If you’re struggling to move people to buy, analyze your ads to ensure you’re optimizing for the right mood. One study suggests that even browsing potential purchases (and not buying) alleviates feelings of sadness. To apply this to marketing, ensure your imagery mirrors the intended mood – as Calm does with peaceful, relaxing imagery in its meditation app ads. Make the ordinary feel extraordinary, which IKEA does with a clever crib ad. Work backward from the emotion you want people to feel to determine what mood your ads should invoke.
