Brand Voice Social Media Style Guide AI Prompt
Keeping social posts consistent gets hard once more than one person writes them. You end up with mixed tones, shifting terminology, and captions that don’t sound like your brand.
A strong prompt fixes that by spelling out your audience, voice rules, do’s and don’ts, and real examples your team can copy. AskSmarter.ai helps you build that prompt through a few focused questions, so you don’t forget the details that drive consistent output.
In this example, you’ll learn how to:
- Define voice traits that writers can apply
- Lock in vocabulary, banned phrases, and formatting rules
- Generate ready-to-use post examples for common scenarios
You’ll save time, reduce edits, and ship on-brand content every week.
The transformation
Before — Vague prompt
Make a brand voice guide for our social media and give some examples.
After — Optimized prompt
You’re a senior brand copywriter. Build a social media brand voice style guide for [Company], a [industry] brand.
- Audience: [primary persona] on LinkedIn + Instagram.
- Voice traits: choose 4 traits with a 1-sentence definition each.
- Rules: list 10 do’s and 10 don’ts (active voice only, short sentences).
- Language: include preferred terms, banned phrases, and a CTA library (8 options).
- Examples: write 6 on-brand posts (3 LinkedIn, 3 Instagram), each 80–120 words, for: product update, customer win, hiring, event promo, tip, and objection handling.
Use a professional, approachable tone. Keep everything skimmable with headings and bullets.
Why this works
The weak prompt asks for a “guide” but leaves the AI guessing. That leads to generic rules and examples that won’t match your brand.
The improved prompt works because it adds clarity, context, and structure:
- Clear role: A “senior brand copywriter” frames expert-level decisions.
- Specific channels: LinkedIn and Instagram need different pacing and formatting.
- Defined audience: Personas shape vocabulary, proof points, and CTAs.
- Concrete deliverables: You get traits, do’s/don’ts, a CTA library, and examples.
- Tight constraints: Word counts, active voice, and skimmable formatting reduce rewrites.
AskSmarter.ai gets you to this level by asking the missing questions upfront. It pulls details like channels, persona, and forbidden phrases. That context turns a vague request into a guide your whole team can follow.
