summary: "Honest deadlines (launch close, price-increase date, cohort start) lift conversion 15% to 30%. Fake evergreen timers that reset per visitor work short-term but damage trust when visitors notice and underperform real urgency. The lift comes from the honest deadline itself, not from the timer widget – the widget just makes the deadline visible."

# Should I use a countdown timer on my sales page?

> Honest deadlines (launch close, price-increase date, cohort start) lift conversion 15% to 30%. Fake evergreen timers that reset per visitor work short-term but damage trust when visitors notice and underperform real urgency. The lift comes from the honest deadline itself, not from the timer widget – the widget just makes the deadline visible.

## Supporting points

- Real deadlines compound: each honest deadline reinforces trust for the next launch. Each fake deadline burns trust permanently.
- Cart-close emails on the deadline day move 30 to 50% of the cart's eventual revenue. The timer's job is to make the cart-close email feel earned.
- If you don't have a real deadline, manufacture one honestly: 'first 50 customers' or 'closing for the cohort start'. Don't fabricate scarcity that doesn't exist.

## Related terms

- [Offer](https://unlocksaas.com/glossary/offer) – What the page asks for and what it gives in return, structured so the perceived value is unambiguously higher than the price.
- [Weak Belief](https://unlocksaas.com/glossary/weak-belief) – One of three diagnostic labels: the person and the offer are fine but the page does not make the reader believe it will work for them.
