Facebook announced last week that the criteria used to determine whether someone is a daily active visitor of its product "Watch" is by measuring whether a users spends at least one minute on the "Watch" platform per day, but Axios has confirmed that those 60 seconds do not need to be consecutive.
Why it matters: In order for Facebook to lure advertisers who typically buy ads on television to purchase video ads on "Watch," it needs to convince them that the social platform's audience is just as engaged with shows on "Watch." But TV networks measure a "view" of a show based on whether a show was watched for 60 consecutive seconds.
Our thought bubble: This doesn't necessarily mean that Facebook doesn't have a handful of very engaged users — it said that its daily visitors to "Watch" spend more than 20 minutes with the service per day — but it means that the measurement criteria is still too opaque for ad buyers at big brands to be able to buy "Watch" ads with the same confidence that they buy TV ads.
The big picture: There's a reason Facebook wants you to believe that "Watch" is pulling in TV-like engagement: It wants to sell TV-like video ads.
