Up until yesterday I was ranking very competitively for a lot of my keywords on the new beta MSN. Today I was checking around and my site has completely disappeared from their SERPs, much like it is in Google and Yahoo:(. I was doing a couple of things trying to figure out what has gone wrong, one of them being a “site:” search. I noticed that the index page URL listed is “www.inclaunch.com/?trackcode=bizcom” which it must have gotten from the Business.com directory (hence the bizcom part). I’m almost positive that up until today the index URL was listed properly, "www.inclaunch.com/", and adding the “?trackcode=bizcom” to the URL is responsible for my listings disappearing. Has anybody had any experience with this?
