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. This decision is saved in their browser using cookies, so it remains consistent across sessions and page reloads. To reset this value, the customer would need to clear their browser cookies. ## **Behavior in Preview Mode** When previewing Upcart in the Cart Editor, you can choose between: * **Active preview**: Shows the store as if Upcart is enabled for the visitor * **Inactive preview**: Shows the store as if Upcart is disabled This helps you test both sides of the allocation setup before going live. ## **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. Image ### 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.
