Shopify Speed Optimisation Checklist (UAE): Core Web Vitals
Shopify Speed Optimisation Checklist (UAE): Core Web Vitals
Faster pages convert better. Use this practical checklist to improve LCP, INP, and CLS on Shopify without breaking your theme.
Checklist
-
Media: serve WEBP/AVIF, proper dimensions, lazy-load below the fold.
-
Hero LCP: inline critical CSS, compress hero, avoid slider carousels.
-
Apps: remove unused; prefer native theme features; load 3rd-party scripts async/defer.
-
Fonts: system stack or font-display: swap; subset; preconnect.
-
JS: avoid heavy libraries; ship only what the page needs.
-
Theme hygiene: minimise DOM depth; avoid render-blocking snippets.
-
Images in PDP: use srcset/sizes; defer non-critical thumbnails.

FAQs
Will these changes break the design?
Most wins come from media, app/script governance, and CSS/JS order—design stays intact.
How fast can we see improvements?
Lighthouse improves immediately; field data (CWV) updates after Google recrawls.
Do we need a new theme?
Not always. Dawn OS 2.0 is a good base, but many themes can be tuned first.
What about international markets?
Use a CDN close to users (Shopify CDN covers this) and compress images per locale.
Will removing apps affect tracking?
We replace heavy app features with native ones and keep GA4/pixels intact.
