Hi NITESH PATEL - Has your query been answered or would you like to define exactly what you're trying to do?
That's how SCN bookmarks work: it's not like a browser bookmark and can only bookmark content on SCN, where the bookmark link appears.
If you want to keep track of links, you may create a document in your space and list them there. This would be like a reference document. I've done something like this for myself that serves as a personal homepage on SCN and contains my quicklinks/text: Jason Lax's Homepage
