I’ve been looking at reasons why my blog has dropped from a PR5 to a PR4 and one of the reasons I’m suspecting is the number of broken/spammy links that my old blog had. I was running dasBlog back then and had a serious amount of trackback spam. I’ve been ignoring it since I switched to WordPress, and the pages just got spammier and spammier. For example, this page on BizTalk 2006 had around 300 links to poker and pharmaceutical websites. So I’ve gone in and modified the template not to show the trackbacks. Hopefully this will make Google think more highly of my blog.
