How do I handle third-party scripts that slow down performance?

Third-party scripts such as analytics, chat widgets, marketing pixels and social media embeds are among the most common performance bottlenecks. We proceed in three steps: First, we inventory all included third-party scripts and assess their business value. Second, we eliminate scripts that are no longer needed. Third, we optimize the remaining ones through delayed loading (lazy loading after user interaction), self-hosting script files on your own server, facades for chat widgets and embeds, and service workers for targeted caching.
