Firstly, you should turn off the default WP-Cron behavior to prevent it from running on page load. For this, access the wp-config.php file located in the root directory of your WordPress site. Just before the "/* That's all, stop editing! Happy publishing. */" comment, insert the line:
define('DISABLE_WP_CRON', true);
After deactivating the WP-Cron, you must establish a manual cron job to regularly invoke the wp-cron.php file. A thirty-minute interval is generally ample for most sites. Proceed by navigating to your hosting account's control panel and locating the Cron Jobs section under Site Tools > Development.
There, you can input the following command to execute it every half hour:
cd /home/customer/www/yourdomain.com/public_html; wp cron event run --due-now >/dev/null 2>&1
Do not forget to switch out "/home/customer/www/yourdomain.com/public_html" with the real directory path where your WordPress is installed. If you prefer to get email feedback after each cron run, simply remove ">/dev/null 2>&1" from the end of the command.
Often, the cron job interface will have preset common intervals. In this case, you can select the option for "Twice Per Hour" from the provided interval options instead of manually entering the schedule.
