Proof3

Based in Stafford, Proof3 is a small team (1-10 people) working with eCommerce retailers that operate on Magento (Adobe Commerce) and Shopify. Its client base includes multi-million-pound retail brands, spanning sectors such as fashion and automotive parts, and the agency positions itself around data-driven decision-making rather than assumption-led marketing. It holds Adobe Gold Certified Partner and Shopify Partner status and describes two decades of experience in experimentation-based growth work. The agency's core offering is Conversion Rate Optimisation, built on testing and analysis of user behaviour to improve conversion rates, average order value and revenue rather than simply driving more traffic. This is paired with Technical SEO, Performance Marketing (including Paid Search), Content Marketing and Email & Automation work, delivered as part of what it calls Digital Experience Optimisation projects. For clients such as Goddiva, work centred on reviewing website and user experience to lift conversion rate and AOV; for Just Kampers, the scope covered Paid Search, SEO and CRO together on an Adobe Commerce platform, with reported outcomes including increased organic clicks, recovered revenue and reduced cost per acquisition. The agency also publishes ongoing insights on topics such as AI in content creation, event tracking on Magento, and email strategy, reflecting its stated focus on measurable, evidence-based digital growth for online retailers.
