Google Analytics bounce rate isn't useful for single-page applications unless you monitor user activity with JavaScript and GA event tracking. Not everyone is aware of this and/or can do this. We should update the docs with regards to events. GA can do retention reports or "cohort analysis" and show how visitors return in a monthly basis, but there are two critical limitations on it: 1) It doesn't show you which landing pages, target markets, or their combinations are retaining the most. 2) You can only study one metric by the time and not the total retention + conversions each segment generate, which should be the deciding factor There is no initial interest, nor predictions either. So when doing a new campaign you cannot take any insights from cohort analysis until you wait for enough return visitor data. We certainly agree that Google Analytics is an awesome tool and it has served our sites really well in the past. It gives tons of general insights for a free service, but isn't designed specifically for conversion optimization. Hence Volument.
