How to Resolve Facebook Ads Error Code 1815762 – Your Ad Isn’t Delivering
This error is a bit vague but often occurs when Facebook detects an issue with your ad content. It could be related to the ad’s text, image, or targeting. Facebook Ads error code 1815762 shows the error message, “Invalid Optimization Sub Event for Objective: The chosen optimization sub event is not supported by this objective (#1815762)”
Here’s how to tackle it:
- Review Your Ad Content – Check if your ad complies with Facebook’s ad policies. Ensure there are no prohibited content types like misleading claims, excessive text on images, or restricted products.
- Adjust Your Targeting – It’s possible that your targeting is too narrow, causing your ad to reach too few people. Broaden your audience if needed.
- Check Your Bid – Your bid may be too low, making it difficult for your ad to compete in the auction. Try increasing your bid slightly.
- Ad Account Quality – If your ad account has a history of policy violations, it could be causing this error. Make sure your account follows Facebook’s advertising guidelines.
