First, double-check your campaign settings in Google Ads. Make sure your campaign type includes YouTube placements and that your ads are targeting the right audience, devices, or locations. Next, confirm your budget and bidding strategy. If your bid is too low or your budget is exhausted, your ads might not appear. Also, ensure your ad meets YouTube’s policies and ad quality standards, as disapproved ads won’t run. Review your placements to ensure your ad is eligible for the content and channels you’ve selected. If you’re targeting specific YouTube videos or categories, there might be limited inventory. Finally, use the Ad Preview and Diagnosis tool in Google Ads to check for any underlying issues. If all else fails, contact Google Ads support—they’re super helpful
