Website acts as a business’ online presence; it is essential to leave a good first impression to website visitors to keep them coming back to you. Website speed influences users experience, thus it is important to ensure website is optimized.
There are several reasons why your website takes some time to load. It could be anything, but the most common factors are:
- Large image sizes
- Not using browser cache
- Too many widgets and plugins
- Hotlinking images and other resources from slow servers
- Traffic volume
- Older browsers
- Slow network connection (mobile devices)
One of the ways to overcome this issue is by enabling website cache.
What is website cache?
Cache is the process of storing copies of website files in a temporary storage location so that the website can be accessed faster. This is important to improve overall website speed and performance which is essential to user experience.
For WordPress websites, web administrators may install cache plugins on their site to enhance their website speed. There are many WordPress cache plugins available (both free and premium), choosing the correct one will significantly boost website performance.
For WordPress sites hosted on LiteSpeed Web Server, LiteSpeed Cache (LSCache) plugin is highly recommended to accelerate and improve website performance.
