Speed affects trust and checkout
Slow stores lose users before they explore products. On mobile, every extra second can reduce trust and make checkout feel risky.
Performance work should focus on the pages that matter most: homepage, category, product detail, cart, checkout, and account login.
Start with visible bottlenecks
Large images, unused scripts, heavy sliders, poor caching, and slow database queries are common reasons stores feel sluggish.
- Compress and resize product and banner images.
- Remove unused scripts and delay non-critical JavaScript.
- Use caching for menus, category data, product lists, and CMS blocks.
- Audit checkout requests and payment callbacks.
Measure before and after
Performance should be tracked with real metrics such as Core Web Vitals, server response time, conversion rate, and checkout completion rate.
