Google is updating backlinks for two of its datacenter (64.233.187.104 and 64.233.187.99). They maybe testing their Page Rank algorithm or just preparing for a Page Rank update (I’m not sure). Backlinks for Tech-Buzz.net jumped from 0 to 514 !!.
What does Backlinks mean to you ?
Your Page Rank is determined by the number of backlinks you got. Higher the backlinks, higher is your pagerank.
Google updates its pagerank once in a Quarter. Last time Page Rank was updated somewhere around mid July. I reckon there is 15 - 20 days left to go before the next Page Rank update.
So this is the right time to build links. If you need some Link Building tips, read this

Normally the Page Rank Predition tools are inaccurate. Google takes some weeks to assign the Page Rank to a page and these tools give an answer in a few seconds. For example, for a page that has increased the number of backlinks from 420 to 4300 the prediction is to pass from Page Rank 6 to Page Rank 5.
