SiteGround Optimizer Plugin Settings

Are you looking for the “Siteground Optimizer Plugin Settings”?

Great, because Siteground optimizer (previously SG Optimizer) is the best cache plugin if you are using Siteground hosting.

Even you don’t need premium plugins like WpRocket.

I don’t say the plugins like WpRocket, W3Total cache, wp super cache, etc. are not good but with Siteground hosting, Siteground optimizer works best rather than these caching plugins.

And yes it works only if you have Siteground hosting because you need to enable some cache settings from the plugin as well as from your SiteGround Cpanel.

Update: Siteground Optimizer is now available to every WordPress user and not limited to siteground hosting clients only.

So, in this article, I am going to help you set up Siteground Optimizer plugin settings for caching.

Siteground Optimizer Plugin Settings & Configuration

Maximize the potential of your website with Siteground Optimizer Best Settings.

Discover the optimal configurations and advanced tweaks to enhance performance, improve loading speeds, and elevate user experience.

1. Install & Activate

First of all, you need to install and activate the SG Siteground Optimizer plugin.

Go to plugins- Add new- Search Siteground Optimizer- Install-Activate- Done.

2. Dashboard

In the dashboard section, you can check your caching status. 

You can check which settings are enabled and visit directly to other settings with a single click.

3. Caching Settings

Dynamic caching – Enable

Store your content in the server’s memory for faster access with a full-page caching solution powered by NGINX.

Having a Dynamic Cache is essential for speeding up your website.

File-based Caching – Enable

With file-based caching enabled siteground will create static HTML versions of your website which will be served to future visitors.

The files are stored in the browser’s memory.

Memcached – Enable

Powerful object caching for your site.

Memcached stores frequently executed queries to your databases and then reuses them for better performance.

Automatic Purge – Enable

When clearing the cache – purge the WordPress API cache too – Enable

When enabled, the cache will be purged automatically without performing manually.

Manual cache purge – Purge cache

Use this to cache purge manually when the automatic purge is disabled.

You can use this option when you’re modifying new content and don’t have automatic purge enabled to make sure that old cached is purged right away.

Exclude URLs from caching – “add URLs here by clicking on the edit button”

You can add URLs here that you don’t want to cache like sitemap URLs.

Browser specific caching – Enable

Generate caching separately for different browsers.

Enable this feature only if you’re experiencing issues with plugins generating mobile versions of your website or other similar functionality.

This feature significantly lowers caching efficiency.

Recommended but Cloudflare is best for this.

4. Environment Settings

HTTPS enforce – Enable

It is recommended but useful only for siteground hosting users.

It configures your site to work correctly via HTTPS and forces a secure connection to your site.

In order to force HTTPS, siteground will automatically update your database replacing all insecure links.

In addition to that, Siteground will add a rule in your .htaccess file, forcing all requests to go through an encrypted connection.

You can enforce https from your hosting CPanel or using Cloudflare.

Fix insecure content – Enable

Enable this option in case you’re getting insecure content errors on your website.

Siteground will dynamically rewrite insecure requests for resources coming from your site.

Insecure contents are also called mixed contents.

GZIP compression – Enable

This enables compression of the content that’s delivered to your visitors’ browsers improving the network loading times of your site.

It is recommended as this can reduce the size of your files.

Browser caching – Enable

Cloudflare is better but you can enable this if you are not a Cloudflare user.

Enabling this will add rules to store the static content of your site longer in the visitors’ browser cache which improves the site performance.

WordPress heartbeat Optimization – Disable

Recommended by Siteground but I personally don’t recommend enabling this option.

Heartbeats will increase your server load resulting in increased CPU usage.

The WordPress Heartbeat API checks your post edit pages every 15 seconds and your dashboard and front end every 60 seconds, even in the absence of scheduled tasks. 

However, You can modify these settings to reduce load.

Schedule database maintenance – Enable

I always recommend optimizing your database and this option will clean up your database once a week to keep it small and optimized.

Tasks performed by this option,

-Perform Database Optimization for MyISAM tables
-Delete all automatically created post and page drafts
-Delete all page and post revisions
-Delete all posts and pages in your Trash
-Delete all comments marked as Spam
-Delete all expired Transients

However, I recommend using WP optimize plugin for advanced database optimizations.
