You don't have good results on Google PageSpeed Insights, because you are not enough care about the performance of your site! Each detail is important! It's all about the details!

You need to understand one simple thing - is not enough just to enable a few checkboxes of Gridbox Performance Tools and think that your site will get high results on Google PageSpeed Insights. Optimizing your site’s performance requires time and attention to each detail.

So, this article about details!

Cheap Hosting Vs. High Performance Score

What is the problem with a cheap (slow) hosting? You will not pass the “Server response time”.

Server response time is the amount of time it takes for a web server to respond to a request from a browser. The server response time should be no more than 200ms. or Google PageSpeed Insights will show you notice “Reduce server response times”.

Don't save on hosting! The fast server response is the base step to High Performance Score.

Simplicity is Your Key to High Performance Site

Gridbox allows you to embed one plugin inside another. That's amazing feature, absolute freedom of creativity.

But unfortunately, you very often abuse by this feature! Stop creating heavy structures! Tons of overlay sections with unlimited embedding cannot achieve high performance.

Stop creating heavy structures! Simple site structure - is Your Key to High Performance. The loaded truck will never run faster than a sports car. Just think about it!

High Performance Score Vs. High Resolution Photos

Non-optimized pictures are one of the most common issues. Absolutely each picture on the site should be optimized. Rules are simple! If your block width is 400px, the original size of the picture should be not more than 400px.

What's about the size of full screen pictures on the background? Let’s visit Browser Display Statistics. As you can see the most popular screen size is 1366x768. So, we recommend to use no more than 1400px, it will be enough! Don’t forget, that the background picture is a background picture. No reason to use high resolution photos since the picture will be placed under the content with overlay.

How to optimize pictures? Directly inside Gridbox, using Gridbox Photo Editor App, you can optimize (reduce) picture size and quality. Quality should be no more than 60-80%.

Yes, Gridbox Performance App includes “Automatic Image Compression”, but to get the best results, we recommend optimize each picture manually finding a compromise between size and quality!

Regarding pictures on mobile devices. Thanks to Gridbox Performance App, you can optimize all pictures automatically and it works perfectly. The max-width of the picture will be resized to breakpoint values. This means that the width of the image will be equal to the width of the device screen. The quality should be the same as on the desktop, no more than 60-80%.

Absolutely each image on the site should be optimized. Find a compromise between picture size and quality.
