Findings
- Component styles are shipped many times over on one page
- The one site-wide stylesheet holds far more than any page uses
- Real visitors measure a poor Core Web Vital
- The main image is lazy-loaded or not prioritised, or hidden slides load at once
- The lab run looks good but real visitors measure a worse value
- A lab metric or the page weight got worse than the earlier runs of the same page
- A page is slower or heavier than the limits in a lab run
- Lab runs of the same page differ so much that one run proves little
- A new third-party script appeared, or one changed without a change on the site
- A script or stylesheet is mostly unused on every page that loads it
