The Shopify Speed Checklist: Six Fixes for a Slow Store
Brainwave Technologies 1 min read
Every extra second on a phone costs a store sales, and most owners never see it in their reports. These six fixes are where we start on a slow store.
The checklist
- Audit the app stack. Every Shopify app injects scripts, so remove any app that no longer earns its place.
- Replace slider heroes with a static LCP image. Sliders murder LCP and nobody clicks slide two.
- Compress and convert to WebP. Product galleries are usually the heaviest thing on the page.
- Lazy-load below the fold, including reviews widgets and Instagram feeds.
- Preload the hero image, font subset and critical CSS.
- Defer every third-party pixel until after first paint.
Measure what matters
Track LCP, CLS and INP in Search Console's Core Web Vitals report. Lab scores lie; field data pays. Re-test after every app install; speed regressions arrive silently.
Speed work is unglamorous, but it compounds: better ads Quality Score, better SEO, better conversion, all from the same fix.
