If you've been on a link building campaign lately and would like to check on the fruits of your labor (your PageRank) then click over to Rusty Brick's new PageRank predictor.
Type in your url and the predictor estimates what your PageRank will be after the next Google update, and the percentage of its rise or decline.
Barry Schwarz, the tool's builder, wouldn't reveal how it works, but did say that it's only for fun. He wouldn't "bet his house on it."
Thanks to Barry and RustyBrick for the tool.
Any ideas on how it might work?
