Is there an easy way to filter between posts and pages in Google Analytics?
Page is listed as a Primary Dimension when I drill down to Content but I'm not sure if that includes posts as well.
It's not tracked by default.
Yoast's WordPress SEO plugin allows you to track post types (and categories and authors...) as a custom variable.
get_post_type()
.
Page in Google Analytics is simply the webpage. You can do a search for your category slug to drill down posts and post categories. That's how I do it.
