1. A method comprising: determining a target geographic feature that has insufficient targeting information associated therewith, wherein the insufficient targeting information is insufficient to provide targeted content associated with the target geographic feature, the target geographic feature defining a location; determining one or more similar geographic features to the target geographic feature, each similar geographic feature including targeting information and defining a different non-overlapping location from the target geographic location, wherein the one or more similar geographic features are determined based at least in part by identifying a geographic feature having one or more excess queries in common with the target geographic feature, wherein each excess query is a query associated with and exceeds an expected query count for each of the one or more similar geographic features and the target geographic feature; attributing targeting information associated with at least one of the one or more similar geographic features to the target geographic feature; and serving content responsive to queries that relate to the target geographic feature based at least in part on the attributed targeting information; wherein for each of the target geographic feature and the one or more similar geographic features, the expected query count associated with the query is computed as a function of a total number of queries received over a time period for the target geographic feature or the one or more similar geographic features and a query share associated with the query; wherein the query share is computed as a ratio of the number of times that the query was received from user devices in a baseline geographic region relative to a total number of queries that have been received from user devices in the baseline geographic region.
16. The method of claim 1 where determining one or more similar geographic features to the target geographic feature includes comparing a number of shared excess queries and a number of dissimilar excess queries for the target geographic feature and a candidate geographic feature.
