Optimus – WordPress Image Optimizer

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 · 97% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

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.

   Less work with configuration after the installation. It helps to minimize and comprimize pictures.

   The 100kb limit of the free version is very limiting and mostly serves like a demo. My disappointment was that even though i had the premium version and i optimized the images, google pagespeed still had the message that my images could be smaller.

   Pourquoi perdre du temps quand un outil peut vous en faire gagner… Si vous avez des images trop lourdes qui peuvent ralentir votre site, c’est l’outil idéal. This topic was modified 7 years, 6 months ago by Coworking à Vannes.

   A simple, fast and easy to use plugin that has great features to offer. I’ve purchased a key for the Pro version a few days ago and converted all my pictures to webP. My blog is faster than ever. If you care about your site’s speed, stop what you’re doing and purchase a key!

   ein gutes Tool, erfunden von einem der Besten -> Sergej Müller… doch nun macht das absolut keinen Sinn mehr. Warum? Hatte man mal eine HQ Lizenz und möchte diese nicht verlängern, so versagt das Plugin anschließend seinen Dienst komplett und bedient nicht mal mehr die “freien Features”.

   This one’s a gem! This is one of the plugins that helped me learn how to optimize my websites. I use KeyCDN and found a large database of articles to help optimize my websites and realized that my images were a huge problem. Once installing this baby, it was smooth sailing from there. Easy to install, and quick to shrink my images. It made a massive difference to my speed! And without much work at all! Truly made me happy to save so much time, especially when it came to my woocommerce site! Definitely glad and worth the purchase!
