Asynchronous Javascript

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 · 100% 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. A small install base leaves thin data to model from.

   It worked out fine! I wanted to load my script async to increase performance and the scoring in Google PageSpeed Insights. It worked out pretty good and simple with this plugin. It still generates 1 script that doesn’t load async though. But I guess there is no simple way to integrate that inline!?

   Hi, Tested Asynchronous Javascript on our website. It lowered page speed by two points on google page speed and did not remove the javascript render blocking warning.

   I use your plugin together with the other two (WP Deferred JavaScripts and WP Fastest Cache). They all have helped to improve the page loading time tremendously well. I have mentioned all the three plugins over [Moderator note: Please don’t put links in your review] Thank you so much.

   I tried some other, but they provided more issues than they solved. This one just works. Thanks!

   This plugin is a good idea as many speed tests shows error about JS and CSS that are not asynchronous. But : – Some of my JS were broken by the plugin (Layer Slider) – Nothing is done about CSS so you still have the problem. Installing one more plugin for CSS, pfff Good luck for your work

   This plugin is amazing. It took 14 render-blocking javascript files and made them async. Didn’t even have to set anything up. Great job!!
