Organic search results are results in Google or any other search engine that achieve their placements naturally. It is done using keywords, linking, and simply having relevant content. This means that there is no payment involved.
Google AdWords and its equivalents do not help much to increase the amount of clicks a link can get despite appearing at the very top of the page. Because of this, small businesses are on more even ground with big businesses than one might think.
Thus, the best way to rank highly in organic search results is to have a well-structured webpage that fits all the requirements of Google’s search engine algorithm.
