Countdown timer across several brands: +9.5%, flat, and -9.2%
Ruben tested countdown timers on several brands and got opposite results: conversion rose about 10% on one, showed no clear lift on another, and fell 9% on a third. The winner sold lower-priced products that often sold out. The flat result came from a higher-priced offer after four weeks.
- Win: one screenshot shows conversion 4.15% to 4.55% (+9.53%) and revenue per visitor €1.81 to €1.99 (+9.78%). Ruben ties the near-10% win to the low-priced brand.
- Flat: the higher-priced brand showed no clear lift after four weeks of testing.
- Loss: another screenshot shows conversion 0.79% to 0.72% (-9.21%, range -17% to 0%) and revenue per visitor €0.97 to €0.89 (-8.55%, range -19% to +4%).
- The same tactic produced a win, a draw and a loss, so a single timer result says little about your store.
The change
Variant adds a countdown timer; exact placement varied by brand.

Control
Each store's normal page with no countdown timer.
Variant
The same pages with a countdown timer added. The post does not show the exact timer design or placement for each brand.
Why it likely lost
Our reading of the result, not the practitioner's claim.
- urgency works when it is real. The winning brand had sold out several times, so missing out was a real risk for shoppers.
- on a higher-priced offer, buyers take longer to decide, and a timer may not change that.
- where urgency feels fake, a timer may add pressure or doubt and push people away.
- Ruben stresses that price alone does not prove why results differed. These are explanations after the fact.
Caveats: Three separate stores with different products and prices, and visitor counts were not shared. The screenshots are not labelled by brand, so matching each to a brand relies on the post.

How to run this test on your store
- Hypothesis
- If we add a countdown timer where stock or offers genuinely run out, then conversion will rise because shoppers face a real cost to waiting.
- Primary metric
- Revenue per visitor
- Guardrails
- Conversion rate
- Average order value
- Refund or complaint rate
- Who should test it
- Stores with real scarcity, such as limited drops or products that sell out, and low-priced impulse buys. It probably won't help considered, high-priced purchases, and it can hurt where the deadline isn't real.
Questions
Do countdown timers increase conversion?
Sometimes. Across Ruben's brands, a timer lifted conversion about 10% on one, did nothing on another, and cut it 9% on a third.
When does a countdown timer work best?
In these tests it won on a lower-priced brand whose products had sold out several times, so urgency was real.
Can a countdown timer hurt sales?
Yes. On one brand conversion fell 9.21% and revenue per visitor fell 8.55% with the timer on.
