Google Analytics medium : "banner" and "Banner" (not in the same channel group)

Question

I'm exploring Google Analytics features and I've noticed something surprising.

Unless I'm mistaken, the banner medium is associated with the default system channel group Display, although the Banner medium is associated with the ground (Other).

According to the Default channel definitions, the Display group use the regex ^(display|cpm|banner)$

The filters on regex seems to be case-insensitive(as explained here). As a result, when I try to get the data for the Google Analytics API when the filter ga:medium=~^(display|cpm|banner)$,ga:adDistributionNetwork==Content;ga:adFormat!=Text, I get results for both "banner" and "Banner" medium.

However, when I check on the Google Analytics website, the banner medium is in the Display group, and the Banner is in the (Other) group.

Could you please confirm me this point (and explain if possible :)) ?

Thanks a lot !

Answer 1

Banner is being placed under (Other) because it is capitalized. What you can do is create a filter that will convert any campaign parameters to lowerCase.

To do this:

1. Create a new filter > select "Custom Filter"
2. Select the Lowercase filter
3. And from the dropdown, select Campaign Medium

This will convert all of your campaign mediums to lowercase, and will place them in the correct channel grouping.
