Merge + Minify + Refresh

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. 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. A small install base leaves thin data to model from. A declining trend compresses what a buyer would pay.

   I used a website speed test to look at the differences before and after installing this plugin. Of course I waited a while for the merging and minifying to take effect i.e. I visited my website and moved from page to page. The plugin got the number of requests down by 20. What about speed? Well the load time does vary. Even without the plugin, sometimes the website responded a bit faster. It looks like this plugin has reduced the load time for my website by 0.8 seconds. To get this reduction in load time, I had to turn on “enable output buffering” and both “enable preload” options. Without these options turned on the speed increase was about 0.4 or 0.5 seconds. This an excellent result. Thanks very much. Now http2 is supposed to make merging have less effect. Is this really true? Is this still the case? Are all the effects from minifying or are they from merging as well? This topic was modified 3 years, 3 months ago by Marisa.

   It seems to me that: * if the CSS files has @includes it will not work. The option to skip CSS seems to be ignored * If the site is password protected (htpasswd protected site) the minifying part will be skipped.

   I discovered that autoptimize generated unwanted 302 redirections. There was a reason for it. autoptimize generates new CSS and JS filenames from time to time. So, then googlebot is lost and autoptimize creates a 302 redirect from old to newly generated CSS and JS files. If you disable their Merge, minify is much better. it uses variables in the URL to show new versions of files. For your information this is the WordPress approach. It is the best because, Googlebot understands it and it does not create a 404 or a 302 when a CSS file or a JS file is refreshed. To my knowledge this plugin is the only one with this approach. It is super simple. The developer of this plugin didn’t add useless features. i like it. You just install and it is ready out of the box. We don’t need other features. We need this plugin to remain efficient with new versions and to remain the best as it is now. I can see that in the background, this plugin does a great job. It reduces the number of files to the minimum and it is really lightweight. By far, this plugin is the best Merge, minify wordpress plugin

   Combines, but doesn’t properly minify .js and fails on dynamic parts of Woocommerce checkout page – vanilla theme – both .js and css.

   <!– wp:paragraph –> <p class=””>I tried autoptimize and it didn’t merge all JS scripts.. I remember I had 6 JS files MMR is much better and significantly decrease the number of javascript files (3 JS files for the same theme). Also, I haven’t seen any error in Google search console after using this plugin. Conversely, after using autoptimize, i got errors saying that some pages weren’t usable on mobile. PLus the plugin is easy to use. This is what we expect from a JS/CSS optimizer. </p> <!– /wp:paragraph –> This topic was modified 4 years, 1 month ago by bloup.

   My GTMetrix score went from F to A, but then it was so slow executing that Divi Builder would not load. I have max_execution_time settings of 120. As soon as I deactivated the plugin, Divi loaded fast again. It does a good job minifying and concatenating JS, CSS and HTML, but please look into this with Divi, as I cannot fault Divi on this. Please get back to me, as I prefer your plugin over the rest, if you can solve this Divi issue. This topic was modified 6 years, 2 months ago by DivSmart.
