Joe 正在制定创意策略。他的目的是抓住观众的注意力，并讲述一个故事。对于图像和文案，他应该考虑哪两个因素？

Joe's goal is to capture attention and tell a story, making consistency and coherence crucial. "Ad creatives should be consistent and easily recognizable" ensures that the audience can quickly identify the brand and follow the narrative across different touchpoints. This builds brand recall and trust. "Images and copy should have a coherent feel" means the visual and textual elements work together seamlessly to convey a unified message, enhancing the story's impact and preventing audience confusion. The option "More photos than illustrations should be used" is not universally true; the choice between photos and illustrations depends on the brand's style and message. "Copy should be more than 150 characters" is also not a universal rule; effective copy can be concise or detailed, depending on the platform and objective.
