Put a live countdown in the sale bar
The announcement bar carries the discount plus a live hours/minutes/seconds countdown, putting a visible deadline on the offer sitewide.
What it is
The top announcement bar pairs the headline discount with a live countdown in hours, minutes and seconds, so the offer carries a visible deadline on every page of the site.
Why it works
A deadline turns "I will think about it" into a decision now. It only works while the deadline is real: a timer that silently resets on refresh teaches repeat visitors to discount every claim the brand makes, so tie it to a genuine sale end.
How to test it
- Hypothesis
- Adding a countdown to the sale bar will lift conversion during a real promotion by putting a visible deadline on the offer.
- Primary metric
- Conversion rate (sessions during the promotion)
- Guardrail metric
- Returning-visitor conversion rate, which falls if a resetting timer erodes trust
