What is Angle Saturation?

In plain English: The market has seen this framing a thousand times. The product might be fine. The story is worn out.

When a specific creative angle (pain point framing, persona, product positioning) has been run by so many advertisers that the target audience is desensitized to it. The audience has seen the same hook, the same problem setup, and the same type of solution enough times that it no longer generates response.

Why it matters: Angle saturation is the most common reason a previously profitable product stops converting, not algorithm changes, not increased competition on CPMs. The product may still work; the angle is exhausted.

Attributing ROAS decline to "the algorithm" without checking the Meta Ad Library for competitor saturation. Search your product category. If 100+ advertisers are running the same angle, you need a novel one.
