Short answer
Ad titles: 16–24 characters recommended, 50 maximum. Ad copy: 32–48 characters recommended, 100 maximum. Images: square PNG or JPG, no larger than 1200 × 1200 pixels, publicly accessible. Landing pages must be reachable and must not block OAI-AdsBot.

- Not square
- Larger than 1200 × 1200
- Wrong format
- URL opens a preview or sign-in page instead of the image itself
