SERP stands for Search Engine Results Page. It refers to the page that a search engine displays after a user enters a query. The SERP shows a list of results that the search engine believes are most relevant to the query, which can include organic listings (web pages), paid ads, featured snippets, images, videos, local results, and more.
The content displayed on a SERP is influenced by factors like the search engine's algorithms, the user's location, search history, and the type of query. SERPs are constantly evolving with new features like rich snippets, knowledge panels, and quick answers, all aimed at providing users with the most useful information in the most accessible format.
