We often get enquiries from website owners asking how they can improve the speed of their WordPress website. Before we can speed up the site, we audit the performance of the site to determine what exactly is slowing it down. There are three main bottlenecks we focus on:
- Files in the site are not optimised.
- The site is built from a theme containing redundant code.
- The server hosting the site is slow.
Let's explore some of these in a little more detail.
Files in the site are not optimised
- Files using the png image format can be substituted with smaller jpeg files.
- Image files are not sufficiently compressed.
- Css files may contain large amounts of redundant css.
- Css files are not combined.
The site is built from a theme containing redundant code
Excess use of WordPress plugins will eventually slow down your website. Unfortunately, it may not be possible to remove these plugins if they are required for your functionality. There is always the alternative of re-coding the plugins from scratch more efficiently, but this may come at a high cost of rebuilding website components.
The server hosting the site is slow
Shared hosting often results in slow sites. This can be established:
- In the Network tab of web developer tools in Chrome by looking at the time taken before data is received from a server.
- More reliably, move the site to a server of known performance and see if there is a speed improvement.
- Additionally, run the site through a content delivery network to provide global caching.
