Misunderstood: Session Duration in Google Analytics

Google Analytics is a great free tool to get a better understanding of what happens on your website. Once you have the tracking code on your site, you can start analysing the data to improve your website.

In this article, we’re gonna dig a bit deeper in understanding a key metric in your Google Analytics account: session duration. This metric is often misunderstood, which can let you interpret the data differently and make the wrong decisions.

What is session duration?

First let’s explain what this metric represents: The time on site metric is close to what you think it is. It measures the time a visitor spends on your site.

Attached to this metric is the avg. session duration and the avg. time on page metrics, they work in the same way, so in this article, we tackle these as well.

How Google Analytics tracks a visit

The Google Analytics tracking code gets loaded every time a visitor lands on a page of the website. So let’s say a visitor visits 3 pages on the site before it leaves the site:

He spends 3 minutes and 22 seconds on the first page;

1 minute and 8 seconds on the second;

44 seconds on the third page;

After that, he leaves the site.

Google Analytics is not able to see how long the visitor stayed on the third page, as the Google Analytics tracking code doesn’t get loaded after this page.

So even though the visitor stayed 5 minutes and 14 seconds on the site, the session duration in Google Analytics is tracked as 4 minutes and 30 seconds (excluding the 44 seconds of the third page).

Help, my page has a low average time on the page and a high bounce rate

A low average time on the page is not necessarily a bad thing.

For example, if you’re using a typical SEM (search engine marketing) landing page that is built around 1 goal it’s normal that a large portion of your visitors only visits one page.

Also, blog articles often have a low time on page and a high bounce rate. (Your bounce rate is the percentage of visitors that leave after just visiting one page). Visitors often find the information they need on these pages and then leave without taking action.

Keep in mind that a low average time on page or a high bounce rate it doesn’t necessarily mean that the visitor didn’t read the page. Google just didn’t register the actual time that they’ve spent on the page.
