The organic search results are the results of a search on an Internet search engine (such as Google, Yahoo! or Bing) which are there as a result of their relevance to the keyword searched as opposed to due to advertising or other controlled purpose.
Some historic surveys indicated that users had difficulty determining which results they were viewing were advertisements and which were the real listings. All the major search engines reserve the top positions on their results pages for paid search listings as a consequence as this is an extremely lucrative purpose. Those who do not wish to pay the search providers for a position in their listings can only hope for the top of the organic results no matter how high the quality of their site. Unfortunately for those sites the amount of space taken up on popular search engines such as Google by paid search or other Google instigated widgets has increased considerably and this has had an impact on the value of organic listings – albeit that value is still extremely high.
