Biggest movers

Sites whose performance score improved by more than this group's normal run-to-run noise. Everything else is jitter and is deliberately hidden.

Leaderboard

Ranked by the circle color first: all green beats a row with amber, which beats red. Sites are not penalized for unknown Core Web Vitals. Tiebreakers include: sum of all four Lighthouse categories, fewest failing Core Web Vitals, then fewest axe violations, then Speed Index per KB — a heavy site outranks an empty one.
