wp.org search vs our merit ranking: “pdf reader”

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 “pdf reader”, we agree with wp.org on the top plugin, and our order differs from theirs on 10 of the top 20. 2 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

PDF Generator for Posts & Pages – Export Any Post Type to PDF shows at wp.org #13 but places #24 on merit, a gap of 11 places. Its 90+ installs carry it up the search order; its 1.0★ average from 1 reviews, plus freshness and upkeep, place it lower on our volume-weighted scale.

Buried gem

GiveWP – Donation Plugin and Fundraising Platform places #10 on merit, 4.6★ from 708 reviews, but shows at wp.org #21. A smaller install base keeps it further down the default search order than its quality signals alone would.

Merit ranking caps the install boost at 1M (wp.org leaves it uncapped), replaces the raw star average with a volume-weighted Bayesian score and a Wilson lower bound, and keeps wp.org's own freshness and compatibility decays.
