Great question!
Here’s a solid, go-to troubleshooting checklist to help uncover what’s blocking delivery:
1. Check Campaign Start Date & Time
2. Review Budget & Bidding Strategy
Confirm you have enough daily budget to enter auctions (e.g., Meta and Google may deprioritize very low bids).
If using manual bidding or Cost Cap, the cap may be too low for the auction.
3. Audience Size Too Narrow?
4. Placement or Platform Restrictions
If you selected only a few placements, those may not have enough inventory.
Switch to auto placements temporarily to test.
5. Creative or Ad Fatigue
Even if ads are approved, poor performance history (from reused creatives) can limit delivery.
Try fresh creatives or new copy variations.
6. Conflicting Settings
Look for conflicting campaign vs. ad set vs. ad-level settings (like device targeting, OS, languages).
Make sure all settings align properly.
7. Check Account Health
Make sure there are no billing holds, payment issues, or policy warnings.
Even small billing errors can pause delivery silently.
Tip:
Start with budget, bid, and audience size. If those look good, test with broader placements and check for hidden platform issues. Often, it’s something small—but easy to miss.
