Best AI Prompts for Facebook Posts (2026)

Prompts for Facebook posts#

Act as a social media copywriter for [DESCRIBE YOUR BRAND AND AUDIENCE]. Write a Facebook page post announcing [PASTE YOUR PRODUCT OR UPDATE DETAILS]. Open with a one-line hook, give three short bullet points taken only from the details I pasted, and end with one clear call to action and the link [PASTE YOUR URL]. Write three variants of different length and tell me which opening line you would test first.

Act as a community manager for a Facebook group of [DESCRIBE YOUR GROUP MEMBERS]. Write a discussion post asking members about [PASTE YOUR TOPIC OR QUESTION], phrased so it can be answered in one or two sentences. Do not ask people to like, share or tag friends. Add two follow-up comments I can post if replies are slow.

Act as a marketer turning a real customer story into a Facebook post. Use only this customer feedback and the facts around it: [PASTE THE CUSTOMER'S EXACT WORDS AND WHAT THEY CONFIRMED YOU MAY SHARE]. Keep the customer's quote verbatim, add no result or number that is not in the text, and write a short setup and a closing line. List any claim you could not support from the text.

Act as a brand voice editor. Here are three of our past Facebook posts that performed well: [PASTE THREE POSTS]. Match their tone and length to write a short post promoting [PASTE YOUR ARTICLE TITLE AND SUMMARY]. Say what the article actually covers, and make the link text match what the reader will find.

Act as an educator in [DESCRIBE YOUR FIELD]. Turn [PASTE YOUR NOTES OR ARTICLE] into a Facebook post of three practical tips, each in one or two sentences, written for people who are [DESCRIBE THE READER'S LEVEL]. End with a question about their experience, not a request to share. Keep every fact from my notes and add none.

What to add to any Facebook post prompt#

• Where it will appear. Say whether it is a page post, a group post or an ad. Anthropic advises adding context or motivation behind instructions so the model can give more targeted responses.
• Your real facts. OpenAI advises supplying facts the model cannot know, such as product details and approved claims, and Google advises supplying background material so the model does not rely on generic output.
• Two or three past posts you like. Anthropic calls examples one of the most reliable ways to steer tone, format and structure, and suggests 3 to 5. Google advises varied examples and warns that too many can cause overfitting.
• Hard limits. Length, required call to action, banned phrases and claims you cannot make. OpenAI and Google both advise stating constraints and the output format directly.
• What not to do, stated as what to do. Anthropic advises saying what you want instead of what to avoid, so write "ask for answers in a sentence" rather than only "no engagement bait".
• A request for variants. Ask for three versions so you can test them yourself; the model cannot know how your audience will respond.

A worked example#

Act as a community manager for a Facebook group of home bakers who sell at local markets. Write a discussion post asking members how they price sourdough loaves when flour costs rise. Phrase it so it can be answered in one or two sentences, mention that I will share a summary of the answers next week, and do not ask people to like, share or tag friends. Give two variants (under 60 words and under 100 words) and add two follow-up comments I can post if replies are slow.

A good result for this task:

• Asks one concrete question, not several, and a member can answer it in a sentence.
• Contains no request to like, share, tag or comment to unlock anything.
• Promises only what you will do (the summary), and you must then actually do it.
• Sounds like a member of the group, not an advertisement.
• Gives the two lengths you asked for, so you can pick one.

Also check every fact, price, date and link against your own records, and read the post as a member would.

Limits of this guide#

This page shows how vendors advise prompting for copy and which Meta and FTC rules apply to the output. We did not test the prompts, did not measure reach or engagement for any wording, and did not find Meta's Advertising Standards pages readable, so paid-ad rules are not covered. Meta's policies change; confirm the current text before relying on a summary. This is general information, not legal advice.
