In some embodiments, a content placement system selects and allocates content objects for a display region in a user interface based on content priorities of the content objects and location priorities of virtual locations in the display region. The content placement system receives a request for content objects to be presented in the display region. The content placement system determines a layout for dividing the display region into multiple virtual locations. Each of the virtual locations contains spots each configured for displaying a content object. The content placement system determines content objects and allocation of the content objects for each of the virtual locations based on content priorities associated with the content objects and location priorities of the virtual locations. The content placement system transmits the content objects according to the allocation to an online platform for display in the user interface.
