Techniques are described herein for optimizing the presentation of content through obtaining viewership metrics, generating multiple renditions of presentations of content, and selecting optimized renditions of content. One aspect includes associating a request for viewership metrics with a presentation of content, publishing the presentation of content, and receiving information of the viewership metrics associated with the presentation. Another aspect includes copying a presentation of a content item, creating a second presentation of the content item for publishing over one or more channels, and linking the presentation of the content item to the second presentation of the content item, such that a change to one propagates to the other of the presentation of the content item or the second presentation of the content item. In yet another aspect, a content rendition may be selected for presentation based on performance of the rendition out of multiple renditions in an auction.
