What is a UTM link?

UTM parameters are tags you add to a URL so analytics tools can tell where your traffic comes from. The five standard parameters are source, medium, campaign, term and content. Keep your naming consistent (lowercase, no spaces) so your reports stay clean. Want tracking without exposing long UTM strings? An OnLynk smart link tracks clicks, countries and devices behind a short, branded URL.

Which UTM parameters are required?
Source, medium and campaign name are the most important. Term and content are optional.
Should I use spaces in UTM values?
Avoid them. Use lowercase letters and underscores or hyphens so your analytics groups them correctly.
Does this tool store my links?
No. Everything is built in your browser, nothing is sent to a server.
