What is the difference between organic and paid results?
Organic search is based on unpaid, natural rankings determined by search engine algorithms, and can be optimized with various SEO practices. In contrast, paid search allows you to pay to have your website displayed on the search engine results page when someone types in specific keywords or phrases.
Paid search traffic occurs when a visitor clicks on a link in an advertisement or sponsored listing that a business has paid to appear at the top of search results. search results are the Web page listings that most closely match the user's search query based on relevance. Also called "natural" search results, ranking high in the organic results is what SEO is all about.
