Do static ads still work?

Emphatically. Static regularly wins on cost efficiency because production is cheap and testing is fast, and this collection’s days-running data shows image ads sustaining months-long runs across every vertical.

What makes a good static ad?

One-second legibility. A single claim in big type, a product with annotated benefits, or a piece of proof (a review, a comparison) that needs no explanation. If the frame requires study, the scroll has already happened.

When should I use static instead of video?

When the claim is simple, when testing many angles cheaply, and when retargeting warm audiences who already know the product. The strongest accounts in the library run both and let cost per result arbitrate.
