AI Prompts for Social Media: Draft Posts From a Clear Brief

Good AI prompts for social media give the assistant an audience, a channel, approved facts, a purpose, and a review boundary. Ask for a draft built from that material, then check the claim and the action you want readers to take. Generating more versions helps only when those versions explore a useful difference.

fenbs can retain your reusable prompts, brand rules, and campaign context so a connected assistant does not start from an old explanation. The templates below focus on writing and reviewing individual posts. Our AI prompts library covers other kinds of work.

What should a social media prompt include?

Start with the reader and the one thing the post should help them understand or do. Supply the approved announcement, useful source links, the destination page, and any wording that must remain exact. State which information is still provisional. Without that distinction, a draft can turn a possible release date into a public promise.

Choose a specific channel and format rather than requesting something suitable everywhere. A short text post, an image caption, and a spoken video script need different structures. Give your own current format requirements instead of asking the model to recall platform rules or predict what an algorithm will reward.

• Audience: who will read the post and what they already know.
• Purpose: one intended action or takeaway, with the correct destination.
• Evidence: approved facts, source labels, dates, and claims that remain unapproved.
• Voice: a few clear writing rules and examples you have permission to use.
• Review: what a person must check before publishing, including disclosures and accessibility.

For a hypothetical local design studio, the campaign outline might announce an open house with an approved date, address, and registration link. It should not invent limited availability, customer praise, or an offer. Keep those factual constraints separate from requests for a warmer voice or a shorter introduction.

What prompt turns an approved brief into a channel draft?

Ask the assistant to make missing information visible before it writes. Then require one clear draft and a short explanation of any assumptions. A strict output structure helps you review the result without searching through a long conversation for the source of a claim.

Draft a [format] for [channel] aimed at [audience].
Purpose: [one action or takeaway].
Use only these approved facts: [facts with source labels].
Destination: [verified URL]. Voice rules: [rules]. Length: [your limit].
Keep mandatory wording exact: [wording].
Do not invent statistics, testimonials, urgency, availability, or product features.
Return the draft, unsupported details you omitted, and checks needed before publication.

Check the destination yourself and compare the draft with what the reader finds there. A post can be accurate in isolation while implying something the page does not offer. Also check whether the call to action matches the intended relationship: asking an existing customer for feedback is different from asking a new reader to sign up.

Save the reusable structure in fenbs Skills and prompts, with the inputs it needs and the review it expects. For instructions that should apply before every post, see system prompt examples. Keep campaign-specific dates in current context rather than embedding them permanently in the template.

How do you get meaningful variations instead of synonyms?

Define what each version is testing. You might compare a direct explanation with a practical question, or a user problem with a short demonstration. Keep the facts and destination fixed. Otherwise you could choose a version because it makes a stronger promise rather than because its framing is clearer.

Create three variations of this approved draft: [draft].
A: lead with the reader’s problem.
B: lead with the practical takeaway.
C: lead with a question the supplied facts can answer.
Keep the facts, offer, destination, and required disclosures unchanged.
For each variation, name the difference and the audience assumption behind it.
Avoid invented emotion, unsupported claims, and guesses about platform reach.

Ask a colleague to identify the main point after a quick read. If they describe three different offers, the variations changed too much. If the differences are only punctuation and adjectives, ask for a different opening structure. Choose based on the campaign purpose and your actual evidence about the audience.

A post’s later performance can inform a lesson, but avoid claiming one phrase caused a change when the timing, audience, and distribution also differed. Record what happened and what remains uncertain. That makes the next prompt more useful without turning a weak comparison into a permanent brand rule.

How can you adapt a source without changing its meaning?

Give the assistant the actual source excerpt and define the narrower job: choose a relevant takeaway and express it in the requested format. Require it to preserve qualifications and attribute quotations. An excerpt that says an approach may help in a particular setting should not become a universal recommendation.

Adapt this approved source into [channel and format]: [source with label].
Reader: [audience]. Purpose: [takeaway].
Identify the source’s main claim and qualifications before drafting.
Preserve conditions and uncertainty. Do not create a quote or imply the source endorses our business.
Return one draft, the source passages supporting its claims, and any necessary attribution.

Treat a summary as a new piece of writing that needs checking, even when the source is your own. Compare names, dates, quoted language, and causal claims. If the draft depends on a chart, inspect the chart and its labels; a confident description of a missing image is not evidence.

What should the final review prompt check?

Use a review pass to expose problems, not to certify the post. Ask it to separate factual accuracy, brand voice, missing disclosures, and accessibility. A person still needs to check the final text, media, destination, and placement in the actual publishing interface.

Review this draft against [approved facts and brand rules]: [draft].
List: unsupported claims; changed dates or names; unclear action; tone problems; questions for the approver.
Flag relationships to a brand that may need disclosure. Do not make a legal compliance determination.
For the supplied image, draft a text alternative conveying its relevant information. If the image is unavailable, ask for it rather than guessing.
Return issues and proposed corrections separately. Do not publish.

The FTC’s social media disclosure guidance↗ (opens in a new tab) says material connections to a brand should be clear, with disclosures placed where people will notice them. Do not let a shortening request remove an approved disclosure or bury it among hashtags. Have the responsible person check whether the final presentation makes the relationship understandable.

For informative images, the W3C image tutorial↗ (opens in a new tab) explains that text alternatives should convey the essential information. Review a suggested description against the actual asset and its purpose. Promotional language about an image is often less useful than the information someone needs when they cannot see it.

Keep corrections with the campaign work. A repeated problem such as unsupported availability should become a concrete lesson and, when a person chooses, an approved rule. The same principle applies to project management prompts: the instruction needs current facts and visible follow-up work.

How to do this with fenbs

1. Create a free account, then add a project for one active campaign. It is free for one person, with no credit card.
2. Save the drafting, variation, and review templates in Skills and prompts. Name the required inputs and the person responsible for approval.
3. Record approved brand instructions in Decisions and rules. Keep current campaign facts, source references, and open questions with the project.
4. Connect a supported assistant and ask it to read the context before drafting. Save progress afterward, including what was approved and what still needs checking.

fenbs does not publish posts or replace a social scheduling tool. Keep publishing, audience reporting, and media production in the tools that handle them. Use fenbs when the missing piece is a shared record of the instructions, approvals, and work still to do.
