Shopify Speed Optimization

Overview

Eric Javits, a luxury fashion brand known for its elegant hats and accessories, sought our expertise to improve site speed on their US Shopify store. This case study demonstrates how we enhanced their website performance through targeted optimization, achieving measurable improvements in speed and user experience.

The Challenges

  1. 1. Slow Loading Times

    Pages like the homepage, product page, and collection page were suffering from high load times, affecting user experience and conversion rates.

  2. 2. Complexity of Custom Functions

    The site used multiple apps and custom functions, which needed to be streamlined without sacrificing functionality.

  3. 3. Page Speed Metrics

    Key metrics such as First Contentful Paint (FCP), Speed Index, Largest Contentful Paint (LCP), and Total Blocking Time (TBT) required significant improvement to align with Core Web Vitals standards.

the process

Eric Javits engaged EcomExperts to conduct a site speed optimization for their Shopify store. Our team performed a comprehensive audit, identifying all installed apps and custom code impacting load times. We developed a custom solution to replace unnecessary apps, optimized images, minified JavaScript, and reduced CSS, all while maintaining the site's design integrity and functionality.

To measure our impact, we conducted before-and-after speed tests using Google PageSpeed Insights, recording notable improvements across the homepage, product page, and collection page. Each page’s metrics were analyzed to ensure optimal load performance on both mobile and desktop.

the solution

  • App Reduction: We removed redundant apps that were slowing down the site and consolidated functions to decrease load time.
  • Custom Code Optimization: Our team optimized the custom code, reducing the number of requests and improving the overall page structure.
  • Enhanced Core Web Vitals: By focusing on key metrics like FCP, TTI, and TBT, we aligned the site with Core Web Vitals, enhancing its performance and user experience.
  • Speed Optimization Strategy: Implemented advanced image compression, lazy loading, and other techniques to optimize loading times, particularly on mobile devices.

results

The results were significant, with each page showing marked improvements in load times and performance metrics:

  • Homepage: Desktop score improved from 73 to 85; mobile score improved from 35 to 55.
  • Product Page: Desktop score improved from 35 to 70; mobile score improved from 31 to 49.
  • Collection Page: Desktop score improved from 35 to 68; mobile score improved from 33 to 51.

These optimizations resulted in a faster, more reliable browsing experience, allowing Eric Javits to provide an enhanced shopping experience for their customers.
