How do I minify, compress and cache the linked JavaScript and CSS files

[cassiebond]

As we are unable to personally minify, compress and cache the linked JavaScript and CSS files connected to our sites, can you do it please.

I have spend a lot of time updating the SEO on both pages, running them through several checkers to get some form of continuity and the results RED flagged from them are identical.

JS & CSS are effecting the server configuration in a negative way quite drastically for both sites, especially for mobile devices. As most people search using their mobiles, a slow page loading speed will make people leave and find another site that loads properly, I know this is as a fact, because I have done it myself on lots of occasions.

I can work on improving our sites search engine rankings and drive business to our sites over a period of time, however, it will all be in vain if their website visit is a negative one due to the slow loading of each page, they will simply leave and not return, that means we are losing money.

Thanks for posting, @cassiebond. There isn't really a way to do that with a site right now. That can improve page speed, although limiting the amount of content and third party resources (like apps or embedded widgets) can make a bigger and more immediate difference. Those are also just recommendations, and unless they're causing a serious performance hit shouldn't really make much of an impact.

Hi Adam,

page speed on mobile has been considered a problem for long also for my website. I've reduced the amount of photos and third party resources to the minimum, but I still get reports to reduce render-blocking URLs by inlining critical resources, deferring non-critical resources (JS/style), and removing anything unused.

My website is   www.essercimeditando.it
this is one of the pages getting a red page speed (42/100)

and these are the suggestions:

Does weebly have special new themes designed for mobile?

I'm considering moving to wordpress where it seems I'll have more control on JS/CSS contents. Maybe I'm wrong about wordpress: I'm open to suggestions if you have any, on how to improve this JS/CSS issue, maybe through a weebly tutorial designed for people who would adventure into modify the code of their website...

Thank you for your help,

Albina

All of our themes should work well on mobile, although there are a few that I would describe as being designed "mobile first". I say that because they use the collapsed navigation all the time as opposed to only on small screens.

As for moving JS/CSS scripts, there isn't really a way to do that with a site unfortunately. This is my opinion so take it with a grain of salt, but the score that Google gives can be a bit misleading. It's scoring it based on what it gauges is a perfect speed. The actual real-world difference that you or a site visitor would see between a 100 score and a 40/100 score is not likely to be perceptible, though.
