HELP: How to set goals properly

Hi there,

I’m looking for help regarding how to properly define goals in Piwik.

I’d like to track the following file:
http://www.brainproducts.com/filedownload.php?path=products/brochures_material/actiCAP.pdf

The code looks as follows:

actiCAP Brochure - V005
Type: pdf   Size: 728.0 KB

I’ve already tried various things (in the goals section; following the description here: Track Goals and Measure Conversions - Analytics Platform - Matomo) in order to have that file (and others that are similar) tracked by Piwik but nothing worked.

Any suggestions and/or a link to detailed instructions on how to set goals in such cases would be extremely helpful!

Thanks already for your support,
Stefanie
