Hi Martijn,
When you say "Organic campaigns can come from an unpaid search engine results link, a referral from another website (such as a blog) and direct traffic."
I don't get it how a referral or direct can be considered an organic visit. I recreated the report Tim has mentioned and then changed the advanced segments to Referral and Direct to see if I see any figures. If what you say is correct, when I select organic searches as my metric and then select direct traffic in advanced segments - shouldn't I see the organic traffic from direct traffic.
Please let me know
