I have developed a stock discussion forum whereby I separate each forum by the ticker symbol. The issue is, recently, the makers of the Blackberry phone, Research in Motion (formerly ticker symbol RIMM), decided to change their company name to Blackberry (new ticker symbol is BBRY). Because the ticker symbol changed from RIMM to BBRY, I subsequently had to change the structure of my forum from:
http://www.alphabanter.com/forum/rimm
to:
http://www.alphabanter.com/forum/bbry
However, the page http://www.alphabanter.com/forum/rimm used to rank really well in Google. Specifically, if you searched for the term "rimm forum," that page would come up as high as #4 on the first page in the search results (the average ranking for this page was also very high based on the data in Google webmaster). In fact, this page was my best ranking page for my entire website and drew the most visitors.
To preserve my page rank (am I confusing this with keyword rank?) as best as possible, I did a 301 redirect from http://www.alphabanter.com/forum/rimm to http://www.alphabanter.com/forum/bbry. Unfortunately, http://www.alphabanter.com/forum/bbry has very poor ranking in Google. If I search for the term "bbry forum", it does not show up in the search results in Google at all.
Is there a reason why http://www.alphabanter.com/forum/bbry has such a low ranking in Google? I thought the 301 redirect was supposed to preserve my ranking? What should I do next time if a similar situation happens for one of my other forums?
Update: My bbry forum now ranks high in Google now. I changed the title to "Blackberry (BBRY) Stock Discussion Forum" from "Blackberry Forum" (I also changed the Meta description to accompany the title change). I can now find my forum if I search for "bbry forum". Searching for "Blackberry forum" though does not find my forum but that is expected since "Blackberry forum" is a very competitive search term.
