Biggest opportunity: Swap “cache” and “web vitals” for “content delivery network” and “website”. “cache” isn't earning its slot: you're not in the first 24 results for its own search. “content delivery network” sits at #6 untagged, close enough for a declared tag to move it up. “web vitals” isn't earning its slot: it only gets you to #14. “website” sits at #6 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

Install conversion
How it's measured →1.4%
of downloads still active
At least 200K of 14M lifetime downloads are still running, in line with its category: the median Performance plugin keeps 1.4%, across 1,103 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Performance plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 30 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

What to do about it
- Swap “cache” and “web vitals” for “content delivery network” and “website”. “cache” isn't earning its slot: you're not in the first 24 results for its own search. “content delivery network” sits at #6 untagged, close enough for a declared tag to move it up. “web vitals” isn't earning its slot: it only gets you to #14. “website” sits at #6 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- One page off on “web vitals”. #14 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

Après des années a avoir utilisé ce programme, je me retrouve avec des headers qui ne s’affiche pas sur certaines pages (site de 350 pages) , plus de 10 heures de recherche avec l’IA, pour enfin découvrir que c’est jetpack qui pose problème ( je travail avec WP 6.9 et maintenant 7.0 et Elementor pro et Hello ), très bon programme, mais si vous avez des problème sur votre site, désactivé Jetpack et vidé votre cache avant de chercher plus loin
