I am in the process of doing research on building content for some state to state transactions.   Through our PPC ad history I can see people have searched relatively evenly for full state names versus state abbreviations.  Texas vs TX or California vs. CA.  If I do a google search for one of our key terms with the state abbreviation, it seems that google returns results with the full state name and bolds the full state name in the meta description even though only the abbreviation, and not the full state name was part of the search.  I guess I'm trying to figure out if its worth me building out and targeting two sets of content...one around the full state names and one around the state abbreviations. Any advice?
