A method of dynamically formatting visualizations of third-party content by a distributed computing system, the method comprising:

• identifying a presentation opportunity for presentation of third-party content in various locations of a given electronic document presented at a user device;
• evaluating, based on information related to the identified presentation opportunity, a corpus of electronically stored third-party content to identify a set of third-party content eligible to be presented in the given electronic document;
• dynamically generating visualizations of at least some of the various third-party content in the set using formatting that is selected based, at least in part, on a location of the electronic documents that will present the visualization and prominence provided by other locations of the electronic document;
• and
• transmitting, to the user device, machine readable instructions that automatically cause the user device to present at least some of the visualizations of the various third-party content according to respective formatting that was selected for each of the at least some of the various third-party content.

A non-transitory computer storage medium encoded with a computer program, the program comprising instructions that when executed by a distributed computing system cause the distributed computing system to perform operations comprising:

• identifying a presentation opportunity for presentation of third-party content in various locations of a given electronic document presented at a user device;
• evaluating, based on information related to the identified presentation opportunity, a corpus of electronically stored third-party content to identify a set of third-party content eligible to be presented in the given electronic document;
• dynamically generating visualizations of at least some of the various third-party content in the set using formatting that is selected based, at least in part, on a location of the electronic documents that will present the visualization and prominence provided by other locations of the electronic document;
• and
