I have a site that sells a broad range of related items. I'm going to be developing a new site that sells a specific line that I also sell on my original site. I wanted to know if I should make the domain "private" to avoid possible dup content if any of the se's found out I owned both. The products will be the same but the descriptions will be rewritten. I don't know if this is something that's important or not and thought I better ask b4 getting under way. Does a private listing hurt anything? Are they recommended?
