20 Cart Optimization Tactics

Reducing Abandonment

1. Show Total Cost Early

Hidden fees are the #1 abandonment cause.

Implementation:

Impact: Significantly reduces checkout abandonment

2. Offer Free Shipping Threshold

Free shipping at a threshold increases both conversion and order value.

Implementation:
