What is "organic" search and how can it help your company?

The first time I heard the term "organic search" I immediately thought of organic food at the grocery store. So, is this organic search healthier for me? Will it reduce my chances of getting cancer? Not only can the search engines bring most of the world's knowledge to my desktop, but now they can prevent deadly diseases too! Imagine my disappointment when I learned organic search was simply the next new buzzword for the concept of pure, or crawler-based search. As some of our readers may find it challenging to keep up with all of the latest lingo, I thought I'd take a moment to at least explain the concept of organic search.
Organic describes a search that returns results by indexing pages based on content and keyword relevancy. This is in contrast to listings ranked based on who paid the most money to appear at the top such as those on Overture.com. Sometimes this is called "pure" or "natural search" as it is supposed to be "untainted" by commercial payments or bids.
Historically, Google has led the way in championing the virtues of natural or organic search. Its primary focus has always been to return fast, highly relevant results based on the content of the page, the relevancy of links pointing to that page, and other "objective" criteria. Sponsored listings have always been clearly separated from the organic search results on Google. However, many other engines have experimented with mixing the two types of search without clearly labeling which is which. This has been followed by public outcries, and at least one cautionary set of statements issued by the FTC in 2002.
