wp.org search vs our merit ranking: “before image”
wp.org orders by popularity, so a plugin a host bundled onto millions of sites, or a big-brand one that's slow and mediocre, can sit at the top. Our ranking is built to answer a different question: which of these is actually worth installing. How this works →
For “before image”, we agree with wp.org on the top plugin, and our order differs from theirs on 12 of the top 20. 1 plugin is pushed down for signals wp.org ignores: errors, a host-installed base, or removal risk.
wp.org search ranks on
Install count (uncapped), the raw star average, freshness, and support. Popularity dominates, so the biggest install base usually wins regardless of how it got there.
We add
A cap on the install boost, volume-weighted ratings, and signals wp.org can't see: whether it throws errors on current PHP, whether the install base is organic or host-pushed, and its risk of being pulled.
Ranked above its merit
Before After Image shows at wp.org #5 but places #21 on merit, a gap of 16 places. Its 1K+ installs carry it up the search order; its 5.0★ average from 3 reviews, plus freshness and upkeep, place it lower on our volume-weighted scale.
Buried gem
LiteSpeed Cache places #12 on merit, 4.8★ from 2778 reviews, but shows at wp.org #22. A smaller install base keeps it further down the default search order than its quality signals alone would.
