Only a few users will have the patience to wait for more than 2 seconds for page to load. So, it’s very important to optimize page load speed. Let’s see how to improve website loading speed?

1. Optimize and Resize Images

Full-resolution images can take a long time to load. Images that have not been compressed causes slow loading, especially on mobile devices. No image should be over 100kb and you should never upload images directly without optimization and resizing.

Luckily, there is no need for high level of development skills for this, and you can easily reduce the size of your images, without any quality degradation through a number of free tools and plugins, if you have WordPress website. Images can be edited and loosely compressed using Photoshop/Illustrator and with many other free online tools.

Also, there are many tools and plugins for WordPress users that will automatically compress your images as you are uploading it to the website, like WP Smush.

2. Remove Render-blocking CSS and JavaScript files

CSS & JavaScript files are very important for your website,  because they control how your site will look and function. Render-blocking CSS and JavaScript files prevent your page from fully loading until they are processed.

You should avoid and minimize the use of blocking JavaScript and CSS files. If you have a lot of small CSS files, try to put them into one CSS file if possible. To remove Render-blocking Js you can make JS Asynchronous or preform Defer Loading of JS.

For WordPres users, there are plenty of plugins, of course. Some of them:

3. Use a Content Delivery Network (CDN)

A CDN can speed up your site by serving static files such as images, CSS, Javascript and other static files. A CDN will store your website’s static files (CSS, JavaScript, images, fonts, etc.) into a non-centralized file system around the world, and when user from another country visits your website, CDN will serve the files from the closest server to user’s location.

4. Enable the Website Compression

Website Compression can reduce the size of text-based files that the browser has to download and you’ll be surprised with results after enabling the compression.

The most popular compression tool for HTML, CSS and JavaScript text-based elements is GZIP. The configuration depends on your server. For Apache web server you’ll need to put some configuration rules into .htaccess file. For WordPress users there are always suitable plugin, check WP Super Cache.

5. Cache Your Website

Server Rendering time can really slow your website, but when your site is cached properly it can reduce your website’s loading time. Caching makes websites extremely fast, which leads to better SEO scores. Browser caching allows pages to load quicker as users navigate through the website by telling the browser how long to keep files stored. There are two very popular plugins for WordPress users: W3 Total Cache & WP Super Cache.

6. Minify HTML, CSS and JavaScript

Minifying HTML, CSS and JavaScript involves removing redundant text from a file, such as unnecessary text, data, white spaces, comments, characters, etc. t is recommended to perform minification just before releasing into production, as developers wont be able to read/edit them easily.

Removing redundant formatting, code comments and unused code will enable very fast loading time. There are plenty of free tools you can use to minify your files manually or automatically: Minify for CSS & JavaScript minification, JSCompress for JavaScript minificaton, etc.  As always there is W3 Total Cache for WordPress users, but this part  can be a little advanced for beginners.
