Pingbacks in WordPress are a way for websites to notify each other that they have linked to each other’s content. When another website links to your content, WordPress automatically sends a pingback to that website, letting them know that you have linked to their content.
Similarly, if you link to content on another website that has pingbacks enabled, WordPress will receive a notification from that website, letting you know that they have linked to your content.
Pingbacks are a way to create a network of interconnected content on the web. They can be helpful in promoting your content and building relationships with other websites in your niche.
By default, pingbacks are enabled in WordPress. If you prefer not to use this feature, you can disable it in the WordPress settings. If you choose to leave pingbacks enabled, you may receive notifications when other websites link to your content, and you can review those links to see if they are relevant to your website or content.
