Description and testimonial above the fold: +6% conversion rate
Test run byOptiMonkTesting and CRO tool
Commentary byLiftArchiveOur analysis, not theirsAdding a short product description and a customer testimonial above the fold on Vegetology's product pages lifted conversion rate by 6% and unique purchases by 10.3%.
OptiMonk's team made this change for the vegan supplements brand and published it as a case study.
The description and testimonial went in together, so the result belongs to both.
- Conversion rate: +6%.
- Unique purchases: +10.3%.
- Revenue and order value effects were not shared.
The change
Variant adds a short description and one testimonial above the fold.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
The top of the product page had no short description or testimonial. Reviews sat near the bottom of the page, where few people saw them.
Variant
A block with a short product description and one customer testimonial was added above the fold. It was added with an OptiMonk embedded content campaign.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Shoppers saw what the product does and that others liked it without scrolling.
- Supplement buyers often want reassurance from other buyers before trying a new brand.
- Strong reviews were already there but hidden low on the page, so moving proof up was an easy gain.
Caveats: The source does not say how the comparison was run, or give sample size, duration or confidence. Description and testimonial were added together, and results are vendor-reported.

How to run this test on your store
- Hypothesis
- If we add a short description and a customer testimonial above the fold on product pages, then more visitors will buy because they get the key facts and social proof without scrolling.
- Primary metric
- Product page conversion rate
- Guardrails
- Add-to-cart rate
- Revenue per visitor
- Mobile scroll depth
- Who should test it
- Stores with good reviews buried low on the product page, especially for products that need trust, like supplements or skincare. If your reviews already show near the top, expect less.
Questions
Should testimonials go above the fold on product pages?
It worked here, where reviews had been buried at the bottom.
One short quote near the buy button is enough to test.
How long should an above-the-fold product description be?
Keep it to a line or two on what the product does. The full details can stay lower down.
Can I add content to a product page without a developer?
Yes. Vegetology used an embedded content tool to place the block without changing the theme.
