it’s not about one test or one metric. It’s about building a culture of test, learn, adapt, across multiple teams and touchpoints.

4. It’s also about user experience and brand perception

When you measure the right performance metrics, you can spot and fix usability issues faster. And the better the usability, the stronger the engagement.

It’s all about effort versus outcome. If a change only moves the needle a tiny bit, it might not be worth it. But we always tackle the low-hanging fruit first, things like file sizes and formats, font loading, and unnecessary autoplay videos, before deciding where else to invest effort.

And remember, Google developed Core Web Vitals because they wanted a way to measure user experience. If your site is slow, cluttered, or frustrating, that affects how people feel about your brand, not just how many convert.

By running a more sophisticated A/B testing program for a financial services client, we achieved a 43% uplift in credit card application starts and a 57% increase in completions. Proof that data-backed decisions do more than just look good on a dashboard.

5. The bigger picture: Long-term value over short-term wins

Your website isn’t just a marketing tool. It’s your biggest hidden ROI driver.

Optimisation should be:

• Tied to business goals.

• Informed by data maturity.

• Prioritised based on impact and feasibility.

• Measured in terms of user satisfaction, ease of task completion, and long-term engagement, not just sales.

Hygiene, data, and user experience go hand in hand. And your optimisation journey should begin today.
