Hi, thanks for your comment. When you refer to incognito browsing, I think it's important to clarify that referrer data *is* passed between sites. Click on a link whilst in incognito, and the referrer header is passed as usual. The exception is if you're browsing normally, and then opt to open a specific link in incognito mode - this won't pass referrer data.
Incidentally, according to a June 2013 study by Chitika, 9 out of 10 searchers don't go beyond Google's first page of organic search results, a claim often cited by the search engine optimization (SEO) industry to justify optimizing websites for organic search. Organic SEO describes the use of certain strategies or tools to elevate a website's content in the "free" search results.
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.
