What is Dimension in Google Analytics?
Dimensions are attributes of your data.
For example, the City dimension indicates the city from which a user accesses your website. The Page dimension indicates the URL of a page that was viewed by a given user.
Dimensions and metrics help you better understand the behavior of your target audience on your site. They make it possible for you to understand who your clients are, what interests they have, from what channels they come to your site.
By analyzing this data, you can see if you’re on the right track and adjust your goals and marketing budget .
