Atlas: Average Cookie Lifespan 45 Days
Emphasizing a disparity between user responses to cookie deletion and their actual behavior, an Atlas Solutions white paper released Monday found that
respondents who claimed to delete their cookies weekly, actually had an average cookie "lifespan" of 45 days. In the white paper, Young-Bean Song, author and director of analytics at Atlas, said he
believed that "a more complete study which incorporates actual user behavior is a much better way to formulate a true picture of what's going on."
