Dr. Walter Carl on Measuring Conversations
I recently listened in on a WOMMA Webinar with Dr. Walter Carl, founder and chief research officer at ChatThreads Corp. Walter is a faculty member at Northeastern University and serves as chair of WOMMA’s Measurement & Research Council. (So when it comes to measuring WOM, he knows his stuff.)
Walter shared interesting information on measuring the value of conversations. In one of the more provocative points in the webinar, Walter shared an analysis of a Premium Pet Food word-of-mouth program he was involved with. Part of his analysis included using ChatThread’s Conversation Value® Model to crank out some ROI data.
For programs they work on, Walter’s company has the ability to track person-to-person conversation ripples and then tie those conversations directly back to sales for a straight ROI analysis. From there, ChatThreads also projects a lifetime ROI measurement.

The “advocacy campaign” for a Premium Pet Food brand Walter talked about in the webinar started with an initial 5,000 participants. The initial 5,000 people engaged in conversations with people and then, those people engaged others in conversations about this pet food brand.
So, Wave 1 of this program included an initial 5,000 participants in an “advocacy campaign” for a premium pet food brand.
[Wave 1 total: 5,000 people]
The next ripple, Wave 2, saw the initial 5,000 people each carry on a conversation about this premium pet food brand with, on average, 12 other people. Thus, 61,167 people heard the advocacy message for this pet food.
[Wave 2 total: 61,167 people]
Wave 3 saw these 61,167 people pass along the pet food advocacy message to nearly 3 people each, broadening the reach to an additional 173,101 people.
[Wave 3 total: 173,101]
In total, 239,268 people heard the advocacy message about this premium pet food brand.
[5,000 + 61,167 + 173,101 = 293,268]
It’s important to note, all of the people involved in these conversations were not current customers of this pet food brand. According to the study Walter cites, these were all new potential customers.
Watch/listen to this snippet from Walter Carl’s WOMMA Webinar. Pay special attention beginning at the 4-minute mark of the webinar snippet. This is where Walter breaks down the ROI analysis of this program in two ways: (1) straight ROI and (2) lifetime ROI. The straight ROI for this program was 64% and the lifetime ROI was 220%.
All you research wonks probably have a kagillion counterpoints to make. Go for it. I’ll pass-along your rebuttals to Walter and hopefully, he’ll answer your counterpoints.
