Rewriting a smoked marrow bone's description to open with customers saying the bones last for hours, days or even weeks added a reported $50,945 a month in revenue. Convertibles ran this five-way test for an 8-figure dog treats brand. The duration angle beat power-chewer, excitement and anxiety angles.

## Result

**+$50,945/month**

- Revenue: +$50,945 a month for the duration angle, as reported by the agency.
- A power-chewer angle, aimed at dogs that destroy chews fast, did not beat it.
- Excitement and anxiety angles, both with an added review carousel, did not win either.
- Sample size, test length and confidence were not shared.

## Control

A generic description calling the hickory-smoked bone a long-lasting treat for all sizes that helps teeth and keeps dogs busy.

## Variant

The description opened with 'Our customers tell us their dogs chew on these bones for hours—some lasting several days or even weeks!' and then explained how the slow, low-heat smoke strengthens the bone.

## Why it likely won (our reading)

- How long a chew lasts is a question nearly every buyer has, whatever their dog.
- A concrete timeframe is easier to picture than 'long-lasting'.
- Opening with what customers report reads as more believable than a brand claim.
- Explaining the smoking process gives a reason to trust the claim.

## Caveats

The lift is agency-reported monthly revenue with no sample size, duration or confidence shared. Same product, price and page layout in every version, but two losing versions also added a review carousel.

## How to run this test

- Hypothesis: If we open the product description with the benefit customers mention most, in their own words, then more visitors will buy because the copy answers their main question with a specific claim.
- Primary metric: Revenue per visitor
- Guardrail: Conversion rate
- Guardrail: Average order value
- Guardrail: Return or complaint rate
- Who should test it: Stores with lots of reviews or survey answers that repeat one clear theme. It is less likely to help if your description is already specific, or if the product serves very different needs.
