Swell Speed Optimisation

In virtually all cases, the performance bottlenecks are found within the custom front-end application, not the Swell back-end. Swell's infrastructure is highly optimized. Our job is to ensure the front-end we build is just as fast and efficient.

Core Web Vitals (CWV) are Google's metrics for measuring real-world user experience, focusing on loading speed, interactivity, and stability. For a modern web app, they are critical. Achieving excellent CWV scores is a primary goal of our optimization service, as it directly impacts your SEO ranking and conversion rates.

Our process is methodical. We start with a deep performance audit, using professional tools to analyze your front-end code, image delivery, API calls, and hosting configuration. Based on these findings, we create a prioritized action plan and then implement the fixes to achieve the greatest impact.

The most common issues we find are inefficient data fetching (requesting too much data from the API at once), a lack of proper caching for API responses, large unoptimized images, and large JavaScript bundles being sent to the browser.

We use a state-of-the-art, automated approach. Images are served in modern, lightweight formats like WebP or AVIF, correctly sized for every device, and delivered globally through a high-performance Content Delivery Network (CDN). This ensures images look great without slowing down the site.

No. Our optimization work is technical and happens "under the hood." We make your existing design and features faster without altering the user-facing experience, other than making it significantly quicker and more responsive.

For a headless site, the potential for improvement is huge. It is realistic to target and achieve near-perfect scores (95-100) on Google PageSpeed Insights. This translates to near-instant load times for your customers, which can have a dramatic, positive impact on your conversion rate.

This service is a fixed-price project. We begin with a paid, in-depth performance audit. The findings of that audit allow us to provide a firm, fixed-price quote for the implementation phase, so you know the full investment required to achieve your performance goals.

We offer this as a one-time project to bring your site to its peak potential. However, we also recommend an ongoing support plan. This allows us to continuously monitor performance as you add new content and features, ensuring your storefront remains lightning-fast over time.
