Earlier, we specified what makes a good bounce rate in Universal Analytics. Now, we'll take a closer look at GA4's definition of a "good" bounce rate.
In Universal Analytics, a bounce rate between 41% and 50% was considered average. However, if your bounce rate percentage lands anywhere from 55% to 70% or higher, that's considered high.
Since GA4 now measures engagement, which is inverse to UA's bounce rate, an "average" engagement rate would fall somewhere between 50% to 59%. This means around half of your users are engaging with your site. Conversely, a 30% to 45% engagement rate means most users are leaving your website without staying for more than 10 seconds or taking any other actions.
