Use the Brand Voice settings in the Marketing Hub to make generated content sound more like your brand.
Tone, such as friendly, confident, or professional
Level of seriousness, from formal to conversational
Balance of facts and emotion, such as data-driven proof points versus storytelling
Words and phrases you prefer or want to avoid

Be specific. Describing your brand as "warm and encouraging, like a mentor" works better than just "friendly."
Include examples of copy your team likes, such as your website or past posts.
Make sure Brand Theme includes your logos, colors, and style guide.
You do not need to change your whole content approach to fix a single post. You can refine an individual generated post on its own, such as adjusting the tone or adding a detail, without affecting the rest.
As your brand messaging evolves, update Brand Voice so future content stays aligned.
