Each creative counted once, however many ads it runs as. Every platform publishes a different public sign an ad is working, so each row shows its own.
Every ad in our libraries is scored out of 10 by an AI model built to judge creative, up to 5 for how well it would land with a senior B2B buyer and up to 5 for craft. 7 of Plain's ads made the top-rated tier.
