Google Analytics - Dimensions & Metrics


Google Analytics - Dimensios and Metrics
 IN  BY 


Google Analytics is a platform that collects data and organizes this data into useful reports. By obtaining Google Analytics Individual Qualification certificate, I have learned that Google Analytics allows you to track the performance of your website traffic (or websites through cross-domain function) and provides you with insightful reports.  

I would definitely recommend to set up Google Analytics to your website if you want to:
  • track your conversion and business goal completions
  • find out which campaigns bring the most traffic and conversions to your website
  • determine the location of your best visitors
  • visualize what people click on the most
  • learn what people are searching for on your website
  • identify your best and worst performing pages
  • determine on which step in conversion path people are leaving
  • discover if you need a mobile application or site
  • differentiate new and returning visitors
  • know the source/medium of your traffic
  • understand who your customer are
  • engage people with your content
  • see how key metrics are fluctuating

I believe that it should be enough to encourage you to go to Google Analytics Academy and take GA for Beginners course. So, you can feel confident and comfortable while interacting with this platform.
But before you start I want you to understand what the dimensions & metrics in Google Analytics are.

Every report in Google Analytics consists of dimensions and related metrics. In order to easier understand the definitions of both, I want to provide a short overview on dimensions and metrics, as well as share some examples on what they represent in Google Analytics.

Dimensions

Dimensions are attributes of data. For example, let's say a woman aged between 25-34 years from Toronto visited your website after clicking on a paid search ad, which she found by searching for a keyword "Machine learning courses" via Google Chrome browser. Let's assume that this browser is installed on her mobile device with operation system IOS.

So in this case our dimensions would be as highlighted below:

Gender - Female
Age - 25-34
City - Toronto
Source/Medium - Google/Paid Search
Keyword - Machine learning courses
Browser - Google Chrome
Device Category - mobile
Operating System - IOS

In other words, dimensions are characteristics of your website users.

Metrics

Metrics are numbers in a data set often paired with dimensions. To be more precise, metric is used to measure a characteristic of a dimension. In Google Analytics a metric is presented as a total, average, or ratio of values.

It is noteworthy that not every metric can be combined with every dimension. The data makes sense only when the dimension scope matches the metric scope.

In the example below, I have provided some metrics and what they represent in Google Analytics: 
  •      “Sessions” are the total number of sessions in the given period of time. 
  •      “Users” are the total number of users that visited your website.
  •      “Pageviews” are the total number of views of a page that are being tracked by the Google Analytics tracking code.
  •      “Pages per session” is the average number of pages viewed during each session.
  •      “Average session duration” is the average length of a session based on your site's visitors during a particular period of time.
  •      “Bounce rate” is the percentage of users who left your website after viewing a single page without any interactions.
  •      “Percent of new sessions” is the percent of total users who have visited your website for the first time in the selected date range.

hope that this post will bring you more clarity on what metrics and dimensions are in Google Analytics. However, if you want to see more examples and clarifications on this topic, please visit Google Analytics Help
