How do I Speed up website using Pagespeed recommendations

[Nathan Nicholls]

I believe I have done all I can within the backoffice of prestashop to speed up my site (caching and CCC), our website lockoutdirect.com still sits at around a 70 score on google pagespeed insights. Google pagespeed is recommending I preload key requests and eliminate render-blocking resources. I am still learning and I am unsure what this means exactly / how to do it.

If someone could help and shed some light on the situation that would be awesome!

HI,

preload and delivering critical Js/Css code doesn't speed up your web site in most of the cases.

It gaves you the illusion that things will be faster, but, in a few occasion it could became worst.

You can check this link: https://developer.mozilla.org/en-US/docs/Web/HTML/Link_types/preload

 

But IMO you can speed up your site doing these things:

- using appropriate image compression (avoid .png images and any large images) 

- using a mix of colours-B/N images (lighter)

- disabling unused modules (desktop AND/OR mobile)

- disabling the preview animation product at least inside home page

- avoid using too much (and heavy) sliders/animations

- avoid using too much categories and themes that trigger dozens of requests on the server

- avoid using duplicated content/modules (generally happens with facebook buttons, multiple chat systems etc...)

- using Apache Gzip compression AND http2 on server

- using cache appropriately

- checking php.ini file (and options) through cpanel

- optimizing MySql db through phpmyadmin (just the automatic process is ok)

- reducing web crawlers/bots visiting your site through robots.txt and .htaccess
