Creative considerations

1. Understand your audience

Research shows a personalized message is more engaging across mediums.

2. Consider the context

  • Understand platform specs and which ones support companions.
  • Consider how people listen to content on different platforms.

3. Keep it brief and memorable

  • Shorter clips have higher recall.
  • Include a clear call to action.
  • Repeat the brand name 2–3 times.

4. Be thoughtful with sound

  • Balance the mixing between voiceover, music, and other sound effects.
  • Use storytelling techniques for engagement and recall.

Audio best practices

1. Use a consistent tone and tempo

  • For 30 second ads, aim for 55-75 words
  • For 15 second ads, aim for 40 words

2. Be conversational

A friendly tone transitions listeners between entertainment content and ads.

3. Include a call to action

Give listeners a chance to engage. A direct call to action drives higher clickthrough rates.

4. Tell a story

Transport the listener through the use of subtle effects and environmental sounds that create imagery in the mind.

5. Create multiple versions

Develop a variety of audio ads tailored to unique audience preferences.

Dos & Don'ts

Do

Don't

Use simple background music that sets an emotional tone and doesn’t compete with the voiceover. Incorporate jarring sounds effects (alarms, air horns) or cheesy jingles which could annoy listeners.
Use a balanced mix of sound elements. Use multiple voices, which can confuse listeners.
Incorporate music only if it complements the message. Be intrusive, consider audio goes directly into a listener’s ears.
Consider using music similar to your audience’s preferences. Try to explain every benefit your product or service provides — stick to what’s most relevant for the audience.
Incorporate audio elements and storytelling techniques that transport the listener through sound.  

Companion best practices

Use a companion to reinforce your message

  • A visual companion is the strongest connection back to the brand.
  • Use the brand logo, repeat the call to action, and other elements that reference the audio ad.
