I have a website where there are differing “silos” of information. In Google Analytics for our old website, we were able to track the statistics for each of these “silos” by a keyword. In the new website, I think the only way to compartmentalize them is by their breadcrumb trail in the site map. I’d like to see a way to get statistics by all child pages of a specific parent page in our site map.
I’m having a very similar, if not the same challenge as you.
Are you able to extract the breadcrumb values as Custom Dimensions? (Child being the last breadcrumb value and Parent being the previous).
That is assuming the breadcrumb is hierarchical and not dynamic to the user journey.
