As of this release we change the calculation for page duration & session duration, so that you get even more precise data.

Until now, the page duration was calculated by comparing the timestamps of a page and its subsequent page. The difference between the two timestamps is page duration. For the session duration, the same logic is applied to all pages during a session. For the last page of a session, a constant value was being used (30 seconds by default).

With this new release, the actions and media requests are taken into account when calculating the session duration and the page duration of the previous page. Instead of just adding a constant value, event and media requests on the previous page are being used to calculate the last page duration.


Please be aware that an additional constant value is still being added by default (30 seconds by default).


Example


PageDuration (sec.)Comment
1180

Time between Page 1 and Page 2: 10:00:00 -> 10:03:00

2120

Time between Page 2 and Page 3: 10:03:00 -> 10:05:00

3150

Time between Page 3 and Action 5 plus the additional constant value: 10:05:00 -> 10:07:00 + 30

The constant value to be added can be configured per account. Default = 30s.

As of this release we have improved our iPhone device detection: the device recognition process now also takes into account the screen resolution specified by the pixel if the detected device is a generic iPhone.

In practice, this means that iPhone models that have the same resolution will be grouped from now on. In your analyses, you will see all models in the same screen resolution grouped.

Please note that we will not make any retrospective updates to the data (as we do not have any information on this), so the analyses dated before the launch date will still be the same as before and will not show any improvement. Only analyses that have subsequent periods (as the rollout date) should have this grouping.
