Your questions, answered
We believe in clear answers, no jargon, and total transparency — here’s what to know before we launch your CRO roadmap.
A CRO agency improves website performance through a combination of research, experimentation, and implementation. This typically includes:
- Analysing user behaviour, funnels, and drop-off points using analytics and session data.
- Conducting qualitative research such as UX reviews, customer insights, and user testing.
- Identifying and prioritising conversion opportunities with the highest revenue impact.
- Designing and building experiments (A/B tests or controlled rollouts).
- Measuring results statistically and scaling winning changes across the site.
The outcome isn’t just a higher conversion rate; it’s better user experiences and stronger commercial performance.
Yes. Step Labs covers strategy, design, and development as part of a single integrated process.
This means we don’t just recommend improvements; we design, build, test, and deploy them. From UI/UX and creative assets through to front-end and Shopify development, everything is implemented with performance and scalability in mind.
Both.
We regularly work on full website builds and rebuilds, as well as optimising existing sites. Whether it’s a Shopify store, a custom ecommerce experience, or a content-driven site, we design and build with conversion performance baked in from day one, not added later.
Yes. We work on web applications, custom flows, and product-led experiences, not just marketing pages.
Our approach applies CRO and UX principles to SaaS platforms, tools, and internal or customer-facing web apps. This helps teams improve activation, retention, usability, and monetisation across complex journeys.
Step Labs goes beyond traditional CRO to support end-to-end performance optimisation across channels and platforms.
Alongside website experimentation, design, and development, we also work on:
- Amazon optimisation, including PDP structure, imagery, copy, and conversion drivers.
- Generative Engine Optimisation (GEO), ensuring brands are accurately represented and surfaced within AI-driven search and recommendation engines.
- Creative design for performance, such as landing pages, PDPs, site visuals, and messaging systems that support paid media, without managing ad spend.
All of this work is underpinned by a data-driven, analytical approach. We use tools like Microsoft Clarity for heatmaps, session recordings, and behavioural insights, alongside advanced analytics, customer data, and leading A/B testing platforms to validate decisions and measure impact.
We’re also experienced working within modern ecommerce and product stacks, with strong partnerships across Shopify and best-in-class apps, allowing us to move quickly without compromising technical quality.
In short, Step Labs acts as a single performance partner, combining strategy, design, development, experimentation, and emerging optimisation disciplines to drive measurable growth.
CRO improves the efficiency of every other marketing channel you run.
When conversion rates increase, the same ad spend, SEO traffic, and email traffic generate more revenue without increasing acquisition costs. This often makes CRO one of the highest-ROI growth investments a business can make, especially for ecommerce brands.
In practical terms:
Traffic × Conversion Rate × AOV = Revenue
Improving any of these through CRO compounds growth across your entire funnel.
Many agencies treat CRO as isolated A/B testing. We don’t.
Our approach combines deep UX insight, commercial prioritisation, and disciplined experimentation, with a clear focus on revenue impact rather than surface-level wins.
We prioritise changes that move core business metrics, such as conversion rate, AOV, LTV, and profit, not vanity uplifts.
CRO is treated as an ongoing system, not a series of disconnected tests.
This depends on factors such as traffic volume, conversion maturity, and technical setup. However, most structured CRO programmes begin delivering measurable performance improvements within the first 8–12 weeks.
Early wins often come from high-impact areas like PDPs, carts, checkout flows, and offer presentation, while longer-term gains compound as insights build over time.
Yes. We regularly work alongside in-house teams, developers, designers, and paid media agencies.
This collaborative model often produces the strongest results, as CRO insights feed directly into product decisions, creative strategy, and acquisition performance. We integrate into existing workflows rather than replacing them.
