1. Make sure you’re using a lightweight, well developed theme
If you’re using a poorly developed theme, you’ll most likely have a longer server response time than a well developed one. If your theme is developed just for your site you should expect to have a relatively low server response time but if you’re using one of the many pre built themes on the market it’s best to go with something a little bit minimalist as that will have less assets to load.
Another thing you can do is take note of page speed when trying out a WordPress theme, most themes will let you view before you buy.
2. Avoid installing too many plugins
When you manage a WordPress site it’s very tempting to install plugins that you think will benefit the site but with most plugins they usually increases the server response time slightly and loads in more scripts for the plugin to se which will also adds to the page load time.
Before installing a plugin ask yourself “Is the feature I’m adding worth sacrificing a few milliseconds of my page load speed?”
3. Install a decent caching plugin
There are quite a few decent caching plugins out there, you may have to try a few different ones to see which ones positively affect your page speed the most. The effective caching plugins are usually paid plugins but offer a free version with limited functionality, if you’re looking for a great plugin that proves to be most effective (in my experience), you should check out WP Fastest Cache.
4. Optimise your images
The images on your site can sometimes be larger than they need to be, in many cases they’re over twice as big as they display on your page.
Luckily WordPress has a build in tool that allows you to crop and resize images, you can edit images as soon as you upload them or you can go to your media library, select and image and then press “edit image” and it’s as easy as that. A great feature of the WordPress image editor is that it will resize in proportion with the original size when you add either a new height or width, this way your images won’t be distorted in any way.
