Website Optimization and Google Page inside score and some warning

Published on : April 27, 2026

To determine a website strength or speed we used mostly google page inside tools. Everyone will look for Green signal on google page speed (the green color comes if speed score is more than 85).

Before Optimize the site speed is:

Consider Magento site what can we do to speed up a Magento site.

Optimize all image and media files
Combine CSS file
Combine JS files
Moving all JavaScript files to bottom and CSS file to Top
Minimize Server Response by Optimize Query and Caching extension or server caching
If your site have much product then enabling the flat category product
Enable Magento Cache and the Zend Cache

After implementing all of this my speed now come to

It’s improved lot but not the best,

If you look carefully all the rule is passed here, for Magento site or big site the following error shows that reduce the score. Sometimes it hard to make understand to a non-technical person to this issue, because they will look for score not what is good practice or bad practice.

Now let’s explain one by one

Should Fixed

Eliminate render-blocking JavaScript and CSS in above-the-fold content. Here it shows that one CSS file blocks the render above the fold content, this means mobile device first screen’s worth –anything you don’t need to scroll to see.

So to remove this error google recommend “OptimizeCSSDelivery” message. There they told inline the “above the fold” CSS. Here in the sample site the above the folds contain header part and the slider part. So I have to inline all the CSS with media query to inline to remove the error. In Magento, this part is Huge that contain lots of CSS. So if we implement this process the following advantage and disadvantage happen

Advantage:

Your score will increase
As CSS comes directly with HTML so CSS request will decrease
Page will load faster

Disadvantage:

Portability of code will be decrease
If we don’t inline that CSS browser will take time to load first time the CSS and for other pages, it will load from cache, so if we inline this we cannot able to get this advantage
Static content caching will not work.

# Of course, google have server solution for this they provide “Page speed module” for this, you need to contact your server administrator to install this. You can use on Apache and Nginx based server on all server Linux distribution.

This has many features, like combining CSS, JS, and Compress static files, Lazy load image and etc. But the issue remains same for above the fold content rendering issue.

But this is recommended for another optimization process.

Server Reduce Time:

For a large site, there may lot of database query, images, js and others things need to load the site. That’s why the server response shows error. To fix this the following this you can do
Optimize database query.
Server caching like Memcached, Varnish, Stash, Doctrine, etc.
Based on your website you can use caching extension for full page cache. If your site is small or big doesn’t matter but if your content frequently changed then of course clear cache every time you did some changes
You can use CDN services.

Leverage browser caching

You can enable browser caching for your authorized domain, but for the external website its no on your hand, so cannot control caching of them. Example if you browse a website that loads some CSS and image file for the first time, and the second time if you browse same page or another page and if the static files is a match then it will not load another time browser will show the cached version of the files.

Basically, this error shows for Google analytics tracking Code, Facebook Pixel, Bing Pixel code, etc. You cannot control them, so try to use small amount pixel code.

As many people found this error only for google analytics code. As google page speed tools are owned by google so why google showing their product google analytics code as an error, actually this is not fair. There may have some solution to minimize the warning like bellow

Host the analytics JS (//www.google-analytics.com/analytics.js) file on your hosting and link google analytics code. But Risk is yours. If you forced to make page speed high then you can use this method.
You can use Page Speed Tools and on Google Analytics Asynchronous to minimize the warning. But be careful Page Speed Tools is totally server based part.
