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 up not being requested after all.
More info on https://instant.page.
Autopti
mize 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 to e.g. 20s or 3s or -and that’s where things get a teeny bit shady- 0s to disable the time-out, waiting for user-interaction to load the delayed resources.
Setting the delay to 0 is a bit shady because at that point you are hiding those assets for performance tests which -although artificial- is likely to improve (lab test) performance scores. If you do use the 0s delay then do take into account that *real* users will still need to load/ render those assets and that that still may be a sub-optimal experience.
So Autoptimize Pro has finally been released, somewhat secretively (I like flying under the radar).
All info about features can be found on https://autoptimize.com/pro/ including a 20% early birds discount code, but if you use my internet nickname/ handle of whatever you want to call it (it’s part of the domain of this blog and has 3 t’s in it 😉) as coupon code between now and November 16th, you’ll get an even bigger discount!
Be quick, your website will be too 😉
