Overview

Upcart includes a Traffic Allocation Percentage slider that lets you define what portion of store visitors will see the cart drawer.
  • 100% (default): All customers see Upcart.
  • 50%: Only half of customers see it.
  • 0%: Upcart is disabled for all customers.
This setting is found in Settings → Cart settings → Traffic Allocation Percent.

​
How It Works

When a customer visits your store for the first time, Upcart generates a random value to determine whether they should see the cart. The value is saved in their browser’s local storage — deliberately, so a shopper who sees the cart one day doesn’t lose it the next. Because it’s local storage rather than a cookie, clearing cookies alone won’t reset it. The customer would need to clear the site’s local storage, or use a private window.

​
Behavior in Preview Mode

Preview links from the Cart Editor and the Carts page skip traffic allocation entirely — the cart is force-enabled so you always see it, whatever your allocation percentage is set to. That means a preview can’t show you the disabled side of the split. To check what an excluded shopper sees, visit your storefront normally in a browser whose local storage hasn’t been assigned yet (a private window works).

​
How to Adjust Traffic Allocation

  1. Navigate to Settings in the Upcart Cart Editor.
  2. Use the Traffic Allocation Percent slider to set the desired percentage.
  3. Click Save to apply your changes.

Example:

  • Set to 75%: 3 out of every 4 new visitors will see Upcart.
  • Set to 0%: Useful for temporary disablement without uninstalling the app.
