Way back in the early days of the site there was a discussion about whether questions about Google Analytics were on- or off-topic.
The accepted answer (and, for a time) the answer with the highest score was that they were on-topic.
The votes have since reversed, but since there's so few of them I don't think that can really be a measure of community consensus.
After four+ years though, it seems to me pretty clear that questions about Google Analytics are a poor fit here. Sure, the administrative functions of Google Analytics are a web app, but by-and-large the questions are about how to manipulate and analyze the data, not how to use the app.
Have a look at some of them: https://webapps.stackexchange.com/questions/tagged/google-analytics
Meanwhile, over at Pro Webmasters, they also have questions about Google Analytics that are the same sort of questions, but they get more and better answers: https://webmasters.stackexchange.com/questions/tagged/google-analytics
(There's also at least 10 times more questions than here.)
I think we should change policy and make Google Analytics off-topic by default.
