I plan to setting few "User Generated Content Site" such as social bookmarking site, website directory, article directory site or wiki site with my few unuse domain. I do aware that some automated software out there, will automated submit customer URL to thousand of site (social bookmarking site, website directory, article directory site). How can I insert my website to their list? Any location to promote my URL to them other then approaching them one by one? content wise I not really care much on unique/duplicate. Traffic wise I also not care much whether is bot or automated software submit content to my website or actual human manually submit content to my website. Most important is there is content insert constantly. Other then promoting my website manually over forum, is there any suggestion for better way to get my website more content?
