Introduction

Overview

ICRealtime, a leading provider of security and surveillance solutions, set out to improve the performance of their SuiteCommerce online store. Acknowledging that site speed and user experience are key drivers of digital success, the company aimed to deliver a faster, smoother shopping experience for its customers.

The Challenge

ICRealtime identified significant performance bottlenecks on their SuiteCommerce site, particularly in terms of page load speed and user experience. These issues posed a direct threat to conversion rates and customer satisfaction. Using tools like Google PageSpeed Insights and GTmetrix, they uncovered pain points such as high Time to First Byte (TTFB), visual instability from layout shifts, and suboptimal handling of media and scripts.

Solution

Strategy & Implementation

After a detailed technical audit, a comprehensive optimization plan was crafted, targeting specific issues highlighted by performance analytics. The goal: reduce load times, streamline the rendering process, and deliver a more seamless browsing experience.

The solution encompassed the following key improvements:

✅ CMS Streamlining: Unused content in the CMS was removed, and CMS styles were migrated into the theme files. This consolidation helped improve load efficiency and ensure consistent styling throughout the site.

✅ Improved Loading Experience: A blank screen sometimes appeared while the site was loading. This was addressed by rendering visible elements earlier, before JavaScript had fully loaded, creating the perception of a faster site and reducing user frustration.

✅ Image Optimization:

• Images were optimized to reduce layout shifts and improve visual stability across the site.

• Loading strategies were refined to prioritize visible content and enhance overall page speed.

• The use of Cloudinary was suggested to further optimize image delivery and compression, leveraging its CDN capabilities for improved speed.

✅ JavaScript Minification: Custom JavaScript extensions were minified to shrink file sizes, enhancing script execution and reducing Total Blocking Time (TBT). This also improved the Largest Contentful Paint (LCP), one of the most important Core Web Vitals.

✅ Third-Party Script Review: Recommendations were made to audit and potentially reduce the number of third-party scripts to avoid unnecessary delays in rendering.

Outcome

Results

Thanks to these focused optimizations, ICRealtime’s SuiteCommerce site experienced tangible improvements in performance metrics, including:

• Faster Largest Contentful Paint (LCP)

• Lower Cumulative Layout Shift (CLS)

• Reduced Total Blocking Time (TBT)

These enhancements translated directly into a more responsive site, better user engagement, and a stronger foundation for conversion growth.

Conclusion

By addressing performance at both the structural and visual levels, ICRealtime took a proactive approach to optimizing its SuiteCommerce experience. The project’s success highlights the power of technical refinement in driving business outcomes, delivering not just a faster website, but a better one. This investment ensures the store remains scalable, user-friendly, and aligned with the expectations of today’s digital shoppers.
