Items within a store do not exist within a vacuum. There are correlations both subtle and overt between various products within a section but also between their placement, reach, and visibility. Understanding these dynamics is essential for any section manager to make effective decisions.
But in order to capture both the subtle and overt correlation between products in each section, we must first be able to track them. After which we can convert this raw data into meaningful information that gives a breakdown of what exactly is happening within a given section.
Products correlations
This is where we come in. Thanks to our technology we can extract valuable information about the performance of the different categories. We simplify all that raw data into different subsets.
Let’s take a grocery store that utilizes our system as a simple case study. For convenience let’s call it “Jay’s Grocery store”. You have your fresh fruits and vegetable sections, your meat and poultry sections, and the various other things you would expect to find in a normal grocery store. If we analyze the Fruit and Vegetable section, we will find the following information:
Example of category analysis from a shopper point of view similar to e-commerce analysis such as Google Analytics
- Visitors. 49.83% of total visitors have passed by this section within a given time frame (usually a business day).
- Dwell time. This is the average time visitors spend in the section, starting from the moment they enter the section until they exit it. In the case of the Fruit and Vegetable section, customers spend 1 min. 45s. interacting with the category.
- Bounce rate. This is the percentage of visitors who have spent less than a certain time (normally 10 seconds) in the section. The image above tells us that 6.44% of customers have had no interaction with the Fruit and Vegetable section.
- Engagement. Percentage of visitors who have stayed more than a certain time in the section. This, however, comes with a caveat. We must bear in mind that this duration is highly dependent on the type of business and customers. For example, the engagement for customers at a grocery store would be lower than that for a furniture store. This is because shoppers spend less time deciding what food to buy, whereas furniture shopping requires a long decision-making process with customers usually coming back repeatedly to view a particular piece before making a choice. Given that in the example we are talking about the Fruit and Vegetable section of a grocery store, the engagement rate shows that 81.17% of the customers have spent more than 10s interacting with the section.
- Engagement dwell time. This is the average time visitors spend in the section once they have been engaged. In simple terms, the time starts when a visitor interacts with a product within the section until they move on. This can be triggered by them pausing at certain points or picking up items. For our example, the engagement dwell time is 2 min. 07s.
In addition to this data, we can obtain information about the top correlated sections, which are those that are usually visited during the same shopping journey. Thanks to this, we will be able to see the bigger picture of the section. As you would expect from a grocery store, some items are more popular than others depending on the season, but to find out how each section interact and relate to each other is where the analytics comes in.

Top 3 categories related to Produce in the store as part of the products correlations
Following our previous example, we have selected the Fruit and Vegetable category to obtain the metrics related to this section. If we take a look at the top correlated sections, we will see that 69.9% of customers who visited the Fruit and Vegetable section took a trip over to the meat category also, all within the same shopping journey. In the case of beer, 44.5% of customers visited this section as well, and 39.9% of total visitors spent a considerable time at the yogurt/cream section.
For any category manager, this is critical information. Not only will they be able to launch effective cross-promotions, but also manage their categories according to shoppers’ insights. It’s a simple concept. If I know that the more time visitors spend in my category, the more money they will spend, I will try to attract their attention and make them spend as much time as possible.
All this information is gathered thanks to the correlation matrix. This is important because it measures the probability of a shopper stopping at a certain category assuming that they already stopped at any other section of the store. If you can predict where next a shopper will go based on where they have been, you can make adequate preparations and increase sales.
