What is Image Testing?

Image Testing lets you compare different visual styles of your product — such as white-background images, lifestyle shots, or model photos — to see which one drives higher engagement and conversions. Since product imagery is one of the biggest influence points in a shopper’s decision-making process, even small changes can lead to major lifts in click-through rate, add-to-cart rate, and revenue.

How does it work?

TestSignal makes image testing seamless by allowing you to assign alternate product images to different test groups. Once your test goes live, each shopper is placed into a group and consistently sees the assigned image variation everywhere the product appears — on product pages, collection pages, quick views, and cart previews.

All image updates are safely synced at the Shopify store level. No theme edits, no scripts, and no custom code. TestSignal simply swaps in the correct image source for each visitor group and tracks performance across key metrics like CTR, ATC, conversion rate, and revenue per visitor.

How can I get started?

Running your first Image test with TestSignal is super easy. To get started, you’ll need to enable the TestSignal extension in your theme. Simply go to your Shopify Online Store and click Customize, then navigate to the App Embeds section. Locate the TestSignal app toggle, turn it on, and save your changes. Once this is done, your first experiment is ready to roll!

Prefer a hands-off approach? TestSignal can handle the integration for you. Simply book a demo  with our team so we can learn about your store and get everything set up.
