Say I have an opportunity to get another link from a high authority site that has already linked an important article from me (a page I REALLY want to rank well). Now a month later, they are interviewing me and asking what I'd like to link. I have plenty of good content I can offer, but I really want that page they already linked to to climb a bit in the rankings.
So my question is, how is that second link best spent? Would linking to the same page give it a boost? Or does Google see it as "oh. Another link from the same domain. Yippee."
Would that link do more for a different page on my site at this point?
