A pingback is basically an automated comment that gets created when another blog links to you. A self-pingback is created when you link to an article within your own blog. Pingbacks are essentially nothing more than spam and simply waste resources.
Follow the steps below to disable self-pingbacks.
Click into the Perfmatters plugin settings.
Under the “Options” tab and “General” sub-navigation menu, toggle on “Disable Self-Pingbacks.”
Scroll down and click “Save Changes.”
