Tip 1: Carefully select the persona

Tip 1: Carefully select the persona

Many times when writing system prompts for conversational tasks, it’s common to default to roles like “You are a content marketing leader” or “You are a content marketing expert.” Instead, focus on the persona best positioned to speak to your ideal reader.

Why persona matters

• For technical audiences, a Software engineering leader persona resonates more than a marketing expert.
• For marketing or non-technical audiences, a Content marketing leader may be the better fit.

Example: Crafting a LinkedIn post about Ramp’s AI Agents
A Workflow is set up to draft a simple LinkedIn announcement. Context from Ramp’s page is loaded, and the system prompt defines the persona.

• Persona: Content marketing leader at Ramp
  • Output traits:
    • Phrases like “Here’s what makes this a game changer”
    • Patterns such as “This isn’t X, it’s about Y”
    • Rhetorical questions: “Ready to see your ______ in action?”
• Persona: Software engineering leader at Ramp
  • Output traits:
    • More refined tone: “We’ve built this product…”
    • Avoids language like “game changer”
    • Reduced AI-generated speech patterns
    • May still include rhetorical questions, but reads more authentic for feature announcements

Key takeaway
Again, the key is to choose the persona that is best positioned to write to the audience you want to reach.
