I have some questions with the csv data aggregate format from datawarehouse:
1. when I select "Mobile Device Type, Operation System Type, Browser Type" and "Page Views", the output format is like this:
We can see that there list what we want.
2. However, when I add "Pages" as another break down, I get format like follows:
We can see that there is a row with no content, does that mean "the page view number for device=gaming console, os=null, browser=google, pages=null is 0"?
If Page Views = 0, then it is from s.tl() call i.e. Download link, external link, custom link etc.
Arun is spot on here. You can validate this by adding another metric besides page views, such as visits. Custom link calls do not collect pagename, nor do they count towards page views. The data still technically exists though, and it needs a row to display that data.
thanks for your answer, but I'm still wondering what's the true meaning for my question.
