Hi Friends,

While doing Off page SEO, especially Directory Submissions, URL is not accepted. Most of the directories are shows “please fix this field” or “The URL could not be validated. Either the page does not exist or the server could not be contacted” like this.

What is the reason. Why it happens, Anybody knows?
