SERP (Search Engine Results Page)
The page of results a search engine returns for a query.
The SERP is what a searcher sees after hitting enter: a mix of ads, the local pack, featured snippets, AI overviews, and the traditional organic links. Modern SERPs push the classic ten blue links far down, so knowing which features appear for a query, and which you can realistically win, matters as much as raw ranking position.
