ShortPixel Image Optimizer – Optimize Images, Convert WebP & AVIF

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory searches this plugin turns up in, and which way each one is moving. WordPress.org publishes no history of search positions, so this starts the day we first tracked a keyword and never backfills.

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.

797 searches this plugin appeared in over the last 90 days, 20 listed. 667 left out as unrelated or noise (years, numbers, stray words).

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Crossed into this band 4.1 years ago; the previous band took 6.6 years to cross, which places it about 62% of the way through.

   I’ve used ShortPixel on several projects and it’s always a winner. For this project, I reached out to support with a query and they were excellent, courteous, fast, helpful, kind and professional. Truly a pleasure to deal with. Highly recommended.
