Great Addon. Best results with this addon: 97/100 in Google Page Insights :) with C5 8.5.5 and php 7.4 :)
All-in-one solution to minify your page content, Defer your JS and CSS assets loading, Lazy-Load your images, videos, iframes and other media and Auto-Magically Take Your PageSpeed and LightHouse Scores Through the Roof and make Google Happy.
Instant Page Speed Magic automatically applies to your page you selected optimizations:
And absolutely everything is optional. You enable and disable what you want globally.
You also have a page attribute that lets you configure settings on specific pages if needed.
Yes, but how much depends on the kind of site you have.
At the very least your pages will be lighter because minified and compressed.
If you have 2 images and 1 script you might not see much of a difference with those options.
Other possibilities are available and they will all have some impact, again depending on your scenario.
Let's just say that if you already know you want to minify your pages because you care about your site being fast-loading, you'll be better served to get a tool that does more than just that. Every little bit counts.
The system is always disabled when a page is in edit mode and you can decide if logged in users with or without editing permissions also get the optimization or not.
Again, it couldn't be much simpler
Please, note that you can disable the whole system for specific pages using this attribute but you cannot enable it that way. Meaning that if the system is disabled globally you can't use this attribute to enable it for specific pages.
No, it can't.
This plugin doesn't modify your pages in any way. It only takes the content generated by Concrete5 and optimizes it before displaying it to the viewer.
If for any reason your site's front-end stops working, all you need to do is navigate to dashboard/system/optimization/page_speed_magic in your dashboard and disable the system. Everything will go back to normal right away with zero consequences for your site.
Also note that this plugin never ever affects your dashboard in any way, shape, or form.
It might but nothing that can't be fixed.
You can fix that by either
Yes, 99.99% of the time.
So if you have enabled the NO-JS option and you don't have CSS background images or don't care if users with no JS don't see them, then you're fine.
Of course, I can only vouch for what this plugin does. Anything you have on your page that requires JS, like galleries, sliders, custom players... won't work. But that has nothing to do with Page Speed Magic, that's just the way things are.
