Meta's adult nudity and sexual activity policy rejects ads focused on individual body parts such as the groin, buttocks or breasts, and ads showing sexually suggestive poses or revealing clothing. For swimwear, lingerie and fitted pieces, shoot full-length or product-only with neutral poses. Google classes partial nudity, such as most of the buttocks exposed, as moderately restricted, so those ads only show where the viewer's age, local law and SafeSearch settings allow.
Both platforms ban counterfeits: Meta rejects ads for knockoffs, replicas or anything likely to confuse people about who makes a product, and Google suspends accounts for counterfeit goods on detection, without prior warning. Never call a piece a replica or knock-off of a named brand. In Google Shopping, your feed's price and currency must match your landing page and checkout, so update it when a sale ends.
