Page Speed Optimization

Page speed optimization is the technical practice of reducing the time it takes for web pages to fully load and become interactive. For e-commerce, page speed directly correlates with revenue: Amazon famously found that every 100ms of latency cost them 1% in sales. Google uses page speed as a ranking factor, and shoppers abandon slow-loading pages — 53% of mobile users leave a page that takes more than 3 seconds to load. Collection pages face unique speed challenges because they load multiple product images, dynamic content, and filtering scripts simultaneously. A collection page displaying 48 products with high-resolution images can easily become bloated without optimization. Key techniques include lazy-loading images below the fold, serving WebP format images, implementing CDN caching, minimizing JavaScript bundles, and using server-side rendering for critical content. The relationship between page speed and collection management is often overlooked. Collections with too many products per page load slowly. Collections with oversized product images consume excessive bandwidth. Collections with broken or redirected product links add unnecessary server round-trips. Maintaining clean, well-curated collections with optimized product counts is a page speed strategy in itself — fewer, better-chosen products mean faster pages.
