How can I reduce third-party script impact on page load times?

Asked on Dec 12, 2025

Answer

Reducing the impact of third-party scripts on page load times involves optimizing how and when these scripts are loaded to minimize their effect on performance metrics like LCP and FID.

Example Concept: To mitigate the impact of third-party scripts, consider using async or defer attributes to load scripts without blocking rendering. Additionally, use resource hints like preconnect to establish early connections, and consider lazy loading scripts that are not immediately necessary for the initial page load.

Additional Comment:

Identify critical scripts and load them asynchronously to prevent blocking the main thread.
Use the "defer" attribute for scripts that don't need to execute until after the document has been parsed.
Consider splitting third-party scripts and loading only the essential parts initially.
Monitor and audit third-party scripts regularly to ensure they are still necessary and optimized.
Use a content delivery network (CDN) to serve third-party scripts closer to your users.
