Why having a fast loading website is so important? Page load time affects two important factors that may have influence on the success of your site: seo rank and conversion rate. Lets take a look on what you can do to improve performance of your Joomla website.
1. Choose a good web hosting
Web hosting is the most important thing. All other performance tips may be useless, if you do not have a good and fast web hosting. I suggest you to read some reviews and forums to find the one that will be perfect for your site and needs.
2. Keep Joomla and extensions up-to-date
Beside security reasons, having the latest version of Joomla core, extensions and templates is very important for your website performance. Usually the new version achieves some code improvements and work better than the old version.
3. Remove unused extensions
Each extension installed on Joomla is taking some system and database resources. Usually there are also some additional CSS and JS files loaded into the head section of your template which may increase the overall size of the whole website. A good practice is to keep only those extensions which are currently used on your site. If you often test new extensions, remember to uninstall them if you do not use them.
4. Enable Joomla caching
If caching is disabled, when a user visits a page, all data needs to be loaded on each page request. As you can imagine, such process takes some time. By enabling Joomla caching, if someone will visit your site for the first time, all data will be cached and stored as lighter and faster content that will be loaded for all the next visitors.
5. Enable GZIP compression
Another way to speed up your site directly from Joomla settings is compression. When compression is enabled, your site pages are downloaded as zip file and unpacked by browser. This way it is possible to reduce the content size over 50-70%.
To enable this option, go to System → Global Configuration → Server and choose Yes for the Gzip Page Compression option.
6. Optimize images
Usually, images take the biggest part of the overall website size and this is the main reason why they should be optimized. Take a look on the most important tips regarding image optimization:
avoid using large images on your site
do not scale images using HTML or CSS
remember to add the width and height attributes for each image so browser will know their dimensions before downloading them
7.Mobile friendly optimization
It has been almost two months since Google launched a new mobile algorithm. It means that mobile friendly websites get a higher rank in the search results on mobile devices. That is not a surprise since over 50% of online traffic comes from mobile and tablet devices.Using Mobile Friendly Test you can check if your website is mobile friendly or not.
