Like a lot of small e-commerce sites, it started out slow — product pages were taking 4-5 seconds to load on mobile, and cart abandonment was noticeably high. Here's what actually moved the needle.</p> <h2> The problem </h2> <p>Running Lighthouse on the product listing pages showed the usual suspects:</p> <ul> <li>Uncompressed, full-resolution product photos (some were 2-3MB each) being served at thumbnail size</li> <li>No lazy loading — every image on a category page loaded immediately, even ones below the fold</li> <li>Render-blocking CSS/JS from a few too many third-party scripts (reviews widget, chat widget, analytics, all loading synchronously)</li> <li>No caching headers on static assets</li> </ul> <h2> What we changed </h2> <p><strong>1. Image pipeline</strong><br> Switched to serving responsive images with srcset, converted everything to WebP with a JPEG fallback, and set explicit width/height attributes to stop layout shift. This alone dropped the average page weight by ~65%.</p> <p><strong>2. Lazy loading below the fold</strong><br> Added loading="lazy" to all non-hero images, and deferred the "you might also like" carousel until it entered the viewport.</p> <p><strong>3. Script loading order</strong><br> Moved the chat widget and reviews script to load async/defer instead of blocking render, and delayed non-critical third-party tags until after first paint using a simple intersection-based loader.</p> <p><strong>4. Caching + CDN</strong><br> Set proper Cache-Control headers on static assets and put images behind a CDN, which mattered a lot given a decent chunk of traffic comes from mobile users on slower connections.</p> <h2> Results </h2> <ul> <li>Largest Contentful Paint went from ~4.2s to ~1.8s on mobile</li> <li>Total page weight on category pages dropped by more than half</li> <li>Bounce rate on product pages improved noticeably in the following weeks (can't give exact numbers, but it was a visible shift in analytics)</li> </ul> <h2> Takeaway </h2> <p>None of this was exotic — no fancy framework rewrite, no backend overhaul. It was mostly image discipline, deferring non-critical scripts, and getting caching right. If you're maintaining a storefront for a small business, these are usually the highest-leverage, lowest-effort wins before you reach for anything bigger.</p> <p>If you want to see the current state of the site, it's live at <a href="https://wfashionlady.com" rel="noopener noreferrer">wfashionlady.com</a>.</p> <p>Happy to go deeper into any of these if people are curious — image pipeline setup, or how we handled the third-party script deferral.</p> webperf ecommerce webdev showdev
