I need a report on which pages in a certain Wordpress category have the most page views within a given time period. Any tips?
Is the Wordpress category available anywhere for you to track? Like in URL/data layer/on the site? If yes, then you could just have a custom dimension for the category and use it in the reports later.
Here is more info about custom dimensions in Piwik PRO: Create a custom dimension | Piwik PRO help center.
