Scrolling review strip under the nav: +2.83% revenue per visitor
Test run byDave DiederenSyntra Labs
Commentary byLiftArchiveOur analysis, not theirsAdding a scrolling strip of short customer review quotes directly below the navigation bar lifted conversion rate by 2.73% and revenue per visitor by 2.83%. Dave Diederen ran this site-wide test. Average order value did not change.
- Conversion rate: +2.73% (2.31% to 2.37%). The range ran from -4% to +10%, so the lift is modest and not certain.
- Revenue per visitor: +2.83% ($1.01 to $1.03). This was the main metric, estimated at about $23,354 extra per month.
- Average order value: flat ($43.60 vs $43.64). The strip got more people to buy, not to spend more.
- Profit per visitor: not shared, because cost data was not entered.
The change
A scrolling strip of named review quotes added directly under the header.

Control
The space under the navigation bar held no social proof, so visitors went straight from the nav to the page content.
Variant
A thin strip under the nav scrolled through short review quotes, each with the customer's name and a check mark. It stayed visible without any extra scrolling.
Why it likely won
Our reading of the result, not the practitioner's claim.
- new visitors arrive without trust, and a quote from a named buyer near the top answers that early.
- the area right under the nav gets seen on every page, so proof there reaches people before they scroll away.
- motion draws the eye, while static badges tend to blend into the page after a moment.
- names and short quotes feel more human than a star average or a customer count.
Caveats: The revenue range ran from -6% to +13%, so the true effect could be near zero. Sample size and test length were not shared, and the store pictured in the post was a visual example, not the tested brand.

How to run this test on your store
- Hypothesis
- If we add a scrolling strip of named review quotes right under the navigation bar, then conversion rate will rise because new visitors see proof from real buyers before anything else.
- Primary metric
- Revenue per visitor
- Guardrails
- Average order value
- Bounce rate
- Mobile page load time
- Who should test it
- Stores with plenty of strong, short reviews and lots of cold paid traffic. It may do little if your brand is already well known, or if the strip pushes key content too far down on small screens.
Questions
What should go directly below the navigation bar?
In this test, a scrolling strip of named customer quotes in that slot lifted conversion rate by 2.73%. Many stores use that space for a shipping message instead.
Do scrolling review tickers increase order value?
Not here. Average order value stayed flat, and the gain came from more visitors buying.
Should review snippets include customer names?
This version showed a name with each quote. The idea is that a named person feels more real than a star rating alone.
