Updating the WordPress cron is one of the easiest things you can do to speed up your website, esspecially for new visitors.
Think of the WordPress Cron Job like the Personal Assistant for your WordPress Website. The Personal Assistant (Cron Job) has jobs to do at regular intervals eg. Hourly, Daily, Monthly etc. But the only way that the Personal Assistant (Cron Job) is able to start her work, is by someone visiting your website and waking her up. This means that not only does your Wordpress website have to show the customer the page, it also has to complete any tasks it has missed. This equals slow load time for that customer.
To use the WordPress cron, follow this guide:
Step 1 - Log in to cPanel (click here for a guide) and click on File Manager
Look for the wp-config.php file (it's normally in the public_html folder)
Right click (or command+click in mac) and click Edit
Click Edit again if you see this popup
Step 2 - Under the line which starts with "define('WP_DEBUG', type this: define('DISABLE_WP_CRON', true);
Afterwards, click (1) Save Changes, then (2) Close
Then click the cP icon in the top right to go back to cPanel
Step 3 - Click on the Cron Jobs icon
Set the Hour to: Every Sixth Hour
Undeer Command type: wget -q -O - http://yourdomain.net.au/wp-cron.php?doing_wp_cron >/dev/null 2>&1 (make sure to replace yourdomain.net.au with your domain name)
Once that's done, click Add New Cron Job
