How to read these scores
Scores are from Google PageSpeed Insights on mobile — the harder standard Google uses for Core Web Vitals rankings. Desktop scores are typically 10–20 points higher.

Why page speed matters for your Shopify store
Your choice of Shopify theme is one of the biggest factors in your store’s page speed. A well-coded theme can score 85+ on mobile PageSpeed. A bloated one might score below 50 — even with no apps installed. Start with a fast theme; it’s much harder to speed up a slow one.
How to improve your Shopify theme speed
Use compressed images
Convert product images to WebP format and compress below 200KB. Images are the #1 cause of slow Shopify stores.
Limit installed apps
Every app adds JavaScript. Audit your apps quarterly — unused apps silently slow your store.
Enable lazy loading
Most modern Shopify themes support lazy loading for below-the-fold images. Verify it's enabled in theme settings.
Avoid custom fonts
Each custom font is a blocking resource. Stick to 1–2 fonts maximum, or use system fonts for maximum speed.
Remove unused sections
Theme sections you've disabled still load their CSS/JS. Delete unused sections from your theme editor.
Use Shopify's CDN
Always serve images through Shopify's CDN (files.shopify.com) — never host them externally.
