A few things I can think of:

  • Are cookies being cleared each time testing is iterated?
  • Is the demdex cookie being set on both domains? This cookie is what allows cross-domain tracking using the same mid.
  • Are both domains requesting the mid simultaneously? You might want to try waiting a second or two so the demdex cookie is defined.
  • Is tracking both domains absolutely necessary? Bear in mind that this will double server call volume on these pages, and inflate page views if both calls are s.t().
