“Chartbeat monitors activity by checking in with users every second and looking for signals (mouse movement, key strokes, etc) that show they are actively consuming the content in front of them. This means they can measure how long readers spend actively engaged on a page and what parts they’re reading. Because of this Chartbeat knows how long are actively reading while an ad is in view — both for an average user and the cumulative time of all users.” Chartbeat then did some internal research that found high correlation between engaged time exposed and a user’s ability to recall the advertiser’s brand and message.
