Test run byDRIP AgencyCRO agency
Commentary byLiftArchiveOur analysis, not theirsAdding a short emotional line under the Add to Cart button lifted average revenue per user by 3% for SendAFriend, a plush-animal gifting brand.
DRIP Agency ran the test and published it as a case study.
The line tied the click to why people buy: making someone feel comforted and loved.
- Average revenue per user: +3% against the plain button.
- The test ran only on product pages for items in stock.
- Significance and sample size were not shared, so treat the size of the lift with care.
The change
The variant adds a short emotional line right under the Add to Cart button.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
In-stock product pages showed a plain Add to Cart button with no extra text around it.
Variant
A short emotional subline sat directly under the Add to Cart button. It reminded shoppers the gift would help the recipient feel comforted and loved.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Gift buyers are buying a feeling for someone else. Naming that feeling at the click may keep the emotion going past the point where the page turns transactional.
- Much of SendAFriend's traffic comes from social media. These visitors arrive with emotion but little patience, so a quick reminder of the payoff may help them act.
- The subline is small and sits right at the decision point, so it adds reassurance without pushing the button down or cluttering the page.
Caveats: Only in-stock product pages were included. DRIP Agency did not share significance, sample size or test length.

How to run this test on your store
- Hypothesis
- If we add a short line under Add to Cart naming the emotional payoff for the recipient, then revenue per user will rise because gift buyers are reminded why they are buying at the moment they decide.
- Primary metric
- Average revenue per user
- Guardrails
- Add-to-cart rate
- Average order value
- Product page bounce rate
- Who should test it
- Gift brands and stores where people buy for someone else or for an emotional reason. It is less likely to matter for practical, spec-driven products where the buyer cares about features, not feelings.
Questions
Does text under the Add to Cart button help conversions?
It can. In this test a short emotional line under the button lifted revenue per user by 3%.
Keep it to one short line so the button stays the focus.
What should microcopy under a buy button say?
It should answer the shopper's main reason to buy or main worry.
For gifts, that is how the recipient will feel.
For other products, it might be delivery, returns or a key benefit.
Why measure revenue per user instead of conversion rate?
Revenue per user captures both how many people buy and how much they spend.
A change can lift orders but cut basket size, and this metric catches that.
