What Is Dimension In Google Analytics?

If you use Google Analytics on your website or mobile app, there's a good chance you've seen the label “dimension” quite often. Dimensions are one of the core concepts in Google Analytics and are crucial for making sense of the data you see on your Google Analytics dashboard.

If you're wondering what it is, how it works, and how it fits into your web analytics goals, well, that's exactly what we'll be talking about.

First thing first, let's start with what it means…

What is a Dimension in Google Analytics?

A dimension in Google Analytics is a descriptive attribute or characteristic of your Google Analytics data. It provides context to the metrics by categorizing, labeling, and segmenting data.

Beyond that, let me paint you a picture to really help you understand dimensions.

You are on your Google Analytics dashboard. You are looking at the number of sessions, pageviews, and maybe new users on your site. Now, that's quantitative data – those are the metrics.

Metrics are important, yes. They tell you how much activity is happening on your site. It is basically a quantitative measurement that tells you "how many" or "how much." But to really make the most of that “how many” and “how much” you need to understand the "who," "what," and "where" of that data – and that's where dimensions come in.

Let’s break it down further.

Imagine you see that your blog post about “the best iPhone to buy in 2024” is getting 20,000 pageviews. That’s great! But without additional context, that data is shallow. Dimensions provide this context by telling you more about the "who," "what," and "where" of those page views.

So, in this case, Dimensions would help you answer three key questions about the 20,000 pageviews to your blog post:

• Who are the 20,000 people visiting the blog post? – Using dimensions like 'User Type' (new vs. returning visitors) or 'Device Category' (people visiting from mobile, desktop, tablet).
• What are the 20,000 visitors to the blog post interacting with? – With dimensions such as 'Page Title' or 'Event Category', you can see which specific pages or events are engaging your audience.
• Where are the 20,000 visitors to the blog post coming from? – With Dimensions like 'Source/Medium' you can identify how visitors found your blog post (e.g., organic search, social media), dimensions like 'City' and 'Country' provide geographical data about visitors’ locations.

Of course, Dimensions like ‘User Type,’ and ‘Device Category’ aren’t the only dimensions on Google Analytics. There are quite a number of them.

Key Dimensions in Google Analytics

Google Analytics comes with many built-in dimensions, each offering unique insights into the numbers you see on your Google Analytics dashboard. Here are some of the most commonly used dimensions on Google Analytics:

1. User Dimensions:
   • Location: Country, city, and region of the user.
   • Device Category: Mobile, desktop, or tablet.
   • Browser: The type of web browser used by the visitor.
2. Session Dimensions:
   • Source/Medium: How users arrived at your site (e.g., Google/organic, Direct, Referral).
   • Landing Page: The first page a user views in a session.
   • Session Duration: The time a user spends on your site during a session.
3. Interaction Dimensions:
   • Page Title: The title of the page viewed.
   • Event Category: Categories assigned to user interactions tracked as events, like video plays or downloads.
   • Campaign: The marketing campaign that led the user to the site.

Other terms related to Dimensions you might have come across when dealing with Google Analytics are “Primary” and “Secondary” dimensions. These are basically fancy words to describe the role that a Dimension plays in describing or giving meaning to metrics or reports in Google Analytics. Not clear? Let’s break it down further:

Primary Dimension

The primary dimension is the main attribute by which data is organized in a report. It serves as the starting point for segmenting your data. For example, in a report showing user acquisition, the primary dimension might be "Source/Medium," which indicates where your traffic is coming from, such as organic search, direct visits, or referrals.

Secondary Dimension

The secondary dimension adds another layer of detail to your primary dimension. It allows you to refine your primary dimension even further by adding another attribute. For instance, if "Source/Medium" is your primary dimension, you could add "Landing Page" as a secondary dimension to see which specific pages users land on from different traffic sources.

Example Scenario

Imagine you're analyzing your website traffic, starting with "Source/Medium" as your primary dimension. This shows that organic search is a significant source of your traffic. To gain deeper insights, you add "Landing Page" as a secondary dimension. Now, you can see which specific pages are attracting visitors from organic searches.

From going deeper to a secondary dimension you might discover that your blog page is the most visited landing page from organic search, while your product page gets the most direct visits. This additional layer of detail helps you understand not just where your traffic is coming from, but also what content is resonating with different audience segments.

Google Analytics: Powerful but Complicated

Google Analytics is a powerhouse, but its way of presenting data can be needlessly complicated. One big issue is how it spreads metrics across different pages and reports. Just finding a simple metric like pageviews can feel like navigating a maze of menus and options. This fragmented approach can slow you down, making it harder to perform thorough analyses and get meaningful insights quickly.

This complexity also means you might miss out on crucial information, making it tough to get a clear picture of your website’s performance.

Then there's the issue of data overload. The sheer number of dimensions and metrics available on Google Analytics can be daunting, especially if you're not a seasoned analyst. Often, you don't need most of these metrics, but there's no easy way to find the key ones at a glance. You end up sifting through mountains of data to find what matters, which can be a major obstacle to making effective decisions.
