Speed checklist
12 checks · 0 free · priority and impact rated
Speed is both a ranking factor and a conversion lever, and Shopify stores tend to lose it to the same handful of causes: oversized images, unused apps injecting scripts, and render-blocking third parties. These 12 checks target the specific items that move LCP and INP rather than generic "optimise your site" advice.
Every Speed check
- 1 Remove unused apps, <2.5s LCP on mobile MED
- 2 Lazy load below fold images + videos + reviews MED
- 3 Preload critical font + LCP hero image MED
- 4 Defer non-critical JS: reviews, chat until interact LOW
- 5 System font for body, Inter only for headings LOW
- 6 Limit Shopify apps <6, audit with Theme Analyzer LOW
- 7 Video <800kb, poster image, no auto HD stream LOW
- 8 Cloudflare + image CDN with WebP / AVIF auto LOW
- 9 Inline critical CSS for above-the-fold LOW
- 10 Minimize third-party scripts on checkout LOW
