Should I test timer vs no timer?

I'm running an e-commerce store and have heard about the potential impact of countdown timers on conversion rates. However, I'm unsure whether implementing a timer will actually improve my sales or potentially create unnecessary pressure for customers. I want to understand the psychological effects, potential conversion lift, and best practices for testing timer effectiveness in my promotional strategies. What scientific approach can I use to determine if timers truly enhance my store's performance?
