We provide a lot of data for download on our website. The web page is just a simple HTML table with download links for data in zip files:

This works great for most of our data sets because one download covers then entire province. But some of our data, such as our lidar data, must be packaged in smaller data sets that only cover a small portion of the province. To help our users select the data that they need we publish an ArcGIS Online web app with an index grid. When the user clicks on a grid cell a pop-up window provides a download link for the data:

The drawback to this method is that it bypasses the Google Analytics tracking code that we have embedded in our website. This means we do not get any download stats for our lidar data like we do for our other data sets:

Does anybody have an idea how I can implement tracking for our lidar data downloads?
Thanks,
Bernie.
