Engaged sessions in Google Analytics 4

Source: Analytics Help, Engagement rate and bounce rate.

The 10 seconds are engagement time: the page has to be on screen and in focus. A tab left open behind another one does not run the clock.

The 10 seconds are a setting. You can raise the timer up to 60 seconds in the web stream's tag settings. A longer timer makes fewer sessions qualify, with no change in your traffic.

Engaged sessions are the numerator of the engagement rate. The sessions left over are what GA4 calls bounces.

Versus engagements in Google Ads

Google Ads also has Engagements, and the name misleads. Google Ads counts actions on the ad itself, such as expanding a Lightbox ad or watching a video ad, before anyone reaches your site. An engaged session happens on your site, after the click. Read Google Ads engagement rate for the ad-side figure.

Worked example

A law firm has 2,400 sessions in April and 1,150 engaged sessions. In May a colleague raises the timer to 30 seconds. Traffic stays at about 2,400 sessions, but engaged sessions drop to 820.

Nothing on the site got worse. The rule changed. A drop like this, on the day of a settings change, is the first thing to rule out before blaming ads or pages.

1. In Google Analytics, open Reports, then Acquisition, then Traffic acquisition. Engaged sessions is one of the default columns.
2. In Reports, then Engagement, then Pages and screens, you can add it per page through Customize report.
3. To see or change the timer, open Admin, Data streams, your web stream, Configure tag settings, Adjust session timeout, then the timer for engaged sessions.

Engaged sessions is under Site traffic in Add a metric. It is a count, and higher is better.

Because it is a count, it can carry a goal a month under Other goals on the Goals page. A team that wants 1,500 engaged visits a month sets that number, and its card shows the month against it.

The figure is Google Analytics' own total for the days asked, read when the card is drawn and kept 30 minutes. Optizads does not rebuild it from stored days.

For the engaged share of ad traffic only, use Engaged visits from ads, which reads the same rule on the visits whose source is google / cpc.

• Marking page_view or a scroll event as a key event. Every session that fires it becomes engaged, and the count stops meaning anything.
• Raising the timer and comparing with the months before the change.
• Reading an engaged session as a lead. It is a sign of attention, not a result.
• Expecting long single-page reads to fail. A visitor who reads one article for two minutes is engaged by the time rule.

• Key event: Google Analytics 4's name for an event you mark as important, such as a purchase or a sign-up.
• Landing page: The page people reach after clicking an ad.

• Engagement rate (GA4): Engagement rate in Google Analytics 4 is the share of sessions that were engaged: engaged sessions divided by sessions.
• Bounce rate (GA4): Bounce rate in Google Analytics 4 is the share of sessions that were not engaged: 10 seconds or less, one page or screen, and no key event.
• Sessions (GA4): A session in Google Analytics 4 is one visit to your site or app, opened by the session_start event.
• Ad engagement rate: Engagement rate in Google Ads is engagements divided by impressions: how often people engage with an ad after it is shown.
