I've searched for this in vain; please pardon me if this is an old (and repeated) question. In using Digital Point's Keyword Tracker, I get a rank of 3+37 for Yahoo. I'm smart enough to realize what the '3' is, but I don't understand the rest of it. Would one of you good people explain this? Thanks.
Another welcome to DP! To add to what Crazy Rob said it will mean one page on your site is at #3 while another different page on the same site is position 37
No script... not random. Like Rob said it means you have more than one position you rank for. In the example of 3+37 you would rank 3rd & 37th for your keyword.
