Internal project scale, not a Google or Yandex metric
Lighthouse is a laboratory test of one page, not field Core Web Vitals. The internal assessment compares stages of this project and is not a search-engine metric.
Limitations
- The first crawl covered 596 pages and the final crawl 509, so these were not the same URL set
- Mobile CLS remained at 0.537 and still needed work
- A real test lead was not followed from the form to its recipient
- Rankings, traffic and leads require a separate observation period
