While organic search has the advantage of being free and can be influenced by your website content, it is limited to the number of people searching for your business or the products and services you offer. Paid search advertising allows you to reach a broader target audience which has more potential customers who may not be aware of your business, all while providing you full control over your messaging and costs.
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.

You control the cost of search engine marketing and pay nothing for your ad to simply appear on the search engine. You are charged only if someone clicks on your ad, and only up to the amount that you agreed to for that click. That’s why SEM is also known as pay per click (PPC), because you only get charged for each click that your ad generates. No click? No charge.
Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
