See full text

Example methods and apparatus to de-duplicate impression information are disclosed. An example method includes extracting, by executing a first instruction with a processor, characters from first cookies stored in a first memory space, the first cookies collected from client devices via network communications, and in response to the processor determining that at least two of the first cookies (1) include a same pattern of characters, and (2) correspond to a same first demographic, executing a second instruction with the processor to store, in a second memory space, the pattern of characters in association with the first demographic to indicate that the pattern of characters and the first demographic are both representative of a same first unique audience member.
