É necessário que o vídeo tenha som?

Yes, sound is essential for Mercado Ads Clips. The platform considers audio (music or voiceover) a crucial component for an immersive experience and technical quality. Videos without sound are perceived as incomplete or low quality, negatively impacting user retention and content delivery by the algorithm. Sellers must include appropriate background music or a clear voiceover to complement the visual appeal, convey professionalism, and maintain consumer attention throughout the video. While a voiceover alone is acceptable, music provides an additional layer of engagement. Therefore, the correct answer is that sound is required and can be either music or a voiceover.
