Due to an error in the AdWords tracking (changes by AdWords) around half of the AdWords click was counted with the referrer as "Direct" instead of AdWords. We are very sorry for this and this is now fully fixed as of today 10th of February 2014.
This means that if you were using Redistats and got traffic from AdWords you will now see that the number of referrals from AdWords will go up around 50% to the correct number and the "Direct" referrers will go down with the same amount.
We are also as of today stripping out the gclid parameter. For example:
This URL: http://www.domainname.com/?gclid=3DCsdfgO3SiPi4wbwCFdfdfaHbcgodqEEA1Q
Will now bee seen as: http://www.domainname.com
Again, we are sorry for this.
