Users in Google Analytics, also known as unique visitors, is an invaluable tool for measuring, tracking and understanding a site’s audience.
The official Google Analytics definition of this Web metric is: “Unique Visitors is the number of unduplicated (counted only once) visitors to your website over the course of a specified time period.”
The new user definition is: “Users that have had at least one session within the selected date range. Includes both new and returning users.”
Tracking this number monthly is an industry standard for understanding if a site’s audience is increasing, decreasing or staying even.
How to Find the Number
In Analytics, click on Audience in the top left of the page and then on Overview.
The graph at the top will show visits (not users / unique visitors) over the last 30 days. Visits is the number of times a user or unique visitor comes to a site.
For example, if the site has 10,000 users and 20,000 visits, it means that on average the users visited the site twice a month.
The user / unique visitor number is found below the graph in the list between Sessions (which used to be called Visits) and Page Views.
Right below the Overview tab, click on Sessions and change it to Users to see its graph appear at the top of the page in place of the Visits graph.
What the Number Really Means
I have often thought that Google displays the Sessions / Visits chart first because it thinks visits are more important than unique visitors.
One possible reason is that the unique visitor number is not always what it appears to be.
The number is calculated by using browser cookies and other means.
- A single person can use a computer at work and then at home. He or she will be counted as two unique visitors via cookies but be only one person.
- A family of four people can all use the same computer. The computer will be counted as one unique visitor when in fact four people are using it.
- Someone manually clears their cookies. They may be treated as two unique visitors because of two sets of cookies.
It is not surprising that Google seems to place more importance on visits than unique visitors.
That said, the unique visitor number is an industry metric and does provide a useful way of tracking site audience.
Just use it carefully, work to increase the total and understand its limitations.
Demographics, System, Mobile and Language
This section lies underneath the graphical report and numbers that dominate the top of the report.
Note that clicking on some of these reports will display numbers for sessions / visits instead of users / unique visitors.
Sites with a local audience will find the ability to drill down to individual cities, while anyone with an international audience can drill down by country. The language report provides similar results.
The same information is available under Audience / Geo / Location report.
The system reports may be the least used, while the mobile report has useful information about the screen resolution that aids in a mobile-friendly site design.
Mobile Versus Desktop
The rapid rise of mobile means it is becoming important for analysts to track the split between mobile and desktop users. Google Analytics makes that possible with the above report, but it offers other options for analysis.
Look above the graphic at the top of the main audience report page and to the right for something that says + Add Segment. Click on it and select Mobile Traffic (or any other category that looks interesting) and then click on Apply.
The resulting graphic and numbers underneath will show mobile traffic as a proportion of the total traffic. The breakout includes not only users but also sessions and page views.
Sites with a commitment to mobile will want to use this report to track progress in growing total mobile audience, which should outpace desktop growth over time.
