What is the conversion lift when I show a progress bar to free shipping?

I'm exploring ways to increase my e-commerce store's conversion rate and average order value. I've heard that free shipping progress bars can motivate customers to add more items to their cart, but I want concrete data on the potential impact. How much can a strategically designed shipping progress bar actually increase conversions, and what psychological principles make it effective? I need evidence-based insights to justify implementing this feature and understand its potential revenue implications.

TL;DR - Quick Answer

Run push notifications for time-sensitive offers only: flash sale announcements, back-in-stock alerts, and order updates. Promotional push notifications unrelated to customer actions achieve 4-8% click rates - much better than email, but lower than SMS. Unsolicited promotional pushes erode opt-in retention.

Browser and Mobile Push Notifications: Strategy and Best Practices

Push notifications occupy a unique position in the e-commerce communication stack: they appear on the customer's screen without requiring email open behavior, but they require opt-in consent and are competed for by every app on the customer's phone. Done right, they're a high-attention channel. Done wrong, they drive opt-outs that permanently remove customers from the channel.

Push Notification Best Practices

High-Value Uses

  • - Back-in-stock for wishlisted items
  • - Flash sale with specific end time
  • - Shipping and delivery updates
  • - Price drop on a saved product

Avoid

  • - Weekly promotional pushes
  • - Non-personalized product recommendations

Push + Growth Suite timing: If you use push notifications to drive return visits for flash sales or offers, Growth Suite's Trigger Campaigns can recognize return visitors arriving via push and show a tailored on-site experience - confirming the offer stated in the push notification without requiring the visitor to search for it. This on-site follow-through is critical for push notification conversion: the promise in the push must be immediately visible on arrival.
