These scripts may cost more than they're worth

  • www.gstatic.com adds 3986ms and costs ~$53/month

  • HubSpot Analytics adds 1271ms and costs ~$17/month
  • js.hsforms.net adds 670ms and costs ~$9/month

65% of JavaScript execution time comes from third-party scripts.

Why this matters

Third-party scripts (analytics, ads, social, A/B testing) often dominate execution time — every one is a perf-and-privacy tax.

Learn more ▾

Each third-party script is a black box: you don't control when it loads, what it executes, or how much it grows. They often account for a major share of total blocking time on average sites (HTTP Archive's Web Almanac documents the trend). Audit which ones you actually need, defer the rest, and use facade patterns (lite-youtube, lite-vimeo) for embedded media.
