Alexa used to provide a semi-accurate representation of my website's traffic. In June I was ranked around 25,000. Since then my traffic has only increased (dramatically), and my Alexa chart has been on an insanely steep decline (getting worse every day - http://www.alexa.com/data/details/traffic_details/keepbusy.net). I'm now ranked 62,000 although my traffic has since doubled! Quantcast and Google Analytics show my site on a steep incline (http://www.quantcast.com/keepbusy.net). TribalFusion and other ad networks have told me I can join their premier networks when my page rank falls within the top 40,000 - so Alexa is killing me right now. Any ideas why it's showing the exact opposite traffic results? I'm hoping it's a coincidence, but it started killing me as soon as I added the Quantcast tag to my page - I know they are rivals - any chance Alexa could be sabotaging sites that use Quantcast? Any ideas how to turn things around?
