📋This is an interactive step-by-step HowTo guide with 3 verified installation steps.
The Impact of Marketing Scripts on INP and TBT
Heavy marketing tags like Google Tag Manager, Hotjar, Facebook Pixel, and live chat widgets often inject thousands of lines of unoptimized JavaScript that freezes the browser main thread during initial page render.
Nimbica Script Offloading Strategy
- Web Worker Offloading: Offload analytic event processing into background web workers using Partytown integration.
- Interaction-Based Script Delay: Defers non-essential chat widgets until the user scrolls, touches, or moves their cursor.
- DNS-Prefetch & Preconnect: Injects preconnect hints for third-party tag domains to minimize connection latency.
