Unique application identification (UAID) stamping for automated classification of an implicit query as an application intent query from web results for enabling improved delivery of applications as a search result is provided. An application indexing engine identifies web resources related to an app, and tags the resources with a unique application identifier associated with the app. Accordingly, an implicit query where a web resource responsive to the query is related to the app triggers classification of the query as an app-intent query, enabling the app to be provided as an app result in response to the query. The app is presented to a user, who may selectively download the app.
