AT&T’s Greg Pharo, who heads marketing analytics, recently joined Ed Keller for a webinar and shared the results of AT&T’s market mix modeling, revealing the significant role that WOM plays in driving new customer acquisition.
Pharo reported that paid advertising plays the biggest role in bringing new customers to the fold, accounting for 30% of “gross adds” or sales. Word of mouth is a close second, explaining over 10% of sales volume through positive comments, plus over 10% of lost/unrealized sales volume due to negative comments.
What about other metrics sometimes used by brands as a surrogate for word of mouth? “We’ve tried other metrics besides Word of Mouth, such as online buzz (social media) and NPS (the Net Promoter Score),” said Pharo. “While they provide some insights, they aren’t as strong or reliable for explaining sales as word of mouth.”
In conclusion, Pharo told the audience, “Word of Mouth is an impactful, relevant variable for influencing sales in the wireless category. WOM metrics belong on a CMO dashboard as a key performance indicator.”
