I'm looking in Google Analytics at Audience > Behavior > Frequency & Recency for a property I manage. My histogram looks like this:



Something's fishy. The official docs say I should read this histogram like so:


Analytics counts sessions for this report in the following manner:


User 1 engaged 1 time during the time frame.
User 2 engaged 2 times during the time frame.
User 3 engaged 3 times during the time frame.
The first row of the report (1 session) has a count of 3 (one each for user 1, 2, and 3).
The second row of the report (2 sessions) has count of 2 (one each for user 2 and 3).
The third row of the report (3 sessions) has a count of 1 (one for user 3).


...

Regardless of the time frame, you're likely to see that users who come only once outnumber everyone else.


OK, so I think I see what's happening here. The "Sessions" column in the chart above is actually a count of "users" or "uniques", and therefore this site had 123,649 users during the specified timeframe, and 2,419 users who visited the site 8 times.

But how many visitors visited the site more than 8 times? The buckets beyond the single count of sessions make this tough to read.

Am I reading this right?

"Count of Sessions" is "The number of visitors with X sessions during this time period".

You have far more than 123,649 users during the specified time. You had 123,649 users that visited exactly once (one session) in this time period. You had 2,419 users who visited the site exactly 8 times.

To get the number of visitor who visited more than 8 times, you would have to add up sessions for "Count of Sessions" greater than or equal to 8.

I'm pretty sure that the documentation for how it works is wrong. In the "interpreting the histogram" section they say that user 3 visited 3 times, they would count in each of the first three lines of the graph. If that were true, then the "sessions" number in the first line would be equal to the number of unique visitors for the same time period. Here is the data from one of my sites for a time period:

Count of Sessions Sessions
1 5,100
2 671
3 249
4 105
5 61
6 40
7 24
8 22
9-14 69
15-25 39
26-50 72
51-100 81
101-200 68
201+ 94


Google Analytics reports that me website received 5,546 unique visitors for this time period. If the "Count of Sessions: 1" were "at least 1 session" than the sessions on that line should be 5,546. Instead it is 5,100.

If the "count of sessions" were interpreted as "visitors with at least this number of sessions", you would also expect the sessions reported to be monotonically decreasing. But in your graph and in my data, there are plenty of cases where the "Sessions" is larger than on the line above it.

Of course, I would also expect that sum of all the sessions in the graph should equal the number of unique visitors. But in my case it equals 6,125.
