Methods and apparatus to determine an adjustment factor for media impressions

摘要

Examples to determine media impressions are disclosed. An example method includes determining an exposure of first media, wherein the exposure occurs after a cookie identifier is received at a computing device, wherein the cookie identifier is received from a database proprietor, determining a first panelist identifier associated with the exposure based on the cookie identifier, determining a second panelist identifier associated with the exposure based on a determination of a user identity by a panelist meter associated with the computing device, determining an adjustment factor by comparing the first panelist identifier and the second panelist identifier, determining a number of impressions of second media from data logged by the database proprietor, the data logged in response to requests transmitted to the database proprietor in response to clients accessing the second media, and applying the adjustment factor to the number of impressions to determine an adjusted number of impressions.

1. A method comprising:
determining an exposure of first media has occurred, the exposure occurring after a cookie identifier is received at a computing device, the cookie identifier received from a database proprietor; determining, via a processor, a first panelist identifier associated with the exposure based on the cookie identifier; determining, via the processor, a second panelist identifier associated with the exposure based on a determination of a user identity by a panelist meter associated with the computing device; determining, via the processor, an adjustment factor by comparing the first panelist identifier and the second panelist identifier; determining, via the processor, a number of exposures of second media from data logged by the database proprietor, the data logged in response to requests transmitted to the database proprietor in response to clients accessing the second media; and applying the adjustment factor to the number of exposures with the processor to determine an adjusted number of exposures.
