What is a Pingback?
A Pingback is basically the same as a Trackback. From a technical point of view, they both are very different, but these differences are not relevant to us.
So, what distinguishes a Pingback from a Trackback in our everyday use? Easy... Pingbacks require that the originating site posts a link to the receptor site within the text that references the receptor site. Actually, pingback equipped platforms physically check if such link exists in the originating site in order to complete the acknowledgment process.
These differences give Pingbacks two advantages over Trackbacks:
1. Pingbacks do not require the you to enter a 'Trackback' URL when composing the message (Posting a link within your message is good enough). This is by far the easiest method, since you don't have to think about it or do anything.
2. Pingbacks allow you to reference anchors (posts) within threads while Trackbacks can only reference threads as a whole.
Originating site (apple) may Trackback a receptor site (orange) using a 'Trackback' URL specified by orange. Now, apple may Pingback (link to) orange by referencing the following URL(s) in a common paragraph:
On a Pingback equipped forum, incoming Pingbacks that reference individual posts will be identified accordingly in the Ping/Trackback table:
You can Pingback other sites from APC
Pingback another site from our forums by simply including an outgoing link within your post.
