Explain what is SERP?

SERP stands for Search Engine Results Page, or Search Engine Results Page, and refers to the list of websites that a search engine returns in response to the keywords of the search. The results usually include a list of websites with their titles, links to the sites and a short description showing where the search matches the content of the page.

Search engines can show three types of results: lists of sites that have been indexed by search engine spiders, lists indexed directly by people and lists of links that paid to appear in search results. There is also search for images, maps, news, and blogs.
