What is Organic search?

[Jeffreyhooft]

Organic Search is a term used to describe the unpaid or natural search results from the keywords you have entered into a search engine.

[Reginaldutere]

Organic search results are listings on search engine results pages that appear because of their relevance to the search terms, as opposed to their being advertisements.

[Reginaldutere]

“organic search” refers to the natural search engine results that appear for any given query.
These are separate from the “paid search” or “sponsored” search engine results that also appear after each search is processed through the search engine.
