The inverted pyramid
Borrowed from journalism, the inverted pyramid puts the most important information first, followed by supporting details, then background context. Online readers are ruthless scanners – many will only read the first paragraph. Give them the essential message immediately, so that every reader gets the core point regardless of where they stop reading. This structure is ideal for web pages, news-style content, press releases and any format where attention is scarce.
