A user who is browsing the internet sees Google Adwords display ad for laptop computers on a Google Display Network site, but does not click on the ad. Two weeks later, the user is interested in buying a laptop computer and decides to visit the site from the ad. The user finds the site by performing a Google search, goes directly to the site, and purchases a laptop. Implementing view-through conversions would be valuable for the advertiser because it could:
A) track the IP addresses of the users who saw the ad
B) measure the number of conversions that are associated with ad impressions
C) track the number of users who saw the ad but did not convert
D) measure the number of potential clicks that are associated with ad impressions
