Definition of Natural Search Results
Natural search results are those listings that appear at the discretion of the search engines and that do not incur a charge to the listed site. In most search engines, these are the "main" results. There are frequently ads near the natural results for which advertisers are charged either each time someone clicks on them (PPC) or for each impression.
