organic
adj.— «What we refer to as “organic” first page results (un-paid-for results on search engines for chosen key words) is impossible to achieve by conventional means because to be seen, your Web site must stand out among many millions of similar pages.» —“Online Marketing: The Rules about Following the Rules” by Israel Rothman RisMedia.com Mar. 9, 2005.
