Dimensions Explained
Definition: A dimension in Google Analytics is a way to segment and organize data based on certain characteristics or attributes. A Dimension in Google Analytics is simply a data attribute used in conjunction with metrics to provide a more comprehensive understanding of a website’s performance. For example, by viewing the metric of bounce rate through the dimension of the landing page, e-commerce merchants can better understand which pages are leading users to further explore their website.
Examples of Google Analytics Dimensions:
- Campaign: Allows tracking of specific campaigns that led a user to the website
- Source: Identifies the origin of the user before landing on the website (e.g., Google, social media, referral)
- Medium: Specifies the type of referral (e.g., organic search, CPC)
- Device Category: Indicates the device used by the user to access the website (e.g., desktop, mobile, or tablet)
- Gender: Allows segmenting data based on the gender of users
- Ad Content: Allows understanding of which specific ad content led to conversions
- Keyword: Allows understanding which keywords were used in the search queries that led the user to the website
- Day of the Week: Allows understanding the trend of visitors on different days of the week
- Month of the Year: Allows understanding of the trend of visitors in different months of the year
How Dimensions and Metrics Go Together
For example, using the dimension of “source” allows you to segment your data by where the traffic is coming from (e.g., Google, social media, referral), while the metric of “sessions” gives you the number of sessions from each source. Together, these two pieces of information allow you to understand not only where your traffic is coming from but also how much traffic is coming from each source.

FAQ
In GA4, every report includes a primary dimension that is pre-selected to offer a broad understanding of how that dimension performs in relation to a set of metrics. To add more depth to the analysis, Google also allows for the option to segment the dimension data by adding a ‘Secondary Dimension.’ This gives the flexibility to analyze the primary dimension and then view the related data through the lens of a secondary dimension within the same report.
