Speed Up Your SiteGround Website

Speeding up your website, so that it loads under 2 seconds might be the most important thing you can do for a website.

Nobody likes to wait more than a couple seconds for a website to load. We will leave for another website.

The best thing to do in order to speed up your website is to use a cache plugin.

In this post, I’m going to talk about speeding up your Siteground-hosted website. This does not pertain to custom made websites with own custom servers.

You will need to make a couple of changes in Siteground and in the Siteground created plugin, SG Optimizer.

What is a Cache Plugin?

WordPress is created by PHP code and has a backend database that manages and updates your website. This makes the web pages dynamic.

A static website is just HTML, CSS, and maybe some Javascript. The content doesn’t get managed or updated by a backend database. You edit the files directly and they load faster than dynamic webpages.

And what does this have to do with a cache plugin?

A cached plugin generates a static HTML page and saves it on your server.  Each time a user accesses your website, the cache plugin will serve up the lighter static HTML page, instead of loading the slower dynamic one with PHP scripts. This makes load times faster for your website.

How to Install The Plugin

There’s only one plugin you need to speed up your website and it’s called SG Optimizer.

Here’s how to install it. First go to your WordPress Dashboard > Plugins and Add New

Search for “SG Optimizer.” Install and Activate it. It looks like this:

Siteground Settings For SuperCacher

Now that you have the plugin installed and activated, we’ll need to make some changes to your SiteGround managed website.

Login to SiteGround and go to My Accounts.

Next Go to cPanel.

Then click on SuperCacher icon in cPanel.

Important: SuperCache is only available for the GrowBig and GoGeek hosting plans from SiteGround. It’s not available for the StartUp plan.

Here you’ll see tabs for Level 1: Static Cache, Level 2: Dynamic Cache, and Level 3: Memcached.

Level 1: Static Cache is enabled already by default, so don’t worry about that one.

Level 2: Dynamic Cache may or may not be enabled. Make sure to enable that.

Level 3: Memcached is not enabled by default. Go ahead and enable this as well.

Below are the recommended settings for this plugin.

There is a lot of technical jargon here. If you want to know exactly what each of these things does to help speed up your website, go to SuperCacher Controls in SG Optimizer.

Speed Test Results

Here are the speed test results for the blog you’re currently reading. This speed test is from a website called isitwp.com. Load time is 855 ms. Pretty good.

Here’s another speed test result from a website called pingdom.com. The speed test result here is a little slower at 1.48 seconds. But under 2 seconds is good.

Other Ways to Speed Up Your Website

Some other ways to decrease the load time of your website is to only install plugins you need for your website to work. Delete the rest. Some plugins use too many API (Application Programming Interface) calls that can slow down your website considerably.

Also, make sure to permanently delete images you don’t need and optimize the ones you do need. The smaller the size of the image, the better, just don’t sacrifice quality for speed. I like all my images between 10 to 500 kilobytes compressed .jpeg image format.


In this post, I talked about speeding up your SiteGround managed website. I went over what a cache plugin does, how to install the plugin, settings for SiteGround and SG Optimizer plugin.

I also showed you my speed test results from two speed check websites and some other ways to speed up your website.
