Trackback and Pingback – Howto

What they do – an example.

[Note: throughout this document Blog-A is the remote blog, and Blog-B is your current blog.]

Suppose you read a post on someone else's blog, Blog-A say, and you think there is relevant content (posts and comments) on your site, Blog-B.

It would be helpful if readers of Blog-A could see the post and comments on your site Blog-B. That may be possible by using pingbacks or trackbacks.

Both, if moderated, add a comment to the remote blog.

This is explained in detail at

Is it possible?

It will be possible if

Here is how it is done:

There will be a delay before the link to the post on your blog (Blog-B) appears on the other blog (Blog-A). When a cron job
/usr/bin/php5 /home/sites/ is run on your website, the administrator of Blog-A will be sent a request to moderate your track-pingback.

If he chooses to approve it the title, excerpt (if any), and a link to your post will appear as a comment to the relevant post on Blog-A. It will not appear until the administrator of Blog-A has approved it.

What can go wrong

You are flooded with requests for moderating track-pingbacks

Track-pingbacks require manual moderation and thus increase the administrator's work load. Unfortunately most (possibly 90% or more) track-pingback links are spam from sites wishing for hits and are unrelated to the subject matter of your post, but you have to check each one before approving or trashing it. Not everyone thinks track-pingbacks are a good idea.


If you do not want track-pingbacks

  1. Uncheck the three items above in Dashboard -> Settings -> Discussion
  2. Stop the cron job(s) /usr/bin/php5 /home/sites/

No output on remote site


If you get a spam problem (with or without track-pingback) try using akismet . The akismet module is already installed. You just need to enable and configure it.
