Techniques for storing and retrieving content associated with a specific geographic location include identifying discrete regions included in a bounding region and initializing a list of discrete regions and a count of identified local content. For each identified region: determining a number of content items included in the region; updating the region list with an ID of the identified region if it contains at least one content item; and adding the determined number of content items to the count of identified local content. Deciding whether to proceed to a next identified region includes determining if unprocessed regions remain and if a predetermined content limit was reached. The next region is then processed if there is a next region and the content limit has not been reached. The regions are processed, content IDs for content items associated with processed regions are located in a content database for further selection or serving.
