Methods and systems for detecting home and employment change conversions

Systems and methods for providing conversion metrics for ads related to the housing industry or the employment industry are provided. A system can identify a plurality of ads provided for display to a plurality of identifiers. Each of the plurality of ads is related to one of a housing industry or an employment industry. The system can identify, for an advertiser providing a subset of the identified plurality of ads, one or more identifiers to which the subset of the identified plurality of ads are provided for display. The system can determine, from a location database that includes location information of the plurality of identifiers, a number of identifiers of the identifiers to which the subset of the identified plurality of ads are provided for display that changed locations. The system can then provide, to the advertiser, a conversion metric based on the number of identifiers that changed locations responsive to determining that the number of identifiers is greater than a predetermined threshold.
