A campaign URL you can check
https://example.com/offer?utm_source=meta&utm_medium=paid_social&utm_campaign=autumn_launchIn this example, source is meta, medium is paid_social and campaign is autumn_launch. If a redirect lands on https://example.com/offer without those parameters, the route has lost that campaign context. Read the tags here first, then use the full scan to compare the submitted and final URLs. Missing UTMs alone do not prove that every analytics or ad platform will lose attribution.
