They are also used by our reporting system to estimate the total reach of an ad campaign, as well as frequency of display. This allows advertisers to determine with greater accuracy the composition of the audience they reach. Cookies are also used to sequence the delivery of a series of ads to a web browser, and to limit the number of times a web browser receives any one advertisement.
