Why speed is an SEO problem on Shopify

Slow mobile pages lose rankings and orders. Shopify themes, apps, and image carousels stack up until Core Web Vitals fail.

Measure first. Our store speed check runs PageSpeed on your URL before you change anything.

Fixes that move scores

Template-level changes beat one-off tweaks on a single product page.

Hero and carousel images. Compress, lazy-load, and stop loading full galleries before LCP.
App audit. Remove scripts that block render on every page.
Font and third-party load. Defer non-critical CSS and tracking where possible.
