Of the different analytic metrics for digital marketing such as per per click, average order value, or clickthrough rate, one important metric to consider is Attention Time.
"The more ‘Attention Time’, the more pronounced the awareness outcome. In one campaign that featured in the research, awareness moved from 30% for consumers with an attention time of under 10 seconds to 52% for 10-20 seconds, and 67% for more than 20 seconds. In real terms, this means that the chance of achieving a lift in awareness increased by 11% for each additional second of ‘Attention Time’ achieved."
