First, please backup your files before you start modifying anything I write in this post.
First, why you should follow my advice? Well, almost anyone can tell you that a fast website is a good website and a good website is a mobile and desktop 100% compatible website but, as a developer, you need to test your site with Google’s Page Speed tool(https://developers.goo…).
Obtaining a good grade there can help your search engine traffic… So, what Google Page Speed score your project gets?
I’ve done a few projects with 98-99 out of 100, and a few with perfect 100.
I will list here a few “secrets” I used to boost my grade from 68/100 to 99/100.
1. Use only inline CSS
You need to use only inline css, period. Don’t link to any external frameworks(Bootstrap, etc.), don’t link to any Google Fonts file, to any particular style…
If you want to be productive, you ca use PHP to include_once(“”); your css files into the interpreted file.
If you want to use fontawesome or Google Fonts, you can put fontawesome file before you close your </body> tag.
You can also modify the Google Fonts .css file and include it inline into your source via PHP. Also, you can remove all the Vietnamese or Greek fonts from the Google Fonts file and use only the Latin style, works with english projects and most of the languages.
2. Insert the .js files at the end of the file
This is no secret that, inserting the .js files before you close </body> tag can get you a good Page Speed grade.
3. Use Server Side compression(gzip)
This is a pretty easy step, I provided instructions here on another post on how to do that.
4. Optimize images
Don’t exaggerate with images, use a low resolution image thumbnail, I use only < 10kb images. Specify the width and height of the image. You can use a free online tool to reduce the size of the images.
5. Minify css, js and html
This step gives anyone a lot of work if you are updating your site constantly… You can use free online tools to minify your css, html and js code.
6. Reduce the Server Response Time
Don’t load your server with requests, use, as much as you can only static content or make Ajax requests to content.
Transform your favicon in BASE64 text and include the code via PHP and get rid of a few connections that can slow down your website… I use this tool to convert my favicons: https://xaviesteve.co…
Hope this experience helps, try and play with this list and tell me your result.
