Forget about Google Page Rank, SER.com has said that the PageRank metric has been taken out of Google Webmaster Tools, because webmasters emphasize on it, even after emphasizing that Page Rank is not important. Quotes Susan Moskwa, Google Webmaster Trends Analyst “We’ve been telling people for a long time that they shouldn’t focus on PageRank so much; many site owners seem to think it’s the most important metric for them to track, which is simply not true. We removed it because we felt it was silly to tell people not to think about it, but then to show them the data, implying that they should look at it.“

Though we have become habituated to Page Rank, you can just use it to find if your site is behaving well in Google Index
