Google Analytics Reports: how to remove pageviews for Top Pages and add published date
You're looking a one difficult task &amp; one simple one. Starting with the simple one (reverse order):


The Top Pages area is a block that's installed with the module. The Google Analytics Reports Summary (Google Analytics): Top Pages view can be configured in the Views UI (/admin/structure/views/view/google_analytics_reports_summary/edit/attachment_top_pages). To remove the views count you can click the Page Tracking: Pageviews field and use the Remove button or Excluded from display checkbox to get rid of it.
Adding the publish data is a bit harder because what the underlying View is querying. The view is querying data tables from your Google Analytics account. As such, there is no Drupal node data to display from the query. Normally, the Views way to solve this would be to add a relationship with the node table then reference the publish date. However, the module doesn't provide a relationship handler to node content so you're looking a couple things here:


Select a Google Analytics field that can be joined on the node table. Page Tracking: Page is a close candidate here as it contains a unique path used for the node link. Nid would be better, but that data isn't sent to Google Analytics by default (you'd have to configure a GA custom variable).
Once you have a selected joined field. You'd have to build your custom relationship handler on which you can join to the node table to retrieve the publish date.
