HTML Weight: Why 150KB Is the Budget

Above ~150KB of HTML, mobile parse time and transfer eat into your Core Web Vitals. Bloated pages usually ship inlined everything: CSS, JS, data.

How to fix it

  1. Audit raw HTML size — the grader reports yours in kilobytes.
  2. Move inline scripts/styles to cached static assets.
  3. Trim inlined JSON-LD and data blobs to what the page needs.
  4. Lazy-load below-the-fold sections instead of shipping them.
