I'm currently using google Analytics for a broad overview, but I'm unable to drill it down to different channels. Also, it's limited because it only allows to set up pages for goals, not actions.
What I basically want is a tool that enables me to see where my users are coming from and how they convert (signups, trial, paid package).
Ultimately, I just want to get an idea which (paid) channels are worth it.
What are you using, any recommendations?
