Hi, let me address your questions one at a time:
- Since these are time buckets for unique visitors, if a user comes to the site and spends 3 minutes, then again later and spends 10 minutes, are they placed in both time buckets?
- Yes, this is correct.. these buckets are based per visit. You can even see this, ID you were to add up all the UVs per bucket, you will get a much higher value than the total for the column, this is because the total de-duplicates the UVs... but for each row, the count of UVs contains any visit by a UV that fell into that time span.
- If a user is on the site and the session "times out" - will that count for two different unique visits in different time buckets?
- Yes, if the user session times out, and they then come back and start loading pages, that will be a new visit with its own time spent (though in theory, if they spent 3 mins, timed out, then came back and spent another 3 mins both visits would fall under the same bucket and the user would only be counted once)
- For the average time on site for each time bucket - is that the average amount of time users spent on that site for a bucketed amount of time, moving the average as we incorporate users who spent more time on the site?
- Honestly, I don't think mixing Average Time on Site and Time Spent per Visit - Bucketed is a good idea.. the numbers look sort of reasonable at the beginning... but as the buckets get larger, the Average Time on Site starts to make no sense....
- All of Adobe's time metrics are calculated, and sometimes mixing them like this can result in some very odd results.....
