Abstract: Methods, systems, and apparatuses are described herein for managing an optimizing advertising content placement, rendering third party advertising tags, and tracking analytics associated with third party advertising content. The tag management system is a publisher-side platform for native and recommended content that enables publishers to manage their relationships with native advertising partners and optimize their placement of native ads. The global ad tag may detect a location within a HyperText Markup Language (HTML) document, wherein the location is associated with placement of advertising content. A script associated with the advertising content may then be loaded at that location on the HTML document. Analytics associated with the advertising content may then be tracked, and the analytics associated with the advertising content may be reported to a server running the tag management system.
