GTM Conversion Tags Not in Ads
One or more Google Ads conversion tags in your GTM container do not match any conversion action in your Google Ads conversion settings. The tags fire on real user behavior, the hits go out to Google, but they land against a Conversion ID and label that Google Ads no longer has on file. The tag thinks it is working. Google Ads silently discards every hit.
Why It Matters
Each Google Ads conversion tag sends a `send_to` value made of an AW Conversion ID and a conversion label (`AW-123456789/abcDEF`). Google Ads matches that pair against the configured conversion actions in the account. If no action matches, the hit is dropped. There is no warning, no error log surfaced to the advertiser, and no row added to the Performance report. The hit just disappears. The usual root causes are predictable. The Google Ads action was deleted or archived during a cleanup pass while the GTM tag was left in place. The account migration moved conversion actions to a new Google Ads account and the GTM tag is still pointed at the old account's Conversion ID. The label was regenerated (some workflows force a new label on edit) and the tag is still sending the previous label. The critical severity reflects how silent the failure is. The GTM container looks healthy. The tag fires in Preview mode. Tag Assistant shows a green hit. Only by comparing GTM tags against the live Google Ads conversion settings can you see that the hits are landing nowhere.
How To Fix It
- Open the AdLint details and list each orphaned GTM tag with its name and the implied conversion action.
- For each, open the tag in GTM and read the Conversion ID and label. Then open Tools and Settings > Measurement > Conversions in Google Ads and confirm whether any action carries that exact ID and label.
- If the matching action exists under a different name, update the GTM tag's name to match. The hit will start landing again immediately.
- If no matching action exists, either create one (if the tag should be live) or delete the GTM tag (if the action is genuinely obsolete).
- Verify in GTM Preview that the hit completes, then check the Google Ads Performance report after 24 to 48 hours for newly-recorded volume.
Example
GTM tag: "AW - Lead Submit"
send_to: AW-987654321/oldLabel
Google Ads: no action matches that ID and label.
Likely cause: action was archived during a Q2 cleanup. Tag was never updated.This GTM container has Google Ads conversion tags whose Conversion ID and label do not match any action in the connected Google Ads conversion settings. Per Google's conversion-tracking documentation, the `send_to` value on the conversion request must match a live conversion action; hits with no matching action are silently discarded with no error surfaced to the advertiser, while the GTM tag continues to appear healthy in Preview and Tag Assistant. The typical causes are deleted or archived conversion actions, account migrations that left tags pointing at the old account, and regenerated labels. Fix: identify the implied action for each orphaned tag, repoint or rename to match a live action, or delete tags whose actions are genuinely obsolete, then verify newly-recorded volume in the Performance report.
