I made the rookie mistake of using a .us url for a website because it was the only way I could get an exact match domain. I now know how to get around that issue. I'm on page 2 of Google with a PR2 and I've spent some time (and money) building backlinks. The site has about 15 pages of good content and all the articles are in the 1,000 word range. Should I kill this site and rebuild with a dot com, net, or org or should l or just keep building on this site. If I kill, will there be any duplicate content issues if a wait a few days before republishing with the same content?. Any other suggestions?
