Responsive search text ads have 15 headlines and 4 descriptions.
I cannot see these fields in the dimensions list when I try to split them out.
Hi, we have just added new dimensions to the Responsive Search Ads group.
I do not know if you are meaning for these dimensions. If not, do you mean for headlines 1, 2... or the multi-asset ones?
While we are at it, is there capacity to clean up the naming of the fields for expanded text ads? I can see description, description line 1 and description line 2, and also expanded text ad description 2, but not expanded text ads description 1. I assume these are similar, but just naming them more clearly will help me.
Expanded text Ad Description 1 does not exist in Adwords API. The dimension you are looking for is Description.
