Overview
The Hosted Pixel can automatically detect and capture the last touch marketing channel that brought a user to your site. This value is stored for the user’s current session and automatically passed along in the lastTouchChannel parameter during conversion events — helping you track which marketing channel drove the conversion.
🔧 What This Feature Does
When someone visits your site, the tvScientific pixel:
Looks at the URL (for example:
https://example.com/?utm_source=adwords)Finds the parameter you’ve chosen to track (like
utm_source)Stores the value (“adwords”) for the session
Sends that value with every conversion event (as
lastTouchChannel=adwords)
If the same user later visits your site through a different channel (for example: utm_source=facebook), the stored value updates to the new one.
