SiteGround Website Optimiser Plugin

SiteGround Website Optimiser will help improve the performance of your website, further drive traffic, increase conversions and grow revenue.

What is an Optimiser?

In this topic, we will cover how to set up and optimise the SiteGround Website Optimiser plugin (SG Optimizer). This is a powerful plugin tool that comes pre-installed on all of PODTech hosting plans. 

SG Optimizer has many features but is calibrated specifically for PODTech’s Google Cloud servers. Most good hosting providers will have their own calibrated Optimiser.

There are more advanced website optimisers out there, like W3 Total Cache. But if you’re after a quick, lightweight website optimiser plugin SG Optimizer is for you!

Installing a site optimiser will give it a noticeable speed boost. However, some of the settings may cause your site to “break”. If this happens to you, do not panic as your information will still be there and the issue is easily resolved. If your site “breaks” as a result of optimising your SG Optimizer read Common Website Troubleshooting TipsThis will guide you through the common issues with the plugin and how to resolve them in no time.
