The Relationship Between Website Performance and SEO

Website performance is an important component to good SEO. This is because Google will make faster pages rank higher, all things being equal. Moreover, a good user experience with less exits before the page is loaded will improve SEO naturally. This article will address common causes of slow Joomla website performance and how to improve it for Joomla SEO purposes.


Large and numerous images

Large and numerous images are the most common - and easiest to fix, of all website performance, Joomla or not. The solution is to resize as small as possible, compress and make progressive (if JPEG) or interlaced (if PNG). Formatting your images in this way will balance your performance and aesthetics optimally.


Complex or dense CSS and .js Files

If your Joomla website is running voluminous and complex CSS or JavaScript files, I have got news for you. This is a major stumbling block of good Joomla website performance. Loading all those CSS and Javascript files will slow down your page render significantly. You may have a very beautiful and function-abound website, but your performance will not be good and you will have a pretty looking dud. Simplify your CSS and JavaScript files as much as possible to ensure quick loading and efficiency.

SSL Certificates

If you have an SSL certificate on your website, it will improve its security. However, SSL certificates generally slow down communication between your website and server, leading to longer page load times.



If you have enabled the cache in Joomla, congratulations! You are on the road to optimising your website. However, caching is a double edged sword. You may find that you have problems of outdated caches, and that will slow down your website. The best thing to do is regularly clear the cache at an interval that is not too short that the cache cannot do its work, and not too long as to make it outdated.
