Simple Tracking for Video Views
The simplest and no-code approach to this seems to be to use Superlinks.
Create the Superlink, and embed it in your email or page. Set a tag to be added on click.
Use that Tag Added Benchmark in the funnel builder to catch the event, then the Add Note action with something like
{date.Y-m-d|now};Video Watched;ID=12345 – with the date replacement code optional.
The note will be in the wp_prefix_gh_notes table, and you can search on the note field for “Video Watched”, etc., and do as you wish with the timestamp and date_created.
