Pingback and trackback are concepts that often appear in the context of blogging (not just using WordPress), and which many people don’t quite understand. These techniques were created to enable automatic notification of the author of the entry about the fact that someone posted a link to their text somewhere. Although both are practically dying out (mainly because spammers often use them), it’s worth learning how they work.
Simply put, pingback is a notification that someone has placed a link to your blog on another page. It appears in the administrative panel between comments and is a small piece of text – exactly the text that surrounds the link to your post on someone’s page. If we included a link to your page in this text, then without even thinking about it, we would at the same time send you an automatic notification that you would find at your Website Between comments.
In other words, it’s a ‘ripped-out’ quote from someone else’s page, and it’s usually not suitable for comment. The information that pingback brings is “I have placed a link to your text in my post”, which (unlike trackback) doesn’t necessarily mean that the post refers to the linked text in any way. As you can easily see, the entry sending a pingback must contain a link to the pinged entry – in the case of trackbacks there is no such requirement. What are the differences between pingbacks and trackbacks in WordPress?
Trackback was invented as a way to inform the author of the text that our entry refers to it – comments on it or otherwise refers to it. Thanks to this, Entries on the same topic can be connected in some way. If our template supports the display of trackbacks, then information about them will appear between the comments, above them or below them – it depends on the choice of the author of the theme.
Unfortunately, sending a trackback is not easy or convenient. First of all, the addresses of entries that we refer to in our text have to be entered manually in the Send trackbacks field (by default it is hidden – they should be enabled in Screen options). This is intentional, because the trackback’s assumption is “I refer to your entry in my text” and not “there is a link to your post in my text”. The second difficulty is that the link to send the trackback may be different from the entry link.
If you want to send a trackback in the article content, you don’t need to refer to it. This feature was and is still used by spam bots. Good advice: if you get from another blogging a trackback, before you accept it, ask the author to provide a link to your blog directly, in the form of a link.
