Start here
Give the writer real examples, a few concrete voice rules, verified facts, and one action for the reader. Review the draft aloud, remove invented details, and keep the wording you would actually use with a customer.
Start with language you already use
Choose three captions or customer-facing messages that sound like your business. Remove private information. Mark the phrases you would happily say again, and explain why they fit: direct, playful, quietly confident, or careful with technical detail.
Also keep one example that feels wrong. Explain the mismatch, such as too many emojis, vague praise, or a pushy booking request. Concrete examples give a writer more direction than simply asking for an authentic tone.
Turn the examples into a short working brief
Separate voice from facts. Voice can stay consistent across a month of posts; hours, prices, stock, and appointment availability must be checked for each post. The template below works with a human writer or a caption generator.
Example to adapt
Business: [what you do and who you help] Voice: [three plain-language qualities] Sentence style: [short / conversational / explanatory] Words we use: [specific examples] Words we avoid: [specific examples] Emoji preference: [none / occasional / describe your usual pattern] Writing samples: [three short approved examples] This post's verified facts: [service, event, product details] Reader's next step: [one action] Do not invent testimonials, prices, scarcity, or performance claims.
Compare two drafts for the same post
Consider a fictional neighborhood salon announcing consultations for layered cuts. Its voice is calm, practical, and friendly. The business has not supplied appointment counts, prices, or client quotes.
A draft such as ‘Transform your look with our revolutionary signature cut! Limited slots, book NOW!’ adds unsupported scarcity and uses language that does not fit the brief. Revise the facts and tone together.
Example to adapt
Revised example: Thinking about layers, but want to keep your length? Bring a reference photo to a consultation. We will talk through the shape you like and how you usually style your hair. Check the booking link in our profile for consultation options.
Review facts first, voice second
Reading aloud helps catch wording you would never use in person. Keep the useful detail and cut generic introductions. A draft does not need to sound clever to answer a real customer question.
- Check every name, service, date, price, quote, and availability claim.
- Match the caption to the actual photo or video, including styling context.
- Read it aloud and replace words your team would not say.
- Keep one clear next step and verify any referenced link.
- Remove unnecessary hashtags; retain only relevant ones you have reviewed.
