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.
Google measures average time on site by first collecting each visitor’s exact time on a particular page. Imagine that a visitor lands on page 1 of your site. Google places a cookie, including a unique code for the visitor and a time stamp. When that visitor clicks through to page 2 of your site, Google again notes the time, and then subtracts the time that the visitor arrived at page 2 from the time that the visitor arrived at page 1. Google then averages each and every page’s time spent to get the average time each visitor spends on the site.
Amber Kemmis is the VP of Client Services at SmartBug Media. Having a psychology background in the marketing world has its perks, especially with inbound marketing. My past studies in human behavior and psychology have led me to strongly believe that traditional ad marketing only turns prospects away, and advertising spend never puts the right message in front of the right person at the right time. Thus, resulting in wasted marketing efforts and investment. I'm determined to help each and every one of our clients attract and retain new customers in a delightful and helpful way that leads to sustainable revenue growth. Read more articles by Amber Kemmis.
I'm a IT Technician that has decided to take my knowledge of computer repair and maintenance online. So I made a blog about 2 months ago and I'm getting a small trickle of traffic a week. Most of those are from Yahoo! Answers. Twitter I just started using a few days ago and haven't got many followers yet. So It may not be the fastest methods but it's slowly working for me. I just need that surge of constant traffic flow. Thanks for the advice
Traffic data is a great way to take the temperature of your website and marketing initiatives. When you are writing and promoting blog content on a regular basis, you can use traffic data to track results and correlate these efforts to actual ROI. Be sure to look at traffic numbers over long-term intervals to see trends and report on improvement over time.  
Mobile traffic: In the Groupon experiment mentioned above, Groupon found that both browser and device matter in web analytics’ ability to track organic traffic. Although desktops using common browsers saw a smaller impact from the test (10-20 percent), mobile devices saw a 50 percent drop in direct traffic when the site was de-indexed. In short, as mobile users grow, we are likely to see direct traffic rise even more from organic search traffic.
