A Search Engine Results Page (SERP) is the page displayed by a search engine in response to a user's query. It lists the web pages, images, videos, and other types of content that the search engine considers most relevant to the search terms entered. The SERP is where users find the links to websites and other resources related to their search.
Synonyms: Search Engine Results Page, Search Results Page, SERP

The SERP is crucial because it determines which websites get visibility and traffic from search engines like Google. Ranking higher on the SERP means more clicks and potential customers, making it a key focus for SEO strategies.
When a user enters a query, the search engine uses complex algorithms to evaluate and rank pages based on relevance, quality, and user experience. The SERP then displays these results, often including ads, featured snippets, local listings, and other rich results.
