I’ll split this article into two parts. Initially, I’ll talk about a basic and fundamental step which require no coding and second part (in next article) which is more technically and advance.

By the end, I hope everyone will be able to take at least a couple of the ideas and apply them immediately to make the web a faster place for us all!

Install a WordPress caching plugins

Caching can make your WordPress site anywhere from 2x to 5x faster.

Here’s how it works: Instead of going through the whole page generation process every time, your caching plugin makes a copy of the page after the first load, and then serves that cached version to every subsequent user.

There are a lot of caching plugins available for WordPress, but we recommend using the WP Super Cache plugin. Check out our step by step guide on how to install and setup WP Super Cache on your WordPress site. It’s not difficult to set up, and your visitors will notice the difference.

Optimize Images for Speed

Compressing images could make them smaller by 30% – 80% without any noticeable difference.

Before you upload a photo directly from your phone or camera, we recommend that you use photo editing software to optimize your images for the web.

In their original formats, these photos can have huge file sizes. But based on the image file format and the compression you choose in your editing software, you can decrease your image size by up to 5x.

most well-known formats are JPG and PNG,

Well, PNG image format is uncompressed. When you compress an image it loses some information, so an uncompressed image will be higher quality with more detail. The downside is that it’s a larger file size, so it takes longer to load.

JPEG, on the other hand, is a compressed file format which slightly reduces image quality, but it’s significantly smaller in size.

One of the best tools to use is, of course, our very own WP Smush Pro, which is used by over 200,000 WordPress installations. You can even resize images automatically.

I personally use Imageoptim for OS X to mass-optimize images or you can use the popular RIOT on Windows.
