# Showing an Estimated Dispatch Time on a Product Page

Page: https://alidemirbas.com.tr/en/lab/ab-test-library/tests/showing-an-estimated-dispatch-time-on-a-product-page

## Hypothesis

If the product page states clearly when the order will be dispatched, visitors can decide without leaving to find out when it ships. Among assigned visitors covered by the same dispatch-estimate rule, purchase conversion rate (CR) could go up.

## When to run this test

Support requests asking when an order ships, product questions dominated by shipping timing, or visitors who check the shipping details and leave reveal that uncertainty about dispatch timing is stopping people on the product page. When the estimate helps, visitors move from cart to checkout with more confidence and shipping questions drop. Show the estimate only on products where stock and logistics data let you calculate it accurately; if that data is missing, build the calculation first rather than putting one message on every product.

## Primary metric

**Purchase conversion rate (CR)**: Compare purchases per assigned visitor who meets the same dispatch-estimate rule.

## Other metrics

- **Add-to-cart rate**: Check whether shoppers take the first purchase step.
- **Order completion rate**: Review completed orders among checkout starters alongside overall purchase conversion.
- **Return rate**: Track returns over the same follow-up period; do not attribute every return to delivery timing.
- **Shipping-related support contacts**: Where possible, track questions about dispatch and arrival separately.

## What to check before and during the test

- **Device**: Review the same estimate presentation on mobile and desktop.
- **Stage**: This test covers dispatch estimates only. Label them clearly so visitors do not mistake them for delivery dates.
- **Commitment**: Do not present an estimate as a guarantee.
- **Calculation**: Keep the inventory, location and order cut-off rules that generate the message fixed.
- **Placement**: Choose one placement near the price or CTA before launch.

## What to watch when reading the result

- More add-to-cart actions settle nothing by themselves; check whether the estimate carries through to purchase conversion per assigned visitor. Read order completion rate next to it, since a drop at checkout may mean visitors took the estimate for a delivery date.
- Track returns and dispatch- or arrival-related support contacts for the same length of time in both arms, but do not blame every return on timing expectations. If delays are possible, say so in the message; a hidden delay may lift conversion in the short term while eroding trust and skewing the result.
- Keep the carrier and the order cut-off time unchanged for the whole test; if either changes, the estimate's accuracy drifts and the early and late parts of the test no longer reflect the same conditions. If you promise guaranteed delivery, state the terms next to it, and do not present an estimate-only service as a guarantee. Treat the finding as specific to the chosen placement and the products that meet the estimate rule; look at mobile and desktop on their own.
- When the result stays unclear, use the [sample size calculator](https://alidemirbas.com.tr/en/calculators/sample-size-calculator) to check whether traffic to eligible products is enough to measure it. If it is not, run the test longer instead of loosening the estimate's accuracy to widen coverage.

## Frequently Asked Questions

### Is an estimated dispatch date the same as a delivery date?

No. This test shows when the order is expected to ship. Label it clearly and do not present an estimate as a delivery date or guarantee.

### Which products can show the estimate?

Only products for which it can be calculated accurately. Fix stock, location and cutoff rules. Do not change the carrier or cutoff time during the test.

### Can changes in returns be attributed to timing expectations?

Not automatically. Track dispatch- and arrival-related support questions separately where possible. These may show expectation mismatches more directly. Do not conceal potential delays.

### Which metric should determine the result?

Use purchases per assigned visitor eligible for the same estimation rule. Review checkout completion alongside overall conversion and examine desktop and mobile separately.
