As a part of the new encrypted search data I'm seeing one of my sites top referring keywords as "(not set)", this is annoying as it's a massive percentage of referral traffic and have a number of campaigns running. It's looking more and more like Google is gearing up for their paid analytics will give you this data but the free system will provide inaccurate data. Biggest annoyance is how this is something they're taking away - not just refusing to add. anyone else noticing this with any of their site's referring keyword data?
Yes this is now common for most sites, apparently 10% of all organic traffic will show as 'not set' for the foreseeable future...makes you wonder
