When I'm reviewing the sources of my pages within Analytics, I'm occasionally seeing some values that appear to be incorrect/impossible. I'm not seeing it often, but definitely enough to skew some reports unless I add to my filter.
I'm seeing a couple development sites that I'm working on (which have no relation to the production site that I'm viewing reports for) as sources for traffic to the site. These development sites have 0 links to the production site, so I'm not sure how Analytics is seeing them as sources of traffic in any way. There are times when I have both the production site and these development sites open in separate tabs on the same browser, but that's about the closest they are to connecting in any way.
Any ideas on how this could occur?
