UTM Checkers and GA4 Channel Tools

These tools check links you already have. Decode one tagged link, audit up to 10,000 URLs against naming rules, or see which Google Analytics 4 default channel a source, medium or link lands in.

Tools in this group

• Google UTM: Which GA4 Channel Will Your Links Land In? — Paste tagged URLs or source / medium / campaign rows and see which Google Analytics 4 default channel each lands in, which rule matched, and why a row is Unassigned.
• UTM Link Checker: Decode and Clean a UTM Link — Paste a tagged link to see every parameter decoded, the problems in it and the GA4 channel it would get, then copy it without UTM or without UTM and click IDs.
• UTM Medium: Check Which GA4 Channel It Lands In — Type a utm_medium, and optionally a source, to see which GA4 default channel it maps to, why, and whether it would end up in Unassigned.
• UTM Tracking Audit and Naming Convention Checker — Paste or open a list of tagged URLs (up to 10,000) and get every UTM mistake, the values that break your naming rules, near-duplicate spellings, GA4 channel counts and a CSV report.
