UTM parameters are small tags you add to the end of a link (source, medium, campaign and more), so analytics tools can record which source, channel and campaign a visitor came from.

The foundation for attributing results
Without UTM tagging, your analytics often don't know where a visitor came from, and the traffic drowns in “direct” or “unknown.” UTM parameters solve that by tagging each link with source (like newsletter), medium (like email) and campaign, so you can see exactly which effort drove visits and sales.
The value depends on discipline: a consistent naming convention across channels is the difference between usable data and a messy tangle. Set up right, UTMs are the foundation for honest channel reporting, but remember they tell you about source, not about incrementality.
Frequently asked questions
What are UTM parameters used for?
To track which source, channel and campaign a visitor came from, so traffic and sales can be attributed to the right effort in your analytics. Without them, a lot of traffic ends up in 'direct / unknown'.
Do UTM parameters tell you about incrementality?
No. They tell you where the traffic came from, not whether the sale would have happened anyway. For that question you need MER and incrementality tests. UTMs are for source tracking, not for measuring real added effect.
