Free Shopify speed test
Paste your Shopify store URL and get a plain-English report in under a minute: which apps add weight, how your homepage performs on a phone, SEO problems that are easy to miss, and a rough idea of what slowness may cost you.
What the Shopify speed test checks
StoreScan reads the public pages a shopper sees: your homepage, a collection, a product page, the cart and the checkout entry. It adds Google's mobile PageSpeed test for the homepage, so you see real Core Web Vitals numbers next to our own findings.
- Which apps and scripts load on your pages, with measured or estimated size
- Mobile speed from Google: main content time (LCP), blocking time and layout jumps
- Duplicate product URLs, missing canonical tags and accidental noindex
- Missing meta descriptions, headings and product schema
- How long each step of the shopping path takes to load
Why Shopify stores get slow
Shopify itself is fast. Stores usually slow down because of what is added on top of the theme.
- Too many apps: every app can add its own scripts that each visitor must download, even after you stop using it
- Leftover app code in theme.liquid after an app is uninstalled
- Large hero images and sliders that delay the first view on phones
- Heavy themes with big JavaScript bundles and page-builder sections
- Chat, pop-up, review and tracking scripts that load before the page is usable
How to speed up a Shopify store
Start with the biggest wins, then test again.
- Remove apps you do not need and clean their leftover code from the theme
- Resize and compress the hero image, and do not lazy-load the first image
- Delay chat widgets and pop-ups until the visitor interacts
- Show fewer products per collection page
- Prefer lighter apps or built-in theme features where possible
Questions
Is the Shopify speed test free?
Yes. The scan, the report and the shareable link are free, with no signup.
Does the test change my store or place an order?
No. It only reads public pages and never logs in, adds to cart or submits forms.
Why is my Shopify mobile speed score low?
Mobile tests simulate a mid-range phone on a slow connection, so apps, large images and heavy scripts show up more than on a fast desktop. The report lists the biggest causes first.
Can I see which Shopify apps slow my store?
Yes. StoreScan lists the apps and scripts it recognises on your pages and marks which sizes are measured and which are estimates.
