Kramer is a plugin that will add inbound links to a post on your weblog as a pingback or comment. What this means is that when a post in blog A links to a post in blog B, blog B will find the inbound link and add it as a pingback or a general comment, without the need for the author of the post on blog A to send a ping to blog B. The way it finds the new links is by searching Technorati (http://www.technorati.com) for all new inbound to a particular post.

What this means is that pingback/traceback/trackback and other post-pinging tools are no longer required, as all links to a post will be found and shown as either pingbacks or general comments. To show links to the main weblog, or to other pages in general, a function called kramer_inbound() is provided. It can be used in Wordpress templates to display a list of the latest inbound links to that page. It is usually included in the sidebar of a blog and can be fully configured via the Kramer administration interface.

The plugin will also inform Technorati of new referrers, ie. other sites or blogs linking to your blog. This means that Technorati will be kept up-to-date about sites linking to your site and thus Kramer will insert these referrers as new pingbacks.


The latest version of Kramer is 0.6.1. It is available to download as a zip archive from:


The source and latest development versions can be viewed and downloaded at:



  1. The zip archive contains two files, README.txt and kramer.php. Place upload or copy kramer.php to your your wp-content/plugins/ directory.
  2. Once there, log into your weblogs administration console, click on plugins and then activate the Kramer plugin.
  3. Click on Options then Kramer to view the Kramer options page
  4. Under the API Key section, follow the link to Technorati to get an API key and insert the key into the field provided.
  5. Your installation is now complete, if there are incoming links to a post they should appear immediately.



The above screen shot shows inbound links to a blog post as comments for that post. The comments that are added as inbound links from Technorati as signified with the Technorati balloon.

  1. How can this plugin help me?
  2. It will show every post linking to your posts, in the form of comments or pingbacks. The blog post linking to yours does not need to ping your post for the comment to be shown in your weblog. This means that by default you can carry out conversatios between blogs.
  1. Is there a limitation on using Technorati?
  2. Yes, the limit is 500 queries per day, per API key. It is recommended that the cache time is set to 4-6 hours.
  1. How does the cache work?
  2. The cache time is the time taken between reqests to Technorati for new inbound links for a post, for each post.
  1. How do can I include inbound links for a page in my sidebar?
  2. Simply edit your template, and at the position that you want the list of inbound links place <?php $kramer_inbound(); ?>
  1. How can I change the position of the Technorati balloon icon?
  2. The balloon icon is defined with the class technorati-balloon that you can set in your style sheet.
