Certification logos and payment icons by Add to Cart: 11.26% vs 1.48%
Commentary byLiftArchiveOur analysis, not theirsAdding a banner of payment icons and product test certification logos near the Add to Cart button lifted the Add to Cart click rate from 1.48% to 11.26%.
Manna Natural Cosmetics, a Hungarian store selling handmade organic soaps, body butters and oils, ran the test and it was published as a VWO case study.
A second version with certification logos only reached 8.73%.
- Add to Cart click rate: 1.48% on the control, 11.26% on variation 1 (certifications plus payment icons). Variation 1 was the overall winner.
- Variation 2 (certifications only) reached 8.73%. The source's headline figure of +490% refers to this version, not the winner.
- Both versions beat the control by a wide margin, which suggests the certification logos did most of the work and payment icons added more on top.
- The test measured clicks on Add to Cart, not completed orders or revenue.
The change
The winning variant adds payment icons and certification logos right by Add to Cart.

Control
The product page had no certification logos or payment icons anywhere near the Add to Cart button.
Variant
Variation 1 added a large banner near Add to Cart with a row of well-known payment icons and three product test certification logos below it. Variation 2 showed two rows of certification logos and no payment icons.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Manna is a small, lesser-known brand. Independent test certificates give shoppers proof of quality that the brand name alone could not.
- Familiar payment logos answer a second worry: whether it is safe to pay an unfamiliar store.
- Placing the reassurance right next to the button puts it in front of shoppers at the moment they decide.
- The very low control rate left a lot of room to improve, so part of the gap may be noise in a small sample.
Caveats: Just over 3,000 visitors were split across three versions, and the control's 1.48% click rate is unusually low, so treat the size of the lift with care. Only Add to Cart clicks were reported, not sales.

How to run this test on your store
- Hypothesis
- If we show third-party quality certifications and familiar payment icons next to Add to Cart, then more visitors will click Add to Cart because they will trust both the product and the checkout.
- Primary metric
- Add to Cart click rate on product pages
- Guardrails
- Checkout completion rate
- Revenue per visitor
- Page load time on mobile
- Who should test it
- Small or newer brands, especially in natural or health products, where shoppers doubt quality claims. Well-known brands with strong reputations will probably see much less.
Questions
Do trust badges near the Add to Cart button increase conversions?
They can, especially for lesser-known brands. In this test, certification logos and payment icons near the button lifted Add to Cart clicks from 1.48% to 11.26%, though on a small sample.
Which works better, certification logos or payment icons?
Here, certifications alone reached 8.73% and certifications plus payment icons reached 11.26%.
Combining proof of product quality with payment reassurance did best.
Should I measure clicks or sales when testing trust badges?
Measure both. Add to Cart clicks show early intent, but completed orders and revenue tell you whether the lift holds through checkout.
