Robin Image Optimizer – Unlimited Image Optimization, WebP & AVIF

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

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

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 · 50% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Modeled within the band wp.org reports; tightens as we track daily.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. The recent download trend is too spiky to read.

   I am using Robin Image Optimizer along with super page cache pro. Really like the features it provides for the pricing.

   The best plugin for image optimization. But after the latest update, there’s a delay when converting Image Features to webp. Although it might just be my feeling. BTW, thanks.

   Your “fix” lasted for about three minutes. I have since then waited to give you time to migrate your servers. I have uninstalled and reinstalled the plugin several times. I have tried to get it to optimise the images about 1000 times. It keeps stopping and throwing up errors. I have wasted hours and days trying to get this thing to work. It’s infuriating!! All this is because you are selling a pro upgrade for a plugin that isn’t currently working, showing a complete disregard for other people.
