Visualize recent visits from media companies with MediaCreeper
First, make sure your site has a MediaCreeper tracking tag somewhere in the pages. Version 1.1 of the MediaCreeper plugin for WordPress includes an option in the settings panel to automatically add the tracking tag to the footer of your pages. Alternatively you can add the necessary code yourself to your pages.
MediaCreeper only tracks visits from IP blocks known to belong to media companies. If you're not getting any data then that is perhaps because your blog isn't attracting any traffic from any of the tracked media companies.
