Engine context variables are distinct data points with assorted values. Each context variable (for example, device type) is a piece of information about your customers that the Personalization engine uses when it makes one-to-one decisions. The values of each context variable directly influence the engine and the results you can achieve.
Context variables can contain numerical, categorical, or true/false (Boolean) values. Be mindful of the number of context variables you select and the number of values associated with each selected context variable. Reducing the variable and value counts while maintaining informative context can facilitate faster learning and improve interpretability. Consider how the data can influence machine learning decisions for your customers and less as rules and segments.
The table below describes the types of data that context variables support.
|Data Type||Possible Values||Usage Example||Level of Measurement|
|Numeric||Integer or real number||Relative score, significant only for creating a ranking, such as a customer lifetime value or visit duration||Ordinal scale|
|Categorical||1, 2, K||Categorical outcome, such as device type, browser, or brand affinity||Nominal scale|
|True/false (Boolean)||0, 1||Binary outcome—yes/no or true/false—such as loyalty member or VIP customer||Nominal scale|

Custom Context Variables
Monetate offers additional context variables to supplement the recommended ones. If you decide to expand beyond the recommended set, ensure you can articulate a compelling story about why the custom context helps match certain visitors to one experience variant rather than another.
|Product Type (New Catalog Spec) Purchased in Past 30 Days||Products||True/false||Considers up to 10 product categories purchased by a visitor in the past 30 days, including current session|

You can configure context settings within Monetate at both the account level and the experience level.
Configuring Account-Level Context Settings
To access account-level context settings, select Engine Context from the platform settings menu.
Adjust the context configurations for your account on the Engine Context page. These settings automatically apply to any new Automated Personalization experiences. The number of context variables currently enabled for your account appears at the top of the screen.
Your aim is not to select the most variables. Selecting context variables requires discipline because many factors can impact learning time for an Automated Personalization experience. As a general rule, the more context you select, the longer it may take for the engine to learn and optimize. The engine looks for patterns across your selected context to assign the best-fit variant to each customer to optimize your goal metric.
Configuring Experience-Level Context
When you select Automated Personalization for a Web experience you're building, the engine copies the current account-level context configuration into the experience. You can configure the engine context for each Automated Personalization experience in the HOW settings.
When the mouse pointer hovers over Context Variables in the Engine Context counter, a list of all the context variables in use for the experience appear in a modal.
To add or remove context variables specifically for this experience, either click EDIT that appears beside the Engine Context heading, or click one of the context variables that appears in the modal. Each action has the same result: All the engine context options load on the screen so that you can edit them without leaving the HOW settings.
Click to select or remove context variables as necessary for the Web experience. If you need to reset the changes to the Account Context default, click RESET TO ACCOUNT DEFAULT.
Once you finish editing the context variables, click SAVE.
Some context variables in Monetate contain specific technical details. Read on to ensure you have a more complete understanding of engine context and how each context variable may affect the way the engine makes decisions.
Time of Day
Based on a 24-hour clock using the time zone of the visitor and segmented as follows:
This variable uses the user agent string of the visitor's device to determine desktop, mobile, tablet, or other device type.
This variable uses the user agent string of the visitor's device to determine the Web browser.
This variable uses the user agent string of the visitor's device to determine the operating system.
This variable is determined by a visitor's IP address.
This variable uses the visitor's IP address to determine in which of the nine geographic regions of the US the visitor is located.
This variable looks for the presence of a Monetate cookie to determine if the visitor is returning to the site after a previous visit.
Median Household Income
This variable currently covers the US and the European Union. It is standardized across the data source for each respective region. Through using the same standardization process for both regions, the engine can learn and evaluate visitors from different countries and currencies within one context variable. All US demographic context is based on data from 2020 US Census, and all EU demographic context is based on data from Eurostat.
This variable currently covers the US and the European Union. It is expressed in the number of individuals per square kilometer, allowing the engine to learn and evaluate visitors from different countries within one context variable. All US demographic context is based on data from 2020 US Census, and all EU demographic context is based on data from Eurostat.
This variable considers if a greater than 0% chance of precipitation of any kind is forecast for the next 48-hour interval, including sleet, freezing rain, rain, and snow.
Forecast High & Low Temperatures
This variable considers the forecasted high and low temperatures for the next 48-hour interval are bucketed into the following categories:
|Category||Temperature in Fahrenheit||Temperature in Celsius|
|Freezing||Less than 32º||Less than 0º|
|Cool||32º to 60º||0º to 15.5556º|
|Warm||60º to 80º||15.5556º to 26.6667º|
|Hot||Greater than 80º||Greater than 26.6667º|
This variable considers the time from when the visitor's session started to when the visitor made a decision.
Number of Page Views
This variable considers the number of page views from session start to decision time.
Number of Products in Cart
This variable considers the number of products in the cart from session start to decision time. If a visitor previously abandoned the cart, the engine still considers the cart quantity.
Number of Products Viewed
This variable considers the number of products viewed from session start to decision time.
Amount in Cart
This variable considers the amount in cart from session start to decision time. If a visitor previously abandoned the cart, the engine still considers the cart value.
