These scripts may cost more than they're worth

  • Google Tag Manager adds 260ms and costs ~€3/month
  • consent.cookiebot.com adds 260ms and costs ~€3/month
  • www.gambleaware.org adds 238ms and costs ~€3/month
  • Unattributable adds 210ms and costs ~€2/month

100% 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.

63% of www.gambleaware.org'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.
