Engagement rate shows the share of sessions that stick, not just click. Google Analytics 4 counts a visit as engaged when it lasts longer than 10 seconds, fires a conversion event or views at least two pages, so the metric filters out idle bounces.
Engagement rate tells me, in one clean figure, how many visits to my site actually turned into real attention. Google Analytics 4 works it out by dividing engaged sessions by total sessions. A session counts as “engaged” when it lasts longer than 10 seconds, fires a key event or reaches two or more page views, so the rate rises only when visitors stick around and do something useful.
Traffic volume on its own flatters. An ad can flood the dashboard with sessions that bounce instantly and never return. Engagement rate strips out that noise and shows whether the people I paid or worked to attract actually read, click and explore. A steady climb in this percentage tells me the message–market fit is tightening; a slump flags broken pages, irrelevant keywords or careless ad targeting before revenue feels the drop.
I watch the metric in three places. First, by landing page to spot which articles and campaigns pull visitors into deeper journeys. Second, by traffic source so I can cut spend on low-engagement channels. Third, in A/B tests as a quick sense-check before waiting for conversion data to reach significance. When the rate improves I double-check that the uplift carries through to downstream metrics rather than masking a tracking glitch.
Compare the number week on week and investigate any swing larger than 5 percentage points. Segment by country, device and new versus returning users to uncover patterns. Pair it with average engagement time to see whether sessions merely scrape past the 10-second threshold or truly dwell. Remember that engagement rate is the inverse of bounce rate, so if you prefer the old metric just subtract the figure from 100%.
One caution: small sample sizes make the percentage jump around, especially on new pages. Give low-traffic segments a month before drawing conclusions. And while GA4 lets you change the 10-second rule, I leave it at the default so my numbers stay comparable to industry benchmarks. When the percentage edges up, the compound effect flows through every later stage of the funnel without extra ad spend or head-count.
