'Rev up your cart' cart recommendation heading: +40.37% RPV

WinnerCart

Changing the cart drawer recommendation heading from 'You May Also Like' to 'Rev up your cart' raised revenue per visitor by 40.37% for automotive parts brand PerTronix.

Blend Commerce ran the A/B test in the brand's Rebuy Smart Cart.

The result was close to, but did not reach, statistical significance.

+40.37% RPV
  • Revenue per visitor: +40.37%. This is large for a heading change, so treat it with care.
  • Average order value: +21.18%.
  • Conversion rate: +12.91%.
  • Not fully significant. Blend Commerce says results were approaching significance, and the version went live partly because it fits the brand tone.

Only the recommendation heading changes, from 'You May Also Like' to 'Rev up your cart'.

Simplified mockup drawn by LiftArchive from the shared screenshots.

Control

The recommendation section in the cart drawer used the Rebuy Smart Cart default heading, 'You May Also Like'.

Variant

The same recommendations ran under the heading 'Rev up your cart', written for car and engine enthusiasts.

Why it likely won

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

  • Default copy like 'You May Also Like' is easy to ignore because shoppers see it on many sites.
  • Copy that speaks the customer's language can make add-ons feel like part of the hobby rather than a sales pitch.
  • Part of the lift may be noise. A three-word change rarely moves revenue by 40%, so a retest would help.

Caveats: The result did not reach full statistical significance, and Blend Commerce does not share sample size or test length.

How to run this test on your store

Hypothesis
If we replace the default cart recommendation heading with copy in our customers' language, then more shoppers will add a recommended item because the section feels relevant instead of generic.
Primary metric
Revenue per visitor
Guardrails
  • Add-to-cart rate on cart recommendations
  • Average order value
  • Checkout conversion rate
Who should test it
Stores with an enthusiast or niche audience and a cart upsell still on default copy. It is cheap to test, but expect a smaller effect, and run it long enough to reach significance.

Questions

Does cart upsell heading copy matter?

It can. In this test, swapping a generic heading for on-brand copy came with a 40.37% revenue per visitor lift, though it was not fully significant.

What should I call my cart recommendations section?

Try copy that matches your customers' interests and your brand voice instead of the app default.

Test it against the default before keeping it.

Why would a small copy change move revenue so much?

Sometimes it doesn't, and a big early number shrinks over time.

Run the test to significance before trusting it.
