Mystery Shopping Scores: Understanding Brand Execution

A mystery shopping score is a weighted performance rating that measures how consistently a business executes its service standards. It combines observations from covert evaluators posing as real customers, into a single score that helps businesses uncover operational gaps, and improve the customer experience.

But what do these scores represent? More importantly, how will mystery shopping results impact how brands plan and execute their operating standards?

Here's a breakdown of what mystery shopping scores mean and how they provide actionable insights for informed decision-making.

What Do Mystery Shopping Scores Measure?

A mystery shopping score might look like a simple percentage, but behind that number is a detailed picture of how consistently a brand delivers on its promises.

For multi-location businesses, scores help answer important questions: Are customers receiving the experience we designed? Which locations are outperforming expectations? Where are operational gaps affecting satisfaction, compliance, or revenue?

These scores are typically compiled from structured questionnaires and evaluate several operational categories that influence customer experience and brand execution, including:

1. Customer Service: Evaluates staff friendliness, wait times, product knowledge, and how quickly customers are acknowledged and assisted.
2. Product Quality: Reviews product availability, presentation, freshness, condition, and whether products meet established brand standards.
3. Operational Efficiency: Assesses speed of service, transaction accuracy, order fulfillment, process execution, and the consistency of operational procedures.
4. Cleanliness and Ambiance: Evaluates the overall appearance and condition of the location, including floors, counters, restrooms, merchandising, signage, and the overall customer-facing environment.
5. Compliance with Protocols: Measures if staff follow company guidelines, safety regulations, promotional offers, and legal protocols (such as ID checks for age-restricted items). 
6. Sales & Brand Behaviors: Rates upselling and cross-selling efforts, loyalty program promotion, recommendation quality, and how effectively employees communicate and reinforce the brand experience.
   
7. Digital Experiences: Scores customer interactions across websites, mobile apps, online ordering platforms, curbside pickup, delivery services, chat support, and other digital touchpoints that influence the overall customer journey.
   

How Are They Scored?

When getting the data for mystery shopping, the results typically include:

• Overall score, representing the overall rating.
• Category, theme, or section scores, breaking down the ratings for different aspects of the customer experience, such as the level of service, cleanliness, friendliness, product quality, speed of service, etc.

Mystery shopping scores are looked at in two ways:

• Individual mystery shop record scores: At the individual level, scores for an individual mystery shop can be used to recognize top performance or identify and resolve deficiencies.  
• Aggregate mystery shop scores: Mystery shopping scores can be aggregated to identify trends or compare results across regions, timeframes, dayparts, or other business attributes.

Case in Point:

Here's an example: For 25 years, our Annual Drive-Thru Study has covered some of the top Quick-Serve Restaurant (QSR) brands, delivering a long history of providing the leading insights into drive-thru performance. 

One of the key areas evaluated is Order Accuracy. As you can see in the chart below, the brands included in the study are attributed an accuracy score based on the number of orders fulfilled accurately in this study. In this case, data is aggregated by brand and compared year over year. 

Not only does this kind of data give actionable insights for the brands involved in the study, but it is also a helpful tool for other brands to use to benchmark their performance against these industry leaders.

How Do You Interpret Mystery Shopping Scores?

Because mystery shopping typically measures execution against a standard, brands expect to see their locations achieving a mystery shopping score of 90% or higher. But what does this score really indicate?

Let's look at the results of the 2025 CSP Intouch Insight Mystery Shop Audit as an example.

This audit evaluates various aspects of convenience stores, including everything from fuel pumps, to food options to employee interactions. The top three brands achieved an overall mystery shopping score above 95%, with the winner scoring 97.62%.

Such a high score demonstrates these brands' commitment not only to store-level execution but to customer service performance, too.

So, where do you start? 

When planning the evaluation criteria for a mystery shopping program, a good starting point is to look for aspects of the business that are underperforming. You can identify these from other sources like customer feedback surveys and online reviews. 

Then, you can use the new found mystery shopping results to understand where operations fail to meet customer expectations. The insights gained can be used to set specific, measurable goals for improvement. 

For example, if scores indicate slow service, a goal might be to reduce wait times by implementing new efficiency measures. If those don't work, leaders can further investigate: 

• Is it a technology problem? (i.e., do they need a new POS system?)
• Is it a resource problem? (i.e., do they need more staff during peak hours?)
• Is it a brand standard problem? (i.e. do they need to revisit the brand standards to better meet customer needs?)

The most effective framework evaluates performance level and guides leaders on action steps.

While grading scales will depend on a company and their objectives, here's an example of a grading criteria:

In terms of some individual operational categories, heres what score interpretations look like:

Product Knowledge

A study conducted by our team on grocery stores showed that 4 out of 5 brands scored over 80% on providing a helpful recommendation, showing room for improvement in this sector. 

Cleanliness

Because things like cleanliness can be subjective, it's important to define the standard you are looking for. For example, in our study of 4 leading coffee chains, cleanliness was defined using the following scale: 

• Excellent: No garbage, floors clean
• Good: Less than 3 pieces of garbage, floors clean
• Fair: Between 4-6 pieces of garbage, floors have no spills

In the case of this study, the overall cleanliness score was 87%, meaning 87% of locations visited had no garbage, and the floors were clean.

Suggestive Selling

The On-Premises Study focusing on in-store counter execution found that the average suggestive sell score across 10 QSR brands was 60.6%, while the leader scored 78.4%. This indicates a benchmark for brands as to what is achievable in this category and how realistic goals can be set. 

Using Mystery Shopping Scores for Brand Improvements

Once you have a clear understanding of the mystery shopping scores, the next step is to use this information to drive improvements. Individual scores can be used to recognize exceptional staff and identify training opportunities, while aggregated scores help companies spot broader trends and fix system-wide issues.

We empower leading brands to establish mystery shopping programs that result in the consistent execution of brand standards across all locations.
