Estimated shipping timelines on product pages: +12.24% revenue

WinnerProduct page

Showing estimated shipping timelines, based on inventory, on product pages lifted revenue by 12.24% and CTA clicks by 4.7%.

ConvertPolo ran this test for Sparify, a motorcycle gear and parts store, on its mobile site, and it was published as a VWO case study.

+12.24% revenue
  • CTA clicks: +4.7% on mobile product pages.
  • Revenue: +12.24%. The revenue gain was larger than the click gain, which suggests more of those clicks turned into orders.
  • Both figures are reported by the agency and the testing vendor.

Simplified mockup drawn by LiftArchive from the shared screenshots.

Control

Product pages gave little sense of when an order would arrive. There was no real-time shipping information or delivery timeline.

Variant

Each product page showed an estimated shipping timeline worked out from current inventory.

Why it likely won

Our reading of the result, not the practitioner's claim.

  • Not knowing when something will arrive is a common reason to hold off. A clear timeline removes that doubt.
  • Riders often need a part or gear by a certain date. A visible estimate helps them decide on the spot.
  • Basing the estimate on live inventory makes it more believable than a generic shipping promise.

Caveats: Mobile only, and no sample size, duration or confidence level was shared. You need reliable inventory data for the estimates to be accurate.

How to run this test on your store

Hypothesis
If we show an estimated shipping timeline based on inventory on product pages, then more shoppers will add to cart and buy because they know when the order will arrive.
Primary metric
Revenue per visitor
Guardrails
  • Add-to-cart rate
  • Late delivery complaints
  • Support tickets about order status
Who should test it
Stores with stock that varies by item or warehouse, where delivery times differ. If every order ships the same day with the same timeline, a simple shipping line may do the job.

Questions

Should I show delivery dates on product pages?

It's worth testing. Sparify's revenue rose 12.24% on mobile after adding inventory-based shipping timelines to product pages.

Is an exact date better than a range?

The source doesn't say which format Sparify used.

A range is safer if your fulfillment times vary, since missed promises hurt trust.
