Trackback – Howto

What trackback does – an example.

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 or may not be possible. There are two ways of doing this – pingback and trackback. This article deals with trackback – see pingback.html in the same directory for 'Howto Pingback'.

The difference between pingback and trackback is that what is shown on the remote site. With pingback readers of Blog-A, see a link to your site, Blog-B. With trackback your post on Blog-B is reproduced as a comment on Blog-A, and since it is possible to spoof the source address, readers of Blog-A may be misled as to who really posted the comment. With pingback spoofing the source just links to a different site (possibly non-existent).

Is it possible?

It will be possible if

Here is how it is done:

It may happen almost immediately or there may be a delay before the taster and a link to the post on your blog (Blog-B) appears on the other blog (Blog-A). Most site administrators require contributions to their blog to be moderated before publishing, particularly in the case of trackbacks which could contain offensive material or links to undesirable sites.

What can go wrong

No output on remote site


Many Blog sites do not enable trackback because of the problem with 'Comment Spam'. If you get a spam problem (with or without trackback) try using akismet. The askimet module is already installed. You just need to enable and configure it.
