What is SERP?
Search engine results page is a web page shown as a result of a search engine after issuing a search query. It displays the best matches for the searched term.
SERP provides you with a basic summary of each article that has been found. This summary contains the title of the webpage and a few sentences about the page's content. It also shows the keywords matching the search query in bold.
There are two types of results on a search engine results page: organic and sponsored. Organic results are the one found by the search engine and matching the keywords. Sponsored results do not depend on the search query and serve as an advertisement for companies who bought them.
