Should I test timer frequency?

As an e-commerce manager, I'm curious about the impact of countdown timer frequency on conversion rates. I've heard mixed advice about how often and aggressively to display urgency triggers in my online store. Some experts suggest constant reminders might create fatigue, while others argue that repeated exposure increases purchase likelihood. I want to understand the strategic approach to testing timer frequency without alienating potential customers or appearing manipulative. What methodical process can I use to determine the optimal timer display strategy for my specific audience and product offerings?
