How Orders and Sessions are Attributed

How TestSignal Attributes Orders & Sessions to Experiments

To ensure accurate and fair measurement across all experiment types, TestSignal attributes sessions and orders based on where the test is running:

• Price, Image, and Description Testing
  Total sessions = Product Sessions for the specific products selected for testing.
  Orders counted = Only orders from the products included in the test.

• Theme & Layout Testing
  Total sessions = Store Sessions, since the entire storefront experience is being tested.
  Orders counted follow standard storefront-level attribution.

• Shipping Testing
  Total sessions = Checkout Sessions, since the variation is applied during the checkout process.
  Orders counted = Only orders completed after customers see the tested shipping option.

This ensures each experiment only measures sessions and purchases influenced by the variation, providing clean, accurate, and trustworthy test results.
