How IndieTools Speed ranking works
This consolidated archive ranks the latest complete mobile Lighthouse observation retained for each eligible product in that ISO week. Stored scores and metrics are never fabricated or rewritten.
Performance Score ranks first. Ties are resolved by load time, LCP, CLS, TTFB and a stable identity key, in that order. Paid plans and Featured placements never affect rank.
Rankings refresh each ISO week from Monday 00:00 UTC. Finalized weekly results and awards remain permanently attached to their original evidence. This edition is marked as a legacy import in every machine-readable response.
