eCommerce Site Optimisation for Performance and Growth

Having an eCommerce site live is just the start. If performance is patchy, conversion is low or the customer journey feels clunky, it’s costing you growth every day. At STRATAGEMS, we help you get more from the platform you’ve already invested in through targeted improvements to speed, UX, architecture and flow. We bring 25+ years of hands-on experience optimising eCommerce sites across platforms, markets and business models. Whether it’s removing friction in the buying journey, increasing mobile performance or improving back-end stability, we focus on what drives results and not just what’s easy to measure.

We help retailers get more from their existing eCommerce platforms by identifying and implementing targeted improvements that enhance performance, usability and commercial impact. Our work delivers tangible results from faster load times, smoother customer journeys, higher conversions to stronger long-term scalability.

‍UX and conversion analysis: We review customer journeys, search behaviour, checkout flow and navigation to surface friction points and lost opportunities and then provide clear, prioritised fixes.
‍Performance and speed tuning: We diagnose front-end and server-side issues that slow your site down, especially on mobile. Our optimisation work improves speed, Core Web Vitals and perceived responsiveness.
‍Technical architecture review: We assess how your eCommerce stack is wired from middleware and APIs to integrations and hosting to identify bottlenecks, fragility and scalability limits.
‍Mobile and international readiness: We ensure your site delivers a fast, consistent experience across devices and geographies, addressing localisation, currency handling and mobile-first usability.
‍Search, merchandising and discovery: We improve how customers find and engage with products including tuning on-site search, optimising filtering, and aligning product data structures with business priorities.
‍Actionable prioritisation: We provide a clear set of prioritised recommendations and can help you deliver them, working alongside your internal team or agency.

Our optimisation process is designed to uncover the most impactful opportunities for improvement and guide your team in implementing them efficiently, collaboratively and with measurable results.

‍Initial discovery and performance review: We begin with a focused review of your current site, analytics and customer journey. This includes technical performance, UX flow, conversion data and operational pain points aligned to your commercial goals.
‍Opportunity identification: We map out where the biggest gains can be made from speed and mobile performance to checkout efficiency, on-site search, merchandising, and backend architecture.‍
Prioritised recommendations: You receive a clear, ranked set of improvement areas. Each recommendation includes rationale, estimated impact, expected ROI and suggested implementation approach.‍
Collaborative action planning: We align with your internal team, agency or platform partner to plan how improvements will be delivered balancing quick wins with strategic fixes.‍
Optional implementation support: We can remain involved to help oversee changes, support delivery, validate improvements and ensure changes result in real-world performance gains.‍
Review and evolve: Optimisation is never a one off exercise. We review progress, re-evaluate priorities and help you build the muscle to continue improving over time.

eCommerce optimisation isn’t just about tweaking settings - it’s about understanding the entire customer journey, the systems behind it, and the commercial pressures driving growth. At STRATAGEMS, we bring decades of experience delivering full-scale eCommerce solutions across multiple verticals from mid-sized retailers to global enterprise brands.

‍Proven across industries: We’ve delivered results in fashion, beauty, health, telco, grocery, travel and beyond. That breadth of experience means we bring relevant insight to your specific context whether you're B2C, B2B or hybrid.‍
Mid-market to enterprise scale: We understand the realities of complex operational models, cross-channel strategies and ambitious growth targets. We’re used to working with internal teams, multiple vendors and global technology stacks.
‍More than front-end fixes: Our approach goes beyond UI tweaks. We optimise across architecture, integrations, search, merchandising, mobile and performance bringing improvements that are measurable and meaningful.‍
Experience-led recommendations: Our advice is grounded in real-world delivery, not just analysis. We know what works, what scales and what to prioritise when resources are limited.
‍Clear delivery support: Whether you need help executing changes or aligning your existing teams, we stay hands-on guiding improvements from recommendation through to impact.
