One of the reasons for a traffic drop can also be due to your site losing links. You may be seeing a direct loss of that referral traffic, but there could also be indirect effects. When your site loses inbound links, it tells Google that your site isn't as authoritative anymore, which leads to lower search rankings that in turn lead to traffic drops (because fewer people are finding your site if it's not ranked as highly and more).
Hi Matt, realizing now how difficult it is to run a blog, trying to promote it and carry on with your daily activities. I would say it's a full time job. Once you thing you done learning about something, something else is coming :). My blog is about preparing for an ironman so I need to add the training on top of it. Thanks a lot for sharing this article with us so we can keep focus!!!
The "Direct Session" dimension, not to be confused with the default channel grouping or source dimension, is something different. It can tell you if a session was genuinely from its reported campaign (reported as No), or if it was simply bucketed there due to the last non-direct click attribution model (reported as Yes). I didn't mention this dimension in the article because it has some flaws which can cause brain bending complexities, plus it goes a little beyond the scope of this article, which I tried to gear more towards marketers and non-expert GA users. It's certainly an interesting one, though.
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.
