When doing key word research i understand that its best to find an exact match domain. But what if the domain is taken and I have to add a couple extra characters at the end. Will that effect much ? like for example my keyword would be "blank blank blank" and the domain would have to be "blank blank blank TX" . In the google keyword tool the first one shows as higher searches and higher cpc and the one with the addition of "tx" at the end is a little lower. how much of an effect will this have when it comes to ranking and conversions ? Should I try to keep the first one and just find a different TLD extension like .info or .net instead of the .com ?
