Thanks for starting this discussion on pop-up performance. I’ve recently worked on optimizing pop-ups for a mobile gaming blog (focused on Cricket mobile games) and found a few key takeaways:
Timing matters: Showing a pop-up too early reduces engagement and annoys users.
Relevance: Pop-ups that match user intent (e.g., “Download safe version” for a gaming site) perform better.
Performance cost: Large pop-up scripts/cookie banners can significantly slow page load — use async loading or defer scripts.
A/B testing: Try different triggers (scroll percentage, exit intent) and track conversion + bounce rate.
Would love to hear if others have measured how much performance load pop-ups add (e.g., in ms) and what threshold they consider acceptable.
