About UTM parameters
UTM parameters are tags added to a URL — utm_source, utm_medium, utm_campaign and optional utm_term/utm_content — that let Google Analytics and other tools attribute a visit to a specific campaign, channel and creative.
Consistency is everything: Facebook and facebook become two sources, so agree a naming convention and stick to it. This builder encodes values correctly and preserves any existing query string, giving you a clean, trackable link to copy.

What are UTM parameters?
Tags added to a URL (utm_source, utm_medium, utm_campaign, and optional utm_term/utm_content) that let analytics attribute a visit to a campaign, channel and creative.
Why does consistency matter?
Analytics is case-sensitive — Facebook and facebook become two sources — so agree a naming convention and stick to it.
Does it preserve existing parameters?
Yes. It keeps any query string already on the URL and adds the UTM tags.
Does it run in my browser?
Yes, entirely client-side.
