Showing an Estimated Dispatch Time on a Product Page

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.

Purchase conversion rate (CR)

Compare purchases per assigned visitor who meets the same dispatch-estimate rule.

• Add-to-cart rateCheck whether shoppers take the first purchase step.
• Order completion rateReview completed orders among checkout starters alongside overall purchase conversion.
• Return rateTrack returns over the same follow-up period; do not attribute every return to delivery timing.
• Shipping-related support contactsWhere possible, track questions about dispatch and arrival separately.

• DeviceReview the same estimate presentation on mobile and desktop.
• StageThis test covers dispatch estimates only. Label them clearly so visitors do not mistake them for delivery dates.
• CommitmentDo not present an estimate as a guarantee.
• CalculationKeep the inventory, location and order cut-off rules that generate the message fixed.
• PlacementChoose one placement near the price or CTA before launch.

1. 1More 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.
2. 2Track 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.
3. 3Keep 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.
4. 4When the result stays unclear, use the 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.
