The Third-Party Problem
Third-party scripts for analytics, ads, widgets, and tracking often account for 50% or more of JavaScript execution time. Each script adds network requests, CPU usage, and potential blocking.
Managing Third-Party Scripts
1
Audit Your Scripts
List all third-party scripts. Remove any that aren't providing clear value.
2
Load Asynchronously
Use async or defer attributes. Never let third-party scripts block rendering.
3
Delay Non-Essential Scripts
Load chat widgets, social buttons, and other non-critical scripts after page interaction.
4
Self-Host When Possible
Self-hosting eliminates third-party DNS lookups and connection time for critical scripts.
