Mizu Link Lab – UTM Builder & Checker

Create campaign tracking URLs, check UTM parameters, and copy links. Works locally, with no account or site access.

Create a campaign tracking URL in seconds: • Enter a destination website URL. • Choose a marketing channel preset or enter your own source and medium. • Add campaign name, and optional term or content tags. • Generate a link that preserves other URL parameters and fragments. • Copy your tracking URL with one click. Check campaign URLs before publishing: • See existing UTM source, medium, campaign, term, and content fields. • Spot missing core UTM fields and duplicate UTM parameters. • See possible casing issues and supported ad click identifiers. Privacy-minded by design: • No account or sign-in. • No permissions requested. • No analytics, advertising SDKs, or telemetry. • URLs stay in the extension; the extension makes no network requests. Note: If you use Google Ads with Google Analytics 4, auto-tagging may already provide campaign attribution. Add manual UTM parameters when they fit your measurement setup.
