Performance hack seen on a customer site; fix the bad LCP (due to an animation in revslider) by loading an inline (base64’ed) png image which according to FF is broken and later in the rendering process hiding & removing it. Even though that image is not *really* used, tools such as Google Pagespeed Insights pick … Read more
I just reviewed the performance of a customer’s WordPress site. Things got a lot worse he wrote and he assumed Autoptimize (he was a AOPro user) wasn’t working any more and asked me to guide him to fix the issue. Instead it turns out he installed CookieYes, which adds tons of JS (part of which … Read more
As of Autoptimize Pro 2.3 there is an option to delay all JavaScript. Delaying can have a bigger positive performance impact then asyncing or deferring because AOPro will only load the delayed JS after a to be defined delay or (better even) only at the moment user interaction (such as swiping/ scrolling or mouse movement) … Read more
Ever since the advent of HTTP/2 people asked if they still needed JS/ CSS files to be combined and indeed by default aggregation is off in Autoptimize. But based on this interesting article by Harry Roberts, “bundling is here to stay for a while”. So when in doubt; test performance with and without aggregating CSS/ … Read more

Especially iframes can consume a lot of … Read more
I just released Autoptimize Pro 2.0 as beta and now AO(Pro) finally includes page caching. If you’re on Cloudflare (APO), if your host offers page caching at server level (nginx/ varnish or similar) or if you already have a page caching plugin then you don’t need page caching in AOPro, but based on discussions with … Read more
New booster in Autoptimize Pro 1.3: instant.page, a 3rd party JS component that can significantly improve performance for visitors going from one page to another on your site by preloading a page based on visitor behavior. Do take into account that it could increase the number of page requests as the preloaded page might end … Read more
Autoptimize Pro has “Boosters” to delay JavaScript (esp. interesting for external resources), CSS and HTML (which can be very impactful for long and/ or complex pages). Up until today’s release the delay was either until user interaction OR a set timeout of 5 seconds, but now you can choose the delay time yourself, setting it … Read more
My friend and #WordPress performance guru Bariş is from Turkey and is asking for help from the WordPress ecosystem. Share as widely as possible!
It has been long overdue, but I’m finally almost ready to release Autoptimize Pro. The first version of AO Pro (an add-on to be installed on top off Autoptimize) will have Image optimization, CDN, fully automated critical CSS and a number of “boosters” to improve performance even more, with more features are in the backlog. … Read more
