Internal project scale, not a Google or Yandex metric
CLS was reproduced in two laboratory tests of the home page. Scores 66, 72 and 76 only appear in the final report, so the page highlights the supported start and end points.
Limitations
- Performance ranged from 53 to 72 and LCP from 2.74 to 3.79 seconds between laboratory runs
- The first audit covered 606 pages and the final audit 575, so these were not the same URL set
- A real test lead was not delivered
- Rankings, traffic and leads require a separate observation period
