Often while browsing Facebook groups and public forums, I have seen webmasters struggle with speed and performance of their website or blog.

And one of the reasons for this problem could be the hosting service you are using and that is why it is always recommended to host a website on a reliable service provider like SiteGround.

SiteGround is one of the best web hosting companies in the market today and is known for its speed. On top of this, it hosts over 2 million domains and is on the recommended list of hosting providers by WordPress.org.

And in this tutorial, we will be covering everything you need to know about SiteGround SuperCacher and how to activate it. Below are all the topics that we have covered in this article.

  • What exactly is SiteGround SuperCacher
  • Different levels of SiteGround SuperCacher
  • How to activate Supercacher
  • SuperCacher settings

Having said that, lets start the tutorial and dive into the first topic

What is SiteGround SuperCacher

SiteGround SuperCacher

SiteGround SuperCacher is a web based server side cache solution developed by SiteGround exclusively for its users. According to SiteGround, using SuperCacher can significantly increase the number of hits a site can handle which in turn leads to improving the loading times by 4x.

Till now you may have noticed, we have used the word “cache” or “caching” more than a few times and in case you are not familiar with this then let me tell you briefly about it.

A cache is a space or a storage where temporary files related to your website are stored. Whenever a request is made, it is completed by retrieving the stored files from the cache without disturbing the server.

And this significantly improves the speed of a website or a blog.

Similarly, SiteGround Supercacher is the caching solution which when enabled is deployed between the user and the web server and being a cache solution stores a copy of your site on it.

Now, when a user visits your page, the SuperCacher completes the request by displaying the information stored and this drastically improves the speed of the website.

Before we move forward, it is important to know if you do not enable SuperCacher or have no other caching solution in place then the request completion process can take time as every request generated will be directly fulfilled by by the server causing your site to load slow.

Also, every website receives hundred’s of requests each day and if every request is completed directly by the server then this can easily consume your CPU limits. And you don’t want that.

Having said that,

SiteGround SuperCacher offers 3 layers of caching

NGINX Direct Delivery

NGINX Direct Delivery is the static cache and this is where a copy of the static content of your website such as HTML, CSS, JS or images is stored.

Now, whenever a request includes any of these files, it is completed by serving files from this storage. Enabling this will considerably boost the speed of your site.

This cache is suitable for any type of website hosted on SiteGround.


Memcached is a very popular database caching system used by may popular websites such as YouTube, Facebook, Wikipedia and more.

Enabling this cache will store an output of the database queries and this means if the result of the same query is required again then rather than generating it from database, it will be retrieved from the cache.

Dynamic Cache

Dynamic cache is very different from both NGINX Direct Delivery and Memcached because it does not cache part of your website, rather it caches the complete web page.

Considering you have a website built using WordPress which is written in PHP and the output users see on the browsers is HTML.

Now, when you enable Dynamic cache it stores an HTML output of the page you have created in WordPress and serves it directly from this space.

How to enable SuperCacher in SiteGround

Now that you understand what exactly is SiteGround SuperCacher and different levels of caching it offers. The next topic we are going to discuss is enabling SiteGround SuperCacher.

Activating SiteGround SuperCacher is a 2 step process that includes

  • Enabling it in SiteGround Site Tools
  • Activating it in SG Optimizer

Before we dive into the process, it is important to know SiteGround does not offer this speed optimization service on the StartUp Plan.

This means if you are currently using the StartUp Plan then you won’t have access to this feature and to use it you will have to upgrade to either GrowBig or GoGeek plan.

In case you have landed on this page and still haven’t invested in SiteGround yet then I will suggest doing it now. And using our exclusive SiteGround discount coupon you will get 60% off.

How to buy hosting from SiteGround (if you haven’t)

If you are looking to start a WordPress blog then select WordPress hosting and after selecting it will take you to the pricing page.

SiteGround Pricing and Plans
SiteGround Pricing and Plans

Here you will have to select a plan. As this tutorial is about SiteGround SuperCacher and this feature being available in GrowBig or GoGeek plan, I will suggest selecting between these plans only.

After selecting a plan, it will take you to a new page where you are either required to provide an existing domain name that you own or you can buy a new one from SiteGround.

In case you want to buy a domain name then I will recommend getting a .com domain in 99 cents. Using this deal you can save some money as SiteGround does not offer a free domain name with its plans and it will cost you $15.95/ year extra when you buy from them.

Having said that,

Once you have entered the domain name in the box, click Proceed and it will take you to a new page wherein you will be required to create an account and proceed with the payments.

After you are done buying hosting the next step is to install WordPress on SiteGround

Browser Specific Caching

In case your site is experiencing issues related to generating mobile version of your site then enabling this setting will help.

When you activate this, a separate cache will be generated for different browsers which lowers the efficiency.

Keeping this in mind, only enable this option if required.

Excluding URL’s

If you want to exclude certain pages or parts of your site from being cached then you can add its path in the space provided and those sections or pages won’t be included in the cached version.

Test URL’s for cache status

In case you want to check if dynamic cache is working on certain URLs then you can add the URL’s in the box and test. This feature is especially helpful to check excluded URL’s are actually excluded.

This concludes all the settings you have to configure when enabling SiteGround SuperCacher on your website.
