A pingback is a special type of comment that’s created when you link to another blog post, as long as the other blog is set to accept pingbacks.To create a pingback, just link to another WordPress blog post. If that post has pingbacks enabled, the blog owner will see a pingback appear in their comments section.
Think of them as automated comments:
- Person A publishes a post.
- Person B publishes her own post, including a link to Person A’s post.
- WordPress.com automatically sends a pingback to Person A’s post.
- Person A’s post receives the pingback, then automatically goes to Person B’s post to confirm that the pingback did, in fact, originate there.
- Person A’s post then displays a special type of comment highlighting Person B’s post.
Pingbacks will appear mixed in with any other comments on the post:
The example above is from a blog using the Ryu theme. Comments are styled differently for each theme, so pingbacks on your blog won’t necessarily look like this example.
Can I stop self-pings?
Self-pings (pingbacks that happen when you link to your own blog posts) are useful to some, annoying to others. If you’d prefer, you can stop your blog from pinging itself by using a shortened version of your URL for the link.
Normally when you create a link, the entire URL including
http:// is used. That will cause a self-ping.
To prevent self-pings, remove the domain from the link, keeping only the slug — the part of the URL that comes after the “.com.” Instead of this:
use only this:
Note: The Visual Editor may add the domain information back into the link. To check, switch to the HTML editor and make sure the link is displayed correctly in the href attribute for the link before publishing. Also, the relative link structure suggested above only works within the blog itself. The links will be invalid when used outside of the blog, like in subscription emails.
How do I send out update pings?
Many services like Technorati, Feedster, Icerocket, Google Blog Search, and others want a “ping” from you to know you’ve updated so they can index your content. WordPress.com handles it all for you. When you post, we send a ping using Ping-o-Matic!, is a service that pings several different search providers all at once including Technorati, My Yahoo!, and Google Blog Search.
Pings are automatically sent if you have a public blog. If your blog is private or if you block search engines, pings will not be sent.
You can disable pingbacks on individual posts via the Discussion module on your Add New or Edit Post page:
Look for it in the modules to the left of the post editing box.
