BigCommerce Speed Optimisation

While BigCommerce manages the server infrastructure (which is very fast), your store's final speed is determined by your theme, images, and third-party apps. Large images, inefficient theme code, and numerous marketing scripts are the most common culprits that we have full control to fix.

Core Web Vitals are a set of specific metrics Google uses to measure a site's real-world user experience, focusing on loading speed, interactivity, and visual stability. They are a direct ranking factor, meaning a better score can lead to higher rankings in search results, more traffic, and more sales.

Our process is data-driven. We start with a comprehensive Performance Audit to benchmark your site and identify every issue. We then present you with a prioritized action plan. Once approved, our developers implement the technical fixes in a safe staging environment before deploying to your live store.

The most common issues we find are large, unoptimized images, an excess of third-party app scripts loading on every page, inefficient custom code within the theme, and not properly deferring non-critical JavaScript and CSS files.

No. Our goal is to make your existing site faster without altering its visual design or core functionality. All optimizations are done "under the hood." If we recommend removing an app that affects functionality, we will discuss it with you and suggest more performant alternatives.

Not necessarily. While some apps are more performance-intensive than others, our job is to find smarter ways to load them. We use advanced techniques like delaying the loading of non-essential scripts (like those for analytics or chat widgets) until after the main content is visible, so they don't impact the initial load time.

While every site is different, our clients typically see a significant improvement in their Google PageSpeed Insights scores, often moving from the "Poor" (red) or "Needs Improvement" (orange) range into the "Good" (green) range. We focus on both the score and the real-world load time.

Our service is typically 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 upfront.
