What this does not say

This ranks how production-ready each product's public surface is — not how well it does its job. For seo audit tool, that means it does not measure the quality of the work itself. Products whose sites block automated readers are left out rather than ranked last — we did not measure them, and bottom placement would claim something we never observed. Scores are floors: anything set at a CDN, a proxy or behind a login is invisible from the public surface.
