I had great results with Stumble Upon cause I have been a user for years and Stumble a lot of things that have nothing to do with blogging or my blog. And Networked blogs is working great for me too :) I am glad you found some new sources here. I would love, if you had the time, to look into one or two that seam interesting to you, and maybe try them out... and then come back and tell me if they worked OK 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.
