Get Started With Pingbacks

All you really have to do is link to another post.  

Behind the scenes, a pingback notification will be sent to the other blog, prompting the other site owner to approve the pingback.  

It’s very much like a comment awaiting moderation - the only difference is that it was automatically created.

Check the main WordPress user interface and click on Comments, then filter by Pings.

Once there, you can approve pingbacks one by one, or en masse.

If you’d like to remove, or delete a pingback, or several pingbacks, login to the main WordPress user interface and click on Comments, then filter by Pings.

Once there, you can delete pingbacks one by one, or several at once.

In HTML, links are signified with the <a>, each having rel=”attribute” where attributes can be one or more of several different values.

Rel values indicate the relationship of the target resource to the resource on which they appear ¹⁾ thanks Microformats for that explanation.

Here’s a relatively full list of popular link rel= attributes:

• alternate: signifies this is the alternative version of the content such as a page destined for print, translation or mirroring

• noreferrer: signifies that a browser should omit the HTTP referer header when following the link
• pingback: signifies that the content can accept pingbacks and what is the URL of the pingback server (absolute URI of the pingback XML-RPC server)
• preconnect: signifies that a browser should attempt to connect before page load completes

Notes:

    <a> tags are typically used like:
    <a href=”https://www.someserver.com/” rel=”external, nofollow”>a bit of target information</a>

You can use one or more attributes in the rel=”attribute, attribute, attribute”, provided they are comma separated and quote encapsulated.

Pingbacks can be marked up via the HTML rel=”pingback” attribute, but that information can also be passed along via the HTTP header as:

X-Pingback: ³⁾http://charlie.example.com/pingback/xmlrpc

Thanks to the ⁴⁾archive at cweiske.de for a good example of the HTTP header which has passed the X-Pingback details.
