wp.org search vs our merit ranking: “images optimization”
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 “images optimization”, we agree with wp.org on the top plugin, and our order differs from theirs on 13 of the top 20. 4 plugins are 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
Image Optimizer – Compress Images and Convert to WebP or AVIF shows at wp.org #4 but places #22 on merit, a gap of 18 places. Its 1M+ installs carry it up the search order; its 1.7★ average from 81 reviews, plus freshness and upkeep, place it lower on our volume-weighted scale.
Buried gem
Converter for Media – Optimize images | Convert WebP & AVIF places #7 on merit, 4.9★ from 1106 reviews, but shows at wp.org #11. A smaller install base keeps it further down the default search order than its quality signals alone would.
