PROBLEM

The client's home decor store had a Lighthouse performance score of 34 on mobile. Large unoptimized images, render-blocking scripts, and excessive app scripts were causing page loads over 8 seconds, directly impacting their Google Shopping ad performance.

SOLUTION

I conducted a comprehensive performance audit and implemented a multi-phase optimization strategy. Replaced all product images with properly sized WebP formats using responsive srcset. Removed 4 unused apps and deferred non-critical JavaScript. Implemented critical CSS inlining, added resource hints for key third-party domains, and optimized the theme's Liquid templates to reduce server response time. Set up lazy loading for below-fold content and implemented a lightweight image zoom solution.

Project Overview

This home decor store was spending heavily on Google Shopping ads but seeing poor returns due to slow landing page speeds. Google’s landing page experience score was penalizing their ad quality score, driving up cost-per-click and reducing ad visibility.

Approach

I started with a detailed performance audit using Lighthouse, WebPageTest, and Chrome DevTools to identify every bottleneck. The optimization was implemented in priority order — tackling the highest-impact issues first. Each change was measured independently to quantify its contribution to the overall improvement.

Outcome

The transformation was dramatic. Not only did the store achieve excellent Core Web Vitals scores, but the improved performance directly translated to better Google Shopping ad performance. The client saw their cost-per-click decrease while conversion rates increased, resulting in significantly better return on ad spend.
