What are sessions in Google Analytics?

Sessions in Google Analytics are a group of interactions a user has with your website within a given timeframe. A session is like a container for a series of user interactions such as pageviews, events, and transactions.

How is a session measured?

A session begins when a user who is not currently participating in an existing session arrives on your site. A session ends in one of several ways:


If a user is inactive — meaning they don’t interact with your site — for 30 minutes, the session ends.

Thirty minutes is the default length of time, but you can adjust this time to anywhere from one minute to four hours. Every time a user interacts with your site, they extend the current session by another 30 minutes or whichever amount of time you choose.

Date change

Sessions end at midnight, even if a user is still actively engaging with your site. If a session ends for this reason, a new session immediately starts.

If, for example, a user arrives at your website at 11:55 p.m. and leaves your website at 12:05 a.m., Google Analytics will record two sessions. The first session ends at 11:59:59 p.m., and the second session starts at 12:00 a.m.

the next day. Your time zone settings in Google Analytics determine when a day begins and ends.

Campaign change

If a user arrives at your site via a campaign, leaves, and then comes back via a different campaign, the original session ends, and a new one begins. Every time the campaign source changes, Google Analytics starts a new session.

Campaigns include various sources such as Google Ads campaigns, organic search results, and referrals from links on other websites. So, for example, if a user arrives at your site via an organic search result and then clicks on an ad and opens another page on your site, Google Analytics will end the original session and start a new one. The exception to this rule is direct traffic, which includes traffic from users who typed a URL directly into their browser address bar.

If a user who is currently in a session interacts with your site via a direct source, Google Analytics won’t start a new session.

How to view sessions in Google Analytics

To check how many sessions your website had during a given period, go to “Audience” in the left sidebar in Google Analytics and click “Overview.” Sessions is one of the default metrics that appear on the Audience Overview page. You can adjust the dates for the data you’re looking at in the top right corner of the screen. Sessions in Google Analytics

Why and how to track Google Analytics sessions

Sessions tells you roughly how many times users visited and interacted with your site.

This information gives you a rough idea of how popular and how engaging your site is to users. What really makes sessions data important is how it intersects with other metrics in Google Analytics. Here are a few examples.


For example, you can compare your sessions during different periods.

This will give you insights into trends related to the number of people interacting with your site over time. You can find out, for instance, if your sessions increased or decreased throughout the year. You can also compare session data on various dates to determine when people interact with your site most.

For example, do you see more interaction on weekends or weekdays? During which months of the year are users most active on your site?

Campaigns and sources

It’s also useful to look at which sources and campaigns drove the most sessions on your site. This gives you insight into how successful your campaigns are and which traffic sources are currently most important for your site.


If you run an ecommerce site, you can use sessions to learn more about how users shop on your site.

If you go to “Conversions,” then “Ecommerce,” and then “Shopping Behavior” in Google Analytics, you can see how many sessions included important actions like viewing products, adding items to a cart, and completing transactions. For example, if your site has fewer completed transactions than interactions in which a user clicks the checkout button, you might want to look at your checkout process. Perhaps you need to optimize your process to make it faster and easier or add more payment options.

Comparing sessions to other Google Analytics metrics

Let’s look at how sessions compare to some other closely related metrics in Google Analytics to help you get a better understanding of how you can use your sessions data.

Google Analytics sessions vs. users

Users in Google Analytics is a measure of the number of unique visitors your site gets. One user could have several sessions. If a user visits your site, clicks around for a few minutes, and leaves, they completed their first session.

If that same user returns later that day and does the same things again, they complete their second session of the day. So, Google Analytics would record one user and two sessions. In theory, each user Google Analytics counts is unique.

In reality, the technology isn’t perfect, and the platform might count one person as two users if, for instance, they visit your site using two different devices.

Google Analytics sessions vs. new users

Google Analytics also records a metric called new users. This metric only includes users who visited your site for the first time. If a user returns to your site, they will count as a user but not a new user.

Google Analytics accomplishes this by assigning a unique identifier to each user.

Google Analytics sessions vs. pageviews

Google Analytics records a pageview every time a page is loaded or reloaded. ‘Pageviews’ measures the total number of pages viewed. So, a session can contain multiple pageviews.

If a user visits your website and views five pages on your site during a single session, Google Analytics will record one session and five pageviews.
