Welcome to the Q&A Forum

you have an exact match domain first I want to ask you have you been told by Google you've been penalized? if you have not and you're talking about adding it to valid directories of course you can. If they are spam directories something not relevant to your website and would not help the end-user then by all means do not submit. There are a lot of exact match domains out there some of them have gone down some of them are still ranking very high. If you're worried that doing something that you feel is the right thing to do will get you caught then it sounds like you have a guilty conscience but I don't want to guess on that. I would simply check out any directory you are going to submit to and make sure it is something valid like the Yellow Pages. Sincerely, Thomas
