Microsoft Invest - Audio creatives
You can host audio creatives with Microsoft Advertising or traffic them through third-party ad servers, which may be created for traditional radio, streaming radio (TuneIn), music streaming (Spotify), and podcasts.
Audio creatives can provide:
Higher conversion rates: Linear audio creatives can't easily be skipped, so audio creatives typically lead to higher conversion rates. Additionally, with audio creatives, you can broaden your targeted audience by including mobile devices as many users use their smart phones and tablets to stream music and podcasts.
1:1 intentional content: Audio creatives can easily be personalized for each targeted audience, instilling emotion and memorability through the use of voice.
