SG Optimizer is a WordPress optimization tool developed by SiteGround. It can easily enable website caching and database Memcached caching to improve website response speed. Below, Naiba will teach you the specific setup method for SG Optimizer. First is installing SG Optimizer. We can directly search for SG Optimizer in the Plugins section of the WordPress Admin Dashboard to install it. Note: SG Optimizer requires SiteGround servers. If you are not using SiteGround, it is recommended to use
WP RocketIf you don't know how to install, you can refer to
WordPress Plugin Installation Tutorial. After installation is complete, you can see the SG Optimizer settings menu in the Admin Dashboard settings menu, as shown in the figure below:
Before proceeding with specific settings, let's go to the SiteGround Admin Dashboard to enable the Memcached caching feature (not supported by the StartUp plan). This caches database queries and can significantly improve website response speed.
The specific method to enable Memcached on SiteGround is: New Admin Dashboard: SITE TOOLS, then enter the Caching menu, find the MEMCACHED interface as shown above, and enable it. Old Admin Dashboard: Log in to the CPANEL panel, then find SuperCacher, enter, and enable the Level 1, 2, and 3 cache settings.
Below is a detailed introduction to the specific settings of SG Optimizer: 
In the SuperCacher Settings interface, enable Dynamic Caching and Automatic Cache Purge. If the website content is modified and the cache is not updated, you can manually click the PURGE CACHE button above to clear it.
The HTTPS button in the Environment Optimization interface: if you have already configured it, you don't need to enable it. Below is the PHP version selection; usually, the default is fine. Choose if needed.
The Frontend Optimization interface is for optimizing frontend code, such as compressing HTML code and merging CSS. You can enable all options. If a bug appears on the website interface after enabling a certain function, then disable it.
Image Optimization is for image optimization; it is recommended to enable it. Lazy Load images is for lazy loading images, meaning only images within the browser window are loaded; images not seen are not loaded by default, which can speed up web pages. However, if you enable it and the display is abnormal, disable it. The final Performance Test is a webpage scoring test, calling Google PageSpeed. A score around 80 is generally considered good. Of course, if after optimization you find the website score is still not high, or the speed hasn't changed significantly (actually, domestic access is mainly affected by the network), you can pay Naiba to help you optimize.
