I have large volumes of "None" bucket under the Direct and Paid Search Marketing channels within the Last Touch Channel Detail report. While researching this using the raw data feed, I see that the field va_closer_detail carries a value of "::hash::0" in many records which seems to be the ones reported as "None". My "Direct" channel processing rule assigns "pageName" value into the Channel Detail variable. I am assuming va_closer_detail field gets the value from this process rule settings. Does anyone know how it gets the "::hash::0" value ?
From what I've heard, "::hash::0" is caused by special characters that AA can't handle.
Check your tracking codes used with Paid Search for any possible punctuations and/or special characters, i.e. anything that is not alphabets, numbers, hyphens, underscores, pipes, periods/full stops.
