These scripts may cost more than they're worth

  • Google Tag Manager adds 495ms and costs ~$7/month
  • use.fontawesome.com adds 406ms and costs ~$5/month
  • Google Tag Manager adds 396ms and costs ~$5/month
  • Unattributable adds 368ms and costs ~$5/month

72% of JavaScript execution time is spent on third-party scripts. Consider auditing which scripts are essential.

Why this matters

When third-party JS execution time exceeds your own, performance gains from frontend work are capped by code you don't own.

Learn more ▾

Every millisecond of third-party JS competes with your own for main-thread time. If their share is bigger than yours, optimization on your code base barely moves the needle. Audit, defer, or remove third-parties before further frontend optimization. Use Lighthouse's third-party audit to identify the worst offenders.

72% of Google Tag Manager's code is unused. The script may be loading features you don't use.

Why this matters

Bundle has high unused-code ratio — tree-shaking and route-splitting recover the wasted bytes.
