Do timers hurt Core Web Vitals?

Question

As an e-commerce store owner focused on performance, I'm concerned about adding countdown timers to my website. I've heard they can impact page load speed and Core Web Vitals, which are critical for SEO and user experience. I want to understand the potential technical implications of implementing time-sensitive promotional elements without compromising my site's performance metrics. Are modern timer implementations truly lightweight, or do they introduce significant performance overhead?

Can Exit-Intent Conversions Be Tracked Accurately?
  Exit-intent tracking is accurate when set up correctly. The challenge is attributing purchases to exit-intent offers rather than other touchpoints. A structured tracking approach eliminates ambiguity and gives you real ROI data.

Conversion Tracking
