I'm not in the contest, but if I was - I'd be SKEEEEERED. This was awesome, really - there were MAYBE 3 things I knew... The rest was new. I'm lame that way. The great thing about this is that as a blogger - you've covered ideas I've never thought of...I get my traffic mostly from SEO (not on my blog, but in my websites which are product based review sites) - but there's enough meat in this post I can use for my niche sites to keep me in the black, so to speak (ink I mean, not socks). Awesome post, Brankica - I'm speechless. (If you ignore the foregoing paragraph.)
Note the penultimate processing step (previous campaign within timeout), which has a significant impact on the direct channel. Consider a user who discovers your site via organic search, then returns via direct a week later. Both sessions would be attributed to organic search. In fact, campaign data persists for up to six months by default. The key point here is that Google Analytics is already trying to minimize the impact of direct traffic for you.
For a long time, digital marketers summed up the properties of direct and organic traffic pretty similarly and simply. To most, organic traffic consists of visits from search engines, while direct traffic is made up of visits from people entering your company URL into their browser. This explanation, however, is too simplified and leaves most digital marketers short-handed when it comes to completely understanding and gaining insights from web traffic, especially organic and direct sources.
