How to know which other sites or blogs contain the same publisher ID? I'm not into hacking or something I just want to know this to trace those sites that I don't know.. thank you
you can use this tool http://spyonweb.com/, enter the publisher id and it will display all the site the uses them..
It is also available in seo quake tool bar.... Cool one. But if the list is too much, you have to pay them.
