the only way to check is to go to the "who is" and most times it wont say as the person whom bought the got the domain Private, Registration. The only other way would be to check the "sites IP address" and that may give you a clue but again its not for sure that you will get the correct answer. While our directories are USA based we no longer offer free submits in any of ours as the amount of spam we received from china, pakistan, india, and others was just to over-welming for our editors and not worth the time fixing the constant errors and spam filled titles & descriptions that are submitted, and that traffic never converts to any sales and also seems to discourage US & UK submissions so unfortunately we cant offer FREE. thx malcolm
Qassia recently glocalized their web directory into national versions, so what you want is us.qassia.com where the "us" stands for United States. Disclosure: I work for Qassia
Visit this link. They have huge list of free directory. http://www.directorycritic.com/free-directory-list.html
If you were after US regional directories (directories that specifically only accept sites from the USA) then feel free to PM me. If you were indeed after US based directories then the advice of the other posters rings true, and most of them probably are on US servers anyways.
No Going to keep addurl-links.com free as i was so disgusted yesterday when another editor coudnt do the editing and when i seen that mess i was mad to say the least, But when i thought about its not everyone that is at fault and only a few so it will remain FREE and we will just have to keep deleting the garbage submissions and banning IPs from those that cant follow the rules. thx malcolm
