Under the Brand Posts tab of the Focus section, the ART for brand responses on proactive content is displayed.
For ART by the brand on User Posts on their Facebook page, head over to the User Posts section under Focus.
Fun fact: If you do a stellar job, they’ll even stamp your Page with a ‘Very Responsive’ badge.
ART on Twitter-
Does your brand hit reply at lightning speed or does it take its time? A brand’s Average Reply Time is the average time it takes a brand to respond to a Tweet from a customer that mentions the brand’s Twitter handle. However, note that the responses are calculated only for original Tweets directed to a brand; this does not include Retweets.
The Focus section of Twitter, has a tab dedicated to Customer Service metrics. Here you will find the graph below for the brand of your selection, consisting of the correlation between when the brand is being mentioned, the frequency of replies at that time, with the ART plotted against it.
