UTM Builder & Checker

Build clean UTM links for the page you are on, save presets, and check UTMs and click IDs on any page.

Build clean, consistent UTM links in seconds, and catch tagging mistakes before they mess up your GA4 reports. BUILD • The current page's URL is filled in for you (old UTMs and click IDs removed) • Starter presets for Meta Ads, Google Ads, TikTok Ads, LinkedIn and email, plus your own saved presets per client • Naming rules: force lowercase and replace spaces with _ or - • All GA4 fields: utm_id, source_platform, creative_format, marketing_tactic • One click to copy, and a history of the links you made CHECK • See the UTMs and click IDs (gclid, fbclid, msclkid, ttclid…) of any URL • Warnings for duplicates, missing source/medium/campaign, uppercase values and mediums GA4 will put in "Unassigned" SCAN A PAGE • Audit every link on a landing page or email preview • Finds inconsistent spellings ("Facebook" vs "facebook") that split your GA4 reports • Flags UTMs on internal links, which overwrite the real traffic source PRIVATE Everything runs in your browser. No data is collected or sent anywhere. Built by Jobair Mahmud, GA4 and conversion tracking specialist. More free tools at jobairmahmud.com/tools
