A Search Engine Results Page (SERP) is the web page displayed by a search engine in response to a user's query. It typically lists links to websites, ads, and other relevant content that matches the search terms entered. SERPs are designed to help users quickly find the most relevant information, and their layout can include organic results, paid advertisements, featured snippets, images, videos, and local listings. The order and type of results shown depend on the search engine's algorithms and the specific query.
