Measure before you change
Run PageSpeed Insights on your home, collection and product pages and note mobile scores. Test on a real phone over a normal connection.
- Record LCP, CLS and INP
- Test top landing pages first
- Repeat after every change
Reduce what loads
Large images, too many apps and heavy sliders are the usual causes. Remove unused apps and leftover code from deleted ones.
- Use WebP images at the right size
- Lazy-load below-the-fold media
- Limit custom fonts
Keep it fast
Add a monthly check to your routine so new apps and banners do not slow you down again.
- Review apps quarterly
- Compress every new upload
- Watch Core Web Vitals in Search Console
