Trustpilot review section above the fold: +2.29% revenue per visitor
Test run byDave DiederenSyntra Labs
Commentary byLiftArchiveOur analysis, not theirsAdding a dedicated Trustpilot review section above the fold raised revenue per visitor by 2.29% and conversion rate by 1.06%. Dave Diederen ran this split test for a brand with thousands of Trustpilot reviews that it was not showing on the homepage or product pages. The confidence ranges include zero, so the result is promising rather than proven.
- Revenue per visitor: +2.29% (A$4.80 to A$4.91). The tool's range was -7% to +13%, so this is not a clear win.
- Conversion rate: +1.06% (4.66% to 4.71%). Range -5% to +8%, so effectively flat.
- Average order value: +1.21% (A$102.95 to A$104.20). Also within noise.
- The testing tool estimated about A$17,800 in extra monthly revenue if the lift holds.
The change
A Trustpilot rating and review carousel added at the top of the homepage.

Control
The homepage did not show the brand's Trustpilot reviews. Visitors went from the header straight into the regular page content.
Variant
A review section was placed near the top of the page. It showed the Trustpilot rating, a short trust headline, and a carousel of customer review cards.
Why it likely won
Our reading of the result, not the practitioner's claim.
- a third-party rating answers the question of whether the store is legit before visitors start browsing.
- the brand already had a large review count, so the proof was strong and only needed to be visible.
- the small lift suggests many visitors either already trusted the brand or found reviews elsewhere.
Caveats: All three metric ranges cross zero, so the true effect could be neutral. Test duration and visitor count were not shared.

How to run this test on your store
- Hypothesis
- If we show our Trustpilot rating and review cards above the fold, then revenue per visitor will rise because new visitors will trust the store sooner.
- Primary metric
- Revenue per visitor
- Guardrails
- Conversion rate
- Bounce rate
- Average order value
- Who should test it
- Stores with a strong third-party rating and many reviews, especially those getting cold paid traffic. It is less likely to help well-known brands or stores with a weak rating.
Questions
Do Trustpilot reviews on the homepage increase sales?
In this test, revenue per visitor rose 2.29% after adding them above the fold. The range crossed zero, so the gain was likely small and not certain.
Where should I put customer reviews on my store?
This brand moved them to a dedicated section near the top of the page, where every visitor sees them. Before, they were not shown at all.
