Methods and apparatus to determine media impressions using distributed demographic information

Abstract

Example methods involve based on a first request to log a first media impression, generating a first identifier associated with a first client device that generated the first request, and sending a communication to the first client device. The communication includes the first identifier, and the communication is to cause the first client device to send the first identifier associated with the first client device to a database proprietor in association with a cookie identifier of the first client device. Second media impressions are logged in association with the first identifier of the first client device and second identifiers associated with second client devices based on second requests received from the first and second client devices. A batch including the second media impressions and the first and second identifiers is sent to the database proprietor. Demographic information associated with the second media impressions is received from the database proprietor.

1 . A method to log media impressions, the method comprising:
 based on a first request to log a first media impression:
 generating a first identifier associated with a first client device that generated the first request, and 
 sending a communication to the first client device, the communication having the first identifier, and the communication to cause the first client device to send the first identifier associated with the first client device to a database proprietor in association with a cookie identifier of the first client device; 
   logging second media impressions in association with the first identifier of the first client device and second identifiers associated with second client devices based on second requests received from the first and second client devices;   sending a batch including the second media impressions and the first and second identifiers to the database proprietor; and   receiving demographic information associated with the second media impressions from the database proprietor.   
     
     
         2 . A method as defined in  claim 1 , wherein the first and second requests are hypertext transfer protocol requests that do not return webpages. 
     
     
         3 . A method as defined in  claim 1 , further comprising logging the second media impressions in association with at least one of one or more campaign identifiers, one or more placement identifiers, or one or more creative identifiers associated with advertisements that caused the second requests. 
     
     
         4 . A method as defined in  claim 3 , wherein the batch includes hash values of the at least one of the one or more campaign identifiers, the one or more placement identifiers, or the one or more creative identifiers. 
     
     
         5 . A method as defined in  claim 1 , wherein the sending of the batch to the database proprietor is based on at least one of a threshold of logged impressions or a time threshold. 
     
     
         6 . A method as defined in  claim 1 , wherein the first identifier distinguishes the first client device relative to at least the second client devices. 
     
     
         7 . A method as defined in  claim 1 , wherein the first identifier is located in a payload of the communication. 
     
     
         8 . A method as defined in  claim 1 , wherein the communication includes a uniform resource locator of the database proprietor. 
     
     
         9 . A method as defined in  claim 8 , wherein the communication is a redirect communication or includes instructions to cause the first client device to initiate a second communication with the uniform resource locator of the database proprietor. 
     
     
         10 . An apparatus to log media impressions, the apparatus comprising:
 an identifier generator to generate a first identifier associated with a first client device based on receiving a first request from the first client device to log a first media impression;   a communication interface to send a communication to the first client device, the communication having the first identifier, and the communication to cause the first client device to send the first identifier associated with the first client device to a database proprietor in association with a cookie identifier of the first client device;   an impression logger to log second media impressions in association with the first identifier of the first client device and second identifiers associated with second client devices based on second requests received from the first and second client devices; and   the communication interface further to:
 send the batch including the second media impressions and the first and second identifiers to the database proprietor, and 
 receive demographic information associated with the second media impressions from the database proprietor. 
   
     
     
         11 . An apparatus as defined in  claim 10 , wherein the first and second requests are hypertext transfer protocol requests that do not return webpages. 
     
     
         12 . An apparatus as defined in  claim 10 , wherein the impression logger is further to log the second media impressions in association with at least one of one or more campaign identifiers, one or more placement identifiers, or one or more creative identifiers associated with advertisements that caused the second requests. 
     
     
         13 . An apparatus as defined in  claim 12 , wherein the batch includes hash values of the at least one of the one or more campaign identifiers, the one or more placement identifiers, or the one or more creative identifiers. 
     
     
         14 . An apparatus as defined in  claim 10 , wherein the communication interface is to send the batch to the database proprietor based on at least one of a threshold of logged impressions or a time threshold. 
     
     
         15 . An apparatus as defined in  claim 10 , wherein the first identifier is to distinguish the first client device relative to at least the second client devices. 
     
     
         16 . An apparatus as defined in  claim 10 , wherein the communication interface is to communicate the first identifier as a data parameter of the communication. 
     
     
         17 . An apparatus as defined in  claim 10 , wherein the communication interface is to communicate a uniform resource locator of the database proprietor in the communication. 
     
     
         18 . An apparatus as defined in  claim 17 , wherein the communication is a redirect communication or includes instructions to cause the first client device to initiate a second communication with the uniform resource locator of the database proprietor. 
     
     
         19 . A tangible computer readable medium comprising instructions that, when executed, cause a machine to at least:
 in response to a first request to log a first media impression:
