🔍 Common Publication Error Causes
Google Ads campaign publication fails when required fields are missing, policies are violated, or API settings are outdated. The most frequent causes include invalid start date format, policy violations in ad copy, incorrect targeting settings, and OAuth account mismatches.
⚙️ Verify Campaign Settings Before Publishing
- Navigate to Left sidebar → Smart Ads → Campaign Hub.
- Select the campaign showing the error.
- Check that all required fields are complete: campaign name, budget, bidding strategy, target locations, and language.
- Ensure the start date uses the correct format. Recent API updates require start_date_time instead of start_date. If you see a date-only field, update it to include time (YYYY-MM-DDTHH:MM:SS).
- Confirm ad groups have at least one responsive search ad with headlines and descriptions that meet character limits.
- Verify keywords are added to each ad group and match the targeted language.
🛡️ Check Google Ads Policy Compliance
- Review ad copy for prohibited content: misleading claims, trademark misuse, adult content, or restricted products.
- Ensure landing pages comply with Google's destination requirements — functional, relevant, and transparent.
- Confirm ad extensions (sitelinks, callouts, structured snippets) follow policy guidelines.
- Use the Campaign Audit tool at Left sidebar → Smart Ads → Campaign Audit to auto-detect policy issues before publishing.
-
- Go to Left sidebar → Smart Ads → Campaign Hub.
- Click Refresh data to force a fresh sync with Google Ads.
- If the issue persists, disconnect and reconnect your Google Ads account through the integration settings.
- Verify the correct manager account (MCC) and client account are selected during reconnection.
-
- In Campaign Hub, click Create new campaign.
- Set a daily budget of $5, one target location, one language, and a single ad group with one responsive search ad.
- Use generic, policy-safe ad copy (e.g., "Quality Services | Free Consultation").
- Publish and monitor for errors.
