SMITH BRAIN TRUST — Social media users post millions of “likes” and comments every year on brand pages for everything from AAA to Zyrtec. That’s a potentially rich source of information for marketers trying to gauge customer sentiment, but built-in biases create challenges. New research from professor Wendy W. Moe and a colleague at the University of Maryland’s Robert H. Smith School of Business shows how to scrub the data and produce reliable scores.
Moe and her co-author, Smith School professor Kunpeng Zhang, base their brand favorability measure on an analysis of 7 billion Facebook “likes” and comments from 170 million users across more than 3,000 company pages. They then compare results to traditional brand tracking surveys and find a strong correlation.
“This provides validation that our brand favorability score is an accurate and unbiased measure of the brand,” the authors write in a working paper. The key to filtering out social media noise is to account for biases related to user traits, community size and brand type.
Most users who express opinions in online communities tend to lean negative or positive, which can skew results in one direction or the other. To adjust for potential bias, Moe and Zhang look at user behavior across brands. Negative comments mean less when coming from unhappy customers who frequently trash other brands, while positive comments mean less when coming from habitual cheerleaders.
Community size also matters. Smaller, more homogenous communities tend to reinforce positive opinions, creating an echo chamber effect. “The smaller your community, the more positive the bias,” Moe says. “And the larger your community, the more negative the bias.”
Marketers must also account for brand type. Commercial brands tend to attract more negativity than other types. “One explanation is that people who follow celebrities, sports teams, nonprofit organizations and other special interests may be ‘super fans’ and unlikely to provide negative feedback,” Moe says.
