Real Campaign Checker

Catch campaign-link UTM mistakes before launch. Local-first LinkCheck.

real Campaign Checker scans visible links on the page you choose and flags missing, empty, duplicate, or inconsistent UTM parameters. Open the side panel, press Scan, review the health score and issues, copy a corrected URL, or export CSV. Your rules stay on this device. Links on the page are never rewritten. This extension has one purpose: catch campaign-link mistakes before launch. It does not track you, call analytics APIs, or change page content.
