Showing a dynamic estimated delivery date next to the add-to-cart button lifted conversion rate by 3.82% and revenue per visitor by 5.69%. Vasta ran this test for TryAuri, a supplements brand, and published it as a Vasta case study. Price, traffic and creative did not change.

## Result

**+3.82% conversion rate**

- Conversion rate: +3.82% at 95% confidence. A modest but real lift from one small element.
- Revenue per visitor: +5.69%. Revenue rose a little faster than orders.
- Vasta reports about $12,300 in added monthly revenue. This is the agency's own figure.

## Control

The product page said "Fast Shipping" but never said when an order would arrive.

## Variant

A dynamic tag beside the add-to-cart button showing the estimated delivery date, designed mobile-first.

## Why it likely won (our reading)

- A specific date answers a question shoppers have right before they commit. A vague promise leaves them to guess, and people tend to guess the worst.
- Placing the date next to the button puts the reassurance at the moment of decision rather than in a shipping policy page.
- A date can also signal that the order needs to happen soon to arrive by then, adding light urgency.

## Caveats

Vasta reports 95% confidence, but sample size and test duration were not shared. The revenue figure is reported by the agency.

## How to run this test

- Hypothesis: If we show a specific estimated delivery date next to the add-to-cart button, then conversion rate will rise because shoppers stop worrying about how long delivery will take.
- Primary metric: Conversion rate
- Guardrail: Revenue per visitor
- Guardrail: Delivery-related support tickets
- Guardrail: Late-delivery rate versus the shown date
- Who should test it: Stores that ship reliably within a predictable window and currently use vague shipping language. Skip it if your fulfilment times vary widely, because a wrong date can do more harm than no date.
