OptiExperts (Shopify Agency)

Based in London, this small team specialises in Shopify and Shopify Plus, working with ecommerce businesses in sectors such as fashion, food, apparel and health. The agency positions itself around performance-driven store design, aiming to help brands scale their online sales through tailored, conversion-focused Shopify builds. Portfolio examples mentioned include Aromely, Chatelier, Lineargent and Unimaginable Foods, all delivered as Shopify design and development projects. Services cover Shopify Plus upgrades and migrations, bespoke Shopify store development, theme customisation, and private Shopify app development, alongside store migration and replatforming work. Conversion rate optimisation is a core offering, using competitor analysis, web analytics and A/B testing to refine site content, evaluate channels such as Google Search and social media, and improve conversion rates and average order value against industry benchmarks. Speed optimisation is also provided as a distinct service, aimed at reducing load times to support navigation, user experience and rankings. Additional offerings include ongoing support and maintenance, subscription integration for stores, and two proprietary apps — ConvertIQ for AI-driven product bundles and ConvertIQ for AI product quizzes. The agency also offers a free speed audit as an entry point for prospective clients, and describes its process as starting with an initial consultation, followed by a proposal, a team introduction, and implementation focused on improving conversions.
