Hire the Best Optimizely Specialists in London, UK

I have over 20 years of experience in conversion rate optimization, helping businesses increase conversions through structured analysis and data-driven A/B testing. Over my career, I've run thousands of split tests across websites and apps, testing copy, layouts, CTAs, UX elements, pricing structures, trust signals, and everything in between to systematically improve conversion rates. I've worked with a wide range of companies, from small brands to publicly traded enterprises like Trivago. I've also co-founded multiple successful businesses, including one that I scaled to 120 employees and successfully exited through an acquisition by Microsoft. Whether you're looking to increase sign-ups for your SaaS platform, reduce cart abandonment in your checkout flow, boost average order value, improve lead capture rates, or optimize conversions anywhere else, I’m confident I can help. I understand there are no “one size fits all” solutions when it comes to CRO. If we were to work together, I’d take the time to understand your needs, and goals and craft a unique plan to achieve them. That being said, I work with the majority of my clients in one of 3 capacities: Done-For-You CRO where I handle everything from the initial audit to planning the split tests and executing them in the design and development phases. I’ll run tests on copy, layout, CTAs, UX flows, pricing structures, trust signals, and other conversion elements. I’ll run anywhere from 5 to 45 tests per month depending on the type of tests we’re running and your current website traffic. CRO Audits where I analyze your website to pinpoint exactly where you’re leaking revenue and what changes will drive measurable results. You'll get a prioritized list of action items with visual examples or mockups showing exactly what to fix, so you can hand it directly to your team. My audits also come with a 1-hour implementation call so I can answer any questions you have. Hourly Consulting where I can dive into your analytics, heatmaps, and user behavior data to map out high-level testing strategies, recommend specific experiments you should run next, and answer any questions you have. Here, you can check out a few of my case studies: In 2020, I co-founded Grid, a festival ticketing and ordering platform, where I raised $5M in funding and led product management, design, and recruitment for a 15-person team. I guided the product vision, UX flow design, and conversion optimization strategy, and the platform generated $3.5M in GMV despite operating in the middle of the pandemic. In 2009, I joined Trivago as the 2nd product designer, and helped scale the company from a small startup to a $5 billion market cap with 1,500+ employees. I developed and optimized the UX for most parts of the platform, running hundreds of A/B tests on copy, design, and site architecture to systematically improve conversion rates across the customer journey. I also led the concept, prototyping, and user research for the Trivago mobile app, which became a top 10 app in Germany upon launch. In 2003, I co-founded Directshopper, a consumer electronics e-commerce business, and scaled it to €7M in annual revenue within 3 years. I led UX design, prototyping, and user research for all aspects of the website, continuously running A/B tests and optimizing the customer journey to drive more conversions. Early in my career I co-founded Ciao (acquired by Microsoft), where I raised $25M in funding and helped scale the company to a 120-employee business. I led product management and design, developing UX concepts and prototypes focused on conversion rate optimization that helped drive growth and ultimately led to the acquisition.

As a digital analytics specialist, I am looking to achieve these four objectives: ✭ Create a great user experience ✭ Maximise the number of conversions ✭ Collect and share valuable learning ✭ Contribute to the sustainable long-term growth of the business My recent achievement was migrating 9 Google accounts from UA into new GA4 properties and creating new tracking for eCommerce, conversions and events.
