A trending search in our data for "myocardial infarction" shows how Google has piled up its products at the top. It returned:
Google's dictionary definition.
A "people also ask" box that expanded to answer related questions without leaving the search results page.
A "knowledge panel," which is an abridged encyclopedia entry with various links.
And a "related conditions" carousel leading to various new Google searches for other diseases.
All of these appeared before search results by WebMD, Harvard University, and Medscape. In fact, a user would have to scroll nearly halfway down the page—about 42 percent—before reaching the first "organic" result in that search.
