Filters vs. segments
I am reaching out you regarding discrepancies on figures depending on whether I use GA segments or chart filters in Datastudio. The segment and the filter are based on a custom dimension.
Here are the figures:
Total number of sessions for this view in GA: 2,208,320
Total number of sessions for this view in Datastudio: 2,208,320
Total number of sessions using a segment in GA: 748,828
Total number of sessions using the same GA segment in Datastudio: 753,269 (Okish, sampling)
Total number of sessions using a filter in Datastudio: 667,674
The GA filter and the Datastudio filter are made the same way:
- GA segment: Market exactly matches XXX
- Datastudio Filter: Include Market Equal to (=) XXX
We get the same kind discrepancy whatever period of time is chosen, and with other custom dimensions
Thanks for you help!
