A recent article in the Wall Street Journal focused on the increasing role the “Net Promoter Score” has had in corporate earning calls and proxy filings. The article mentions executives from leading brands such as Delta, Best Buy, Target and United Health Care, referencing their score and often citing it as proof that consumers preferred that brand over another.

The Journal describes top CEOs as becoming “obsessed” with net promoter score and using the score for executive compensation, operations initiatives and product development.

The problem, according to both the Journal and our analysts at TDn2K™, is that net promoter scores don’t correlate to sales performance or revenue. Additionally, they can be significantly skewed by consumers and employees.

Net Promoter Score (NPS) is typically generated through a one-question survey at check-out in the store, or via email or web site. “On a scale of 1 to 10, how likely are you to recommend the company’s product or service to a friend?”

Of the 150 NPS mentions the Journal tracked on earnings calls, not one executive ever mentioned their NPS score declining. It always went up. The problem with increasing NPS is that there is no proof of any correlation to growth.

“The science behind NPS is bad,” said Timothy Keiningham, a marketing professor at St. John’s University. “When people change their net promoter score, that has almost no relationship to how they divide their spending.”

 

Finding the Right Metric

Hence, if NPS is flawed, what can executives use to measure the guest experience and guest feedback against sales performance? Through White Box Social Intelligence™, TDn2K has developed a robust metric – called Net Sentiment Score – that can be correlated to sales performance and is currently being used by 32 leading restaurant brands (over 5,500 units) to help drive their strategy.

Net Sentiment Score measures a restaurant brand’s social media comments and reviews and classifies them as positive or negative using a proprietary Natural Language Processing, designed by TDn2K specifically for the restaurant industry. Unlike traditional surveys and net promoter scores, Net Sentiment is not prompted or incentivized. There’s no sweepstakes entry or free appetizer for participating. We’re listening to what your guests are saying online authentically – their unsolicited feedback of your brand and their experience as they share it with their friends and social circle (read Connecting Social Media Mentions to Business Results).

To calculate the Net Sentiment Score, we subtract the percentage of negative online mentions from the percentage of positive online mentions for a brand. These mentions are pulled from major social media channels and review sites, such as Facebook, Twitter and TripAdvisor and can also include feedback gathered from online surveys.

 

Positive Mentions – Negative Mentions = Net Sentiment Score

40.47% – 10.29% = 30.18%

 

By pairing this social feedback with robust sales and traffic benchmarking data from Black Box Intelligence™, TDn2K connects the dots between your guest feedback and your sales and traffic performance.

Truth in Numbers

In 2018, our top performing brands averaged 3.2 percent sales growth and 0.9 percent traffic growth. Those brands also averaged a Net Sentiment Score of +41 for service and more specifically the term “experience” mentioned by their guests.

On the flip side, our bottom quartile performers averaged -4.0 percent sales growth and -6 percent traffic decline. And only a +25 Net sentiment score for Service and Experience. That’s a 16-point difference in guest sentiment and more importantly, a 7.2 percent difference in comp sales and 6.9 percent difference in comp traffic.

This gap continues when we look at Net Sentiment for accuracy, appearance and attentiveness.

Bridge the Gap with Meaningful Metrics

Thankfully, TDn2K has a solution to ensure that no restaurant brand ends up referenced in a Wall Street Journal article about meaningless metrics.
