On several pages of my portal I have different functionalities to sort and filter the content. For each selected filter a parameter is added to the url. I want to see how many times a filter is called. So basically I need to track url parameters. How can I do that with piwik?
I too would be interested in this but could not figure out how to create a custom report based on specific URL parameter(s).
If I understand correctly this thread PIWIK Log ANalysis, Matthieu seems to recommend using custom variables for URL parameters
We would now recommend custom Dimensions, not custom variables
See: What is the difference between Custom Dimensions and Custom Variables? - Analytics Platform - Piwik
