What Are UTM Parameters? (And Their Limit on Telegram)

What are UTM parameters? UTMs (Urchin Tracking Module parameters) are tags you add to the end of a URL (utm_source, utm_medium, utm_campaign, utm_content, utm_term) to identify where a click came from: which platform, which campaign, which creative. Any analytics tool installed on the page that receives the click reads these parameters and groups visits by source, with no paid tool required.

A tagged ad link looks like this (illustrative values):

https://yourpage.com/?utm_source=facebook&utm_medium=paid&utm_campaign=vip-launch&utm_content=video-01

The campaign and the creative travel with that visit, as long as the person stays on the web.

The limit of UTMs on Telegram

A UTM only exists while there’s a URL and a browser reading it. The moment someone leaves the bridge page and opens the Telegram app, the parameter stops traveling: Telegram doesn’t read utm_*. That’s why a UTM on its own identifies the click, not the actual channel entry.

Where UTMs still count: the source of each lead

That doesn’t make UTMs useless in a Telegram funnel. They’re still how you tell which campaign each person came from. In Track4you, the entry link (the one on the page’s button) is one per funnel, not one per campaign: what separates campaigns is the UTMs in the ad’s link (utm_source, utm_medium, utm_campaign, utm_content). The script on the page records that source with the visit and the click, and each channel entry shows up in the Metrics screen (“Métricas”), lead by lead, with the UTMs of the campaign that brought it. An ad without UTMs produces leads with empty UTM columns.

UTMs identify the campaign, not the individual click. For conversions that happen on another platform, like a deposit at a sportsbook, that job falls to the click ID.

See the Telegram UTM tracking guide for how to structure your naming in practice, and why UTMs alone can’t track Telegram to understand that structural limit in depth and what closes the loop.
