Twitter TV ratings explained: What they measure, what they don't and what it means
Yes, maybe and no. Here's what the Twitter ratings do and don't do.
What they measure: "Nielsen Twitter TV Ratings include both activity and reach metrics for TV-related conversation on Twitter," Deirdre Bannon, VP of product for SocialGuide (which teamed up with Nielsen to collect the Twitter ratings data), tells Zap2it. In other words, they measure bpth the volume of tweets about a given show and the number of Twitter users who see those tweets. Measurement happens three hours before, during and three hours after a show airs. Original tweets and retweets carry the same weight.
The unique audience on Twitter for a given show is "de-duplicated," Bannon says, meaning that if you see tweets from 10 people about "The Walking Dead" -- which tops last week's rankings (see below) -- you're only counted as one member of the show's Twitter audience.
What they don't measure: A couple of things. For starters, Twitter ratings are not added to a show's on-air rating -- they're a "complement" to Nielsen's traditional ratings, not an addition to them, Bannon says.
Twitter ratings also don't measure the number of people on Twitter who are watching Show X, only the extent of its reach within the Twitterverse. As Bannon puts it, "impressions are recorded each time a tweet about a TV show reaches a Twitter user, regardless of whether that user is watching that TV show."
What's the point? We asked Bannon how she expects networks and cable channels will use Twitter ratings. "Nielsen Twitter TV Ratings enable TV networks to measure the full Twitter engagement surrounding their programs including both Twitter TV-specific activity (Authors, Tweets) and reach (Unique Audience, Impressions)," she says. "Having total activity and reach metrics for TV-related conversation on Twitter is valuable in several ways. With NTTR, networks can integrate total Twitter engagement into ad sales strategies. With insight into who was actually reached, networks can also identify true influencers -- the people whose tweets are actually read by large audiences -- and measure effectiveness of Twitter TV engagement strategies. Finally, networks can use Nielsen Twitter TV Ratings to better understand the relationship between Twitter and tune-in."
