Read Rand's post on the blog about diversity in traffic source http://www.seomoz.org/blog/traffic-source-diversity-is-essential-for-successful-seo. I would be very interested to know from mozzers, how their experience has been with traffic share. While you answer, please be kind enough to share the following: 1. The niche of the website you wish to quote in your answer. 2. The means of promotion you use (SEO, Social Media, PPC, Display, Affiliate) 3. The reason you think you cited this example and do you think it has been a success or a failure or somewhere in the middle? Appreciate your time, thanks.
