Common causes
These are the issues we find most often when auditing slow stores:
- Too many apps injecting scripts on every page
- Leftover code from apps that were uninstalled
- Uncompressed, oversized images and autoplaying videos
- Outdated or heavily customised themes
- Multiple tracking pixels and chat widgets loading at once
How to measure
Use Shopify's Web Performance report and Google PageSpeed Insights on your homepage, a collection page and a product page. Focus on Largest Contentful Paint (LCP), Interaction to Next Paint (INP) and Cumulative Layout Shift (CLS).
Fixes that make a difference
Audit your apps and remove anything you don't actively use, then check the theme code for leftover snippets. Serve images at the size they're displayed and let Shopify deliver modern formats. Lazy-load images below the fold. Move to a modern Online Store 2.0 theme if yours is several years old.
Frequently asked questions
Does store speed affect Google rankings?
Yes. Page experience, including Core Web Vitals, is one of the signals Google uses, and faster stores also convert better.
Will removing an app delete its code?
Not always. Some apps leave snippets in your theme that need to be removed manually.
