Tracking Download Events
Wide Angle Analytics supports two standard download actions. One triggered by file extension and one by a named HTML tag.
Tracking download of files with known extensions
The most straightforward Download Action is an action when a visitor or a user downloads a file with a known extension. Currently, Wide Angle Analytics supports the following extensions: 7z, zip, bz2, gz, tar, tgz, tbz, tbz2, z, gzip, rar, apk, deb, rpm, bin, exe, msi, dmg, jar, gif, jpeg, jpg, png, webp, ttf, otf, woff2, acc, ogg, flac, mp3, mp4, mpeg, csv, xls, xlsx, doc, docx, ppt, pptx, pdf, txt.
This mode is enabled by setting Enabled - for known file types in the site's Download Tracking option.

Tracking marked files
Perhaps you don't really want to track all the files. Maybe you host a sleuth of PDFs but need to track only a few. This can help keeping your events budget in check.
You can achieve this with so-called marked download events. When Download Tracking is configured to Enabled - marked links, then only links with data-waa-name
attribute will generate an event.

An example HTML with marked download link:
<html>
<body>
<a href="/foo/case-study.pdf" data-waa-name="case-study-may-2022">
Tracked PDF link
</a>
<a href="/foo/financial reports.pdf">
Not tracked PDF link
</a>
</body>
</html>
In closing
You can track downloads on either known files or explicitly marked links. Once you enable tracking events, you can continue visualizing events in your dashboard.
