If YouTube Promote cannot link a Google Ads account, the selected Google profile usually lacks the required account access or the wrong account is already linked. Fix the administrator permissions and linking path before creating a new promotion.
Check the exact status first
In YouTube Studio → Settings → Promotions, inspect the linked Google Ads account and the account selector. Note whether the issue is a missing account or an access error.
Fix it in YouTube Studio Promote
Follow these steps in order. If a setting is locked, stop and check the account role or asset ownership before rebuilding the campaign.
- Confirm the Google profile you are using has Admin access to the intended Google Ads account.
- Ask the account owner to grant the required role if it is missing.
- In YouTube Studio Settings → Promotions, unlink the incorrect account if necessary.
- Link the account where your profile has the correct access.
- Return to the promotion setup and confirm billing is available in the linked account.
Verify before changing the campaign again
Use a fresh status check after saving. Avoid raising the budget, changing the audience, and replacing the creative until the original issue has cleared.
- Confirm the intended Google Ads account appears as linked.
- Check that you can create and edit a promotion.
- Do not unlink a working account without recording its active promotions.
THE TAKEAWAY
Fix the stated error first, then change only one campaign variable at a time so you can see what actually resolved it.
