Tracking Ad Revenue

Hi there,
I would like to track ad revenue inside piwik. I suppose I could use the ecommerce-tracking for this, but there are some challenges:

  • The value is very low, usually below 1 cent
  • There would be at least one on every page view (I would use the products for the specific ad locations)

Can piwik deal with values below 1 cent? If not I could probably thousandfold them all.
Would it cause issues with so many “purchases”, since it could be 5 cart items for every page view.
