# Storefront Lab HQ - Experiments and CRO for Shopify storefronts

Source: https://storefrontlabhq.com/

A working lab for Shopify conversion experiments and storefront testing.

* [What should you test first on a low-traffic Shopify store?](https://storefrontlabhq.com/blog/shopify-low-traffic-testing-priority/index.md)

  Low-traffic stores cannot run textbook A/B tests: the math never converges. Test big, obvious things instead, and use methods that do not need statistics.
* [Does an A/B test anti-flicker snippet slow your Shopify store?](https://storefrontlabhq.com/shopify-anti-flicker-snippet-lcp/index.md)

  Often, yes. It hides the page until the test script loads, so nothing paints. Shopify lists removing anti-flicker snippets as a performance step.
* [Measure a Shopify script before removing it](https://storefrontlabhq.com/measure-shopify-script-cost/index.md)

  Record load time and interaction delay on the same page and device, disable one script in a theme copy, then run the test again. One change gives you a useful answer.
* [How do you run a Shopify performance experiment without fooling yourself?](https://storefrontlabhq.com/shopify-performance-experiment-method/index.md)

  Record a baseline, change one suspected cause on a theme copy, repeat the same template and device test, and confirm both lab metrics and the customer journey before publishing.
* [Test Shopify performance template by template](https://storefrontlabhq.com/shopify-performance-test-template-by-template/index.md)

  Measure the home, product, collection, and cart templates separately. Each loads different images, Liquid, apps, and interaction code, so a single homepage score can hide the real bottleneck.
* [Shopify Core Web Vitals: LCP, INP, and CLS Explained](https://storefrontlabhq.com/shopify-lcp-inp-cls-guide/index.md)

  For Shopify storefronts, LCP shows how quickly the main content appears, INP reflects interaction responsiveness, and CLS measures visual stability. Review these metrics per template because the home, product, and collection pages have different bottlenecks.
* [How to A/B Test a Shopify Store Without a Data Team](https://storefrontlabhq.com/shopify-ab-testing-guide/index.md)

  A/B testing on Shopify means showing half your visitors a variant (a different price, layout, or copy) and measuring conversion against the original. Small stor

* [Heatmap Tools for Shopify: What They Show and How to Choose](https://storefrontlabhq.com/shopify-heatmap-tools/index.md)

* [Best Shopify product image sizes, tested](https://storefrontlabhq.com/best-shopify-product-image-sizes/index.md)

  Use square images at 2048 by 2048 pixels for product photos. That size fills Shopify's maximum zoom, stays under sensible file weights when compressed, and matc
