I have a question about the background colour of the links in SEI. Does this mean the link was successfully submitted if it's green, or is it something to do with the nofollow/follow status? What about yellow and grey? Looks like the nofollow/dofollow status - in which case, is there a way we can tell if a site has been submitted at all? Or does it mean every link that appears has been submitted? I am trying to find a way to see how many are submitted vs indexed.
