Understanding Dimensions in Google Analytics

Posted by

Google Analytics is a powerful tool that provides valuable insights into website traffic and user behavior. However, navigating through its various features and metrics can be overwhelming, especially for beginners.

One of the most important concepts to understand in Google Analytics is dimensions.

Dimensions are attributes of your website visitors and their behavior that you can use to analyze your data. They provide context to your metrics and help you understand the who, what, when, where, and how of your website traffic.

Some common dimensions in Google Analytics include location, device type, traffic source, and user demographics.

By understanding dimensions in Google Analytics, you can gain deeper insights into your website’s performance and make data-driven decisions to improve user experience and drive conversions.

In this article, we will explore the basics of dimensions in Google Analytics and how to use them effectively to gain valuable insights into your website traffic.

Fundamentals of Google Analytics Dimensions

Defining Dimensions and Metrics

In Google Analytics, dimensions and metrics are the building blocks of data analysis. A dimension is a descriptive attribute or characteristic of an object that can be measured, while a metric is a quantitative measurement of that dimension.

In simpler terms, dimensions are the “what” and metrics are the “how much”.

For example, if you have an ecommerce website, the dimension “Product” could be used to describe the type of product being sold, while the metric “Revenue” would measure how much money was earned from selling that product.

Types of Dimensions in Google Analytics

Google Analytics offers several types of dimensions, each providing a unique perspective on user behavior.

  • Hit-level Dimensions: These dimensions are associated with each individual interaction with your website, such as a pageview or event. Examples include “Page Title” and “Event Category”.
  • Session-level Dimensions: These dimensions are associated with a user’s entire session on your website, from the moment they arrive to the moment they leave. Examples include “Source/Medium” and “Device Category”.
  • User-level Dimensions: These dimensions are associated with a user’s overall behavior on your website, regardless of the number of sessions they have had. Examples include “Age” and “Gender”.
  • Product-level Dimensions: These dimensions are associated with ecommerce transactions and provide information about the products being sold. Examples include “Product SKU” and “Product Category”.

By understanding the different types of dimensions available in Google Analytics, you can gain deeper insights into user behavior and make more informed decisions about your website.

Implementing Dimensions

Setting Up Custom Dimensions

To implement custom dimensions in Google Analytics, the user must first create a new dimension in the “Admin” section of their Google Analytics account.

From there, they must specify the scope of the dimension (user-level, session-level, or hit-level) and provide a name for the dimension.

Once the dimension has been created, the user must update their tracking code to include the new dimension.

This can be done by modifying the ga() function in the tracking code to include the dimension name and the value to be tracked.

Custom dimensions can only track data going forward, so it is recommended to set up dimensions as soon as possible to ensure that all necessary data is being collected.

Best Practices for Naming and Structuring

When creating custom dimensions, it is important to follow best practices for naming and structuring.

This includes using clear and concise names that accurately describe the data being tracked.

Additionally, it is recommended to use a consistent naming convention for dimensions across all properties to ensure consistency and ease of use.

This can be achieved by using a standardized naming convention, such as using a prefix or suffix to indicate the type of dimension being tracked.

Finally, it is important to consider the scope of the dimension when structuring it.

User-level dimensions should be used for data that remains constant across multiple sessions, while session-level and hit-level dimensions should be used for data that varies within a session or hit.

Analyzing Data with Dimensions

Google Analytics provides a wide range of dimensions to help users analyze their website data. Dimensions are attributes of website visitors or their interactions with the website, such as age, gender, location, device type, and more.

In this section, we will discuss how to analyze data with dimensions in Google Analytics.

Segmentation and Comparison

Dimensions can be used to segment and compare data in Google Analytics.

Segmentation allows users to divide their data into smaller subsets based on specific criteria or dimensions. For example, users can segment their data by age, gender, location, device type, traffic source, and more.

By doing so, users can analyze the behavior and performance of different segments and identify trends and patterns.

Comparison allows users to compare data between different segments or dimensions.

For example, users can compare the bounce rate of mobile and desktop visitors, the conversion rate of visitors from different traffic sources, or the revenue generated by visitors from different countries.

By doing so, users can identify the best-performing segments and optimize their website accordingly.

Understanding Reports and Dashboards

Dimensions are used in various reports and dashboards in Google Analytics.

For example, the Audience Overview report provides data on the number of sessions, users, pageviews, bounce rate, and more, segmented by dimensions such as age, gender, and location.

The Behavior Flow report provides data on the path that visitors take on the website, segmented by dimensions such as traffic source, landing page, and device type.

Dashboards allow users to create customized reports that include specific dimensions and metrics.

Users can create dashboards for various purposes, such as monitoring website performance, tracking marketing campaigns, or analyzing user behavior.

By using dimensions in dashboards, users can create more targeted and insightful reports that help them make data-driven decisions.

Advanced Dimension Usage

Google Analytics offers a variety of dimensions that can be used to gain insights into website traffic. However, the true power of dimensions lies in their ability to be integrated with goals and events, as well as leveraged for audience targeting.

Integrating Dimensions with Goals and Events

By integrating dimensions with goals and events, website owners can gain a deeper understanding of user behavior.

For example, by tracking the dimension of “source/medium” alongside a goal of “form submissions,” website owners can determine which traffic sources are driving the most valuable conversions.

Similarly, by tracking the dimension of “product name” alongside an event of “add to cart,” website owners can gain insights into which products are most popular among users and adjust their marketing strategies accordingly.

Leveraging Dimensions for Audience Targeting

Dimensions can also be used for audience targeting, allowing website owners to create highly targeted advertising campaigns.

For example, by targeting users who have previously viewed a specific product or category, website owners can increase the likelihood of conversions.

Additionally, by targeting users based on demographic or geographic dimensions, website owners can ensure that their advertising efforts are reaching the most relevant audience.
