Hi Lynn, WOW another well written and informative post. I only use PPC to make sure my copy converts, otherwise I use organic traffic only. I have printed off this post and will have by my computer, as another tool to read everyday to make sure I am keeping on track. You are 1 of 3 people I keep subscribed to, because you help, you keep me motivated, you tell it like it is. You give great content, which is a lesson for us all to remember, it is OK to drive traffic to your site, but if you do not have what the seeker wants, then they leave, giving you a horrendous bounce rate and no conversions.
For example, we have seen retailers who produce seasonal items, such as ornaments, based upon data that they are able to find through the Data Cube. This information tells them about the themes and ideas that are popular throughout the year and during their peak selling seasons, helping them to know which items will be the most successful and the optimal names to select.
Most organic sales (93 percent) take place through conventional and natural food supermarkets and chains, according to the Organic Trade Association (OTA). OTA estimates the remaining 7 percent of U.S. organic food sales occur through farmers' markets, foodservice, and marketing channels other than retail stores. One of the most striking differences between conventional and organic food marketing is the use of direct markets—Cornell University estimates that only about 1.6 percent of U.S. fresh produce sales are through direct sales. The number of farmers' markets in the United States has grown steadily from 1,755 markets in 1994, when USDA began to track them, to over 8,144 in 2013. Participating farmers are responding to heightened demand for locally grown organic product. A USDA survey of market managers. ERS research found that demand for organic products was strong or moderate in most of the farmers' markets surveyed around the country, and that managers felt more organic farmers were needed to meet consumer demand in many States. See the ERS report for more on this topic:

Although it may have changed slightly since BrightEdge published its report last year, the data still seem to hold true. Organic is simply better for delivering relevant traffic. The only channel that performs better in some capacities is paid search ads, but that is only for conversions, not overall traffic delivery (Paid Search only accounted for 10 percent of overall total traffic).
