What is the unique user (UU number) of Google Analytics?

Do you know how many users use your website?

This section explains in detail the meaning of Google Analytics unique users (UUs), how to use Google Analytics to check unique users (UUs) on each page, and the differences from PVs and sessions.

1. What is the number of UUs in Google Analytics?

Google Analytics unique users (UUs), as the name implies, show how many people viewed the page .
For example, if 500 users viewed the page during the period, the number of UUs will be "500". The number of times a user views the page is independent of the number of UUs. Even if one user has viewed the page 10 times, the UU count will still be "500".

Thus, regardless of the user's usage tendency, the number representing the number of pure website users is the UU number.

However, it should be noted that if one user is viewing the page on multiple devices (PC and smartphone, etc.), the number of UUs will be counted separately.

The "Users" and "Active users" metrics show the number of users who viewed or interacted with your site or app.

2. Number of UU and number of PV

The number of PVs (number of page views) indicates the number of times the page was loaded.

A page view is when the page is loaded (reloaded) into the browser. Pageviews is a metric defined as the total number of pages viewed.

Difference between the number of PV and the number of UU in Google Analytics

In the example above, Mr. A browsed pages A → B → C in order. At this time, the number of PV is "3", but the number of UU is "1".

3. Number of UUs and number of sessions

The number of sessions refers to the number of times a series of flows from a search or advertisement entering a website to exiting the website.

The amount of time users interact with your site or app. If a user does not perform any action for more than 30 minutes, subsequent actions are considered new sessions. If a user leaves your site within 30 minutes and returns to the same site, it will be treated as the same session.

In the example above, the number of sessions is "3" and the number of UUs is "2".

4. How to check UU number with Google Analytics

Google Analytics uses the term "user" to represent UU numbers.
There are two ways to determine the number of UUs in Google Analytics, and the method of checking depends on the "what" UU number you want to know.

① If you want to check the number of UUs on the entire site

After logging in to Google Analytics,

1. Click [Audience> Summary] to display the user summary.
2. [UU number of whole website] can be confirmed
3. You can select the data period from the select box at the top right

② If you want to check the number of UUs on each page (need to set custom report)

1. Click [Custom> Custom Report]
2. Select [New Custom Report] to move to the custom report creation screen
Google Analytics Custom Report Creation Screen
3. Click [Add Metric]
4. Select [Frequently Used Dimensions and Metrics> Users] or [Other Dimensions> Users> Users]
5. Click Add Dimension
6. Select [Frequently Used Dimensions and Metrics> Page] or [Other Dimensions> Behavior> Page]
7. Click [Save]
Create a custom report that checks the number of users per page by specifying the user as the metric and the page as the dimension in Google Analytics
8. The created custom report is displayed
The number of UUs per page was confirmed in the custom report of Google Analytics

In this way, Google Analytics needs to create a custom report to check the number of UUs per page.

5. Access analysis tool "Anatomy" to visualize UU number

The access analysis tool "Anatomy" that visualizes Google Analytics allows you to check the number of UUs not only by URL but also by screen capture.

In Anatomy, you can display the number of UUs on each page simply by clicking (①) on the “UU” at the top of the panoramic view. You do not need to create custom reports as you do with Google Analytics.

In addition, tiles representing each page are color-coded in four levels according to the number of UUs, so you can see at a glance how large or small the number of UUs on the site are (②).

Also, you can check the transition graph of the number of UUs per page simply by clicking the icon on the graph on the right (③).

With the access analysis tool "Anatomy", changes in the number of UUs and users per page can be easily checked

In this way, "Anatomy" is a tool that allows you to easily check the number of UUs on each page, the design of the page, the distribution of UUs throughout the site, and the transition of the number of UUs per page .


UUs are an indispensable indicator of access analysis along with inflows and PVs, because a high number of website users indicates a large number of conversion opportunities. However, if you find it a little annoying to use Google Analytics, try "Anatomy" once.

If you have any concerns about Google Analytics settings, such as not being able to measure the number of UUs on a particular page, a service that can diagnose the settings of Google Analytics is also included.
