UTM Campaign URL Builder

Tag any link so GA4 / analytics can tell you where visitors came from. Fill in the fields — the tracked URL builds live. Runs in your browser; nothing is stored.

The five UTM parameters

ParameterRequired?Example
utm_sourceYeshackernews, reddit, bluesky, newsletter
utm_mediumYessocial, referral, email, cpc
utm_campaignYeslaunch_2026, spring_sale
utm_termOptionalpaid-search keyword
utm_contentOptionalhero_cta vs footer_cta (A/B)

Tip: keep values lowercase and consistent — GA4 treats Reddit and reddit as two different sources, which fragments your reports.

UTM parameters are the Google Analytics standard for campaign tracking. This tool builds the URL locally; no link or data leaves your browser.
