Social Media Post Ideas: 30 Evergreen Formats + Idea Radar

It’s 7 pm, the calendar says “post today”, and your head is empty. You open the feed “for inspiration”, close it forty minutes later with two memes from other people and no idea of your own. Everyone who has run an account for longer than a month knows the feeling, and it almost never means you have nothing to say.

Ideas run out for three reasons: no list of formats (every post is invented from scratch, like the first one), no sources (topics come from your head, and by Thursday your head is empty), and no idea bank (the thought that flashed by on Tuesday in the shower is gone by Friday). All three are fixed by a system, not by inspiration.

Below: 30 formats that work in any niche, five sources that never run dry, and a way to put idea hunting on rails so the blank page stops happening.

Diagnose first: what exactly is missing

Before you grab formats, check one thing: do you know who you’re writing for and why? If the account is “for everyone” and exists “because you should have one”, no list will help: you’ll have posts, but no response. One sentence, “we help [whom] with [what] better than [the alternative]”, should be written down before you open the formats. How to turn it into recurring columns and a schedule is covered in our content plan template.

30 formats that don’t go stale

Examples are for three typical accounts: a coffee shop in Austin, a stretching studio in Manchester, and a bookkeeping service for freelancers. Swap in your own business; the format stays the same.

Expertise: show you know your craft

1. A customer mistake, explained. “Three reasons your home cappuccino tastes sour.”
2. Before/after with the how. Not two photos but what happened between them and how long it took.
3. Mini how-to. 5–7 steps someone can repeat today: “How to check in 10 minutes whether you’ve missed a quarterly tax deadline.”
4. Myth busting. “Stretching doesn’t make muscles weaker, and here’s why coaches keep saying it does.”
5. One term in plain words. One industry term per card. Bookkeepers have hundreds: VAT, estimated tax, write-off.
6. Checklist. “7 questions to ask a studio before buying a membership.”
7. A vs B comparison. Ethiopian vs Brazilian beans, sole proprietor vs LLC, group vs one-on-one, with an honest “who needs which”.
8. Answer to a DM. The most honest format: the question was already asked, so dozens of silent followers have it too.

Behind the scenes: show how it’s made

9. A day in the life. The coffee shop at 6:30 am, before the first customer.
10. How we made a decision. Why the latte went from $4.50 to $5, with the math.
11. A failure and the lesson. The batch of beans you had to write off. People trust those who admit mistakes.
12. Tool of the day. What you use and why, from a tamper to your invoicing app.
13. Team. Not “our friendly staff” but one person and one story: how a barista arrived from a career in IT.
14. Business numbers. Cups per day, clients per month, share of returning customers. Openness is rare, so it hooks.

Engagement: give a reason to reply

15. A contrarian take. “Morning stretching is overrated”, with arguments.
16. Pick one of two. Two cup designs, two schedules, two service names; the audience votes.
17. Finish the sentence. “The perfect morning starts with…” works on Threads and in Reels comments.
18. Spot the mistake. “Find what’s wrong in this invoice.”
19. Pain-point poll. “What annoys you most about accountants?” You’ll also collect a month of topics.
20. Reply to a comment. A screenshot of a great (or angry) comment and a full-length answer.

Selling without pushing

21. A case with numbers. Client came with problem X, we did Y, they got Z. No “results may vary” in tiny print.
22. Review plus context. Not a “great service!” screenshot but a story: what it was like before, what changed.
23. What’s inside the service. Break the membership into parts; people don’t buy what they don’t understand.
24. Common objection, answered. “Too expensive” → what an hour of your time spent on DIY bookkeeping costs.
25. Where the price comes from. What makes up a $5 latte: beans, milk, rent, wages.

Timely: tied to the moment

26. Reaction to industry news. Tax rules changed for freelancers; explained in three paragraphs on the day.
27. Season and calendar. Back to school, Black Friday, quarter end; every niche has its dates.
28. A trend, your way. A Reels audio, a Threads format, but with your own content, not a copy.
29. Monthly recap. What got done, what didn’t, what’s next.
30. Announcement with a reason. Not “new product!” but why it exists and who it’s for.

Each format is a column in your calendar. Thirty formats across four platforms is a quarter of content without repeats if you post one a day.

Five sources that never run dry

Formats are the “how”; sources are the “what about”. Keep at least three within reach:

• DMs and comments. Every question asked is a topic. Keep a “customer questions” note and add to it the moment the question arrives.
• Industry media and niche Telegram channels or newsletters. Not for reposting but for reacting: news plus your opinion equals a post your competitors don’t have. An RSS reader or an idea feed gathers such material every morning so you don’t scroll ten sources.
• Search suggestions. Type “stretching” into Google and see what autocomplete adds. Those are real queries, not your guesses.
• Your own analytics. Your best posts of the last three months aren’t an accident. Repeat the format with a new topic.
• Competitors and adjacent niches. Not to copy but to find the gap: what everyone is silent about while customers keep asking.

The idea bank: so the idea survives until publishing

There are more ideas than it seems; they just get lost. One rule: any thought is written into one place within a minute. A phone note, a spreadsheet, your Saved Messages in Telegram, doesn’t matter, as long as it’s one place.

Minimal row structure: topic, format (number from the list above), platform, source. Once a week, 20 minutes: go through the bank, pick 5–7 ideas for next week, put them into the calendar. How to spread posts across slots and platforms is covered in the cross-posting guide.

After a month of this you’ll have 40–60 ideas in the bank, and the problem flips: finding time to publish them all.

AI as a radar, not an author

The most useful role for a language model here is not writing the post but multiplying angles. Give the model one piece of industry news or one customer question and ask for ten topics in different formats: breakdown, myth, checklist, contrarian take, case. You’ll throw away eight and keep two, and that’s two ideas in a minute instead of forty minutes of scrolling.

What the model needs to know so the options aren’t “about everything and nothing”: your niche, your city, who the customer is, what you sell, what you don’t do. Without it you get “5 productivity tips”. With it you get “why freelancers overpay taxes by choosing the wrong filing status”. How to assemble that context, and why generated text still needs editing, is in our piece on AI-written Instagram posts.

When this won’t work

• No positioning. Formats will give you posts, but not followers: the audience won’t understand why to follow.
• Your audience isn’t on the platform. Threads ideas are useless if your customers live in Telegram. Platform first, formats second.
• Ideas exist, time doesn’t. Then the problem isn’t ideas but production: look at automating the routine, not at new lists.

If you’d rather have the sources and the radar run without you, Repost21 has an Idea Feed built from RSS, Telegram channels and industry sites: drafts from fresh material every morning, with the Luna AI assistant suggesting angles in your tone. The Free plan is enough to see whether that rhythm suits you.
