Free UTM Link Builder Online — Campaign URL Tagger
UTM parameters are little tags you add to a link (?utm_source=…&utm_medium=…) so your analytics can tell where a visitor came from — which newsletter, ad, or post. Without them, traffic just shows up as “direct” or “referral” and you can't tell what's working. This builder assembles a correctly-tagged URL from your source, medium, and campaign so every click is attributable.
