If you usually get to the end of August and realise you have no September content planned — deep breath. We’ve got you.

September is your golden opportunity to show up with value, clarity and purpose to attract new people into your world, and build trust with your existing audience.

So here are 21 content ideas to help you plan smarter and make September your most strategic month yet.

Positioning Content Ideas

These ideas build authority, show your thinking, and separate you from every other “done-for-you social media support” person on the ‘gram.

1. If I wanted more sales in Q4, here’s exactly what I’d post in September.
   → People love a direct, “here’s the plan” post. Make it niche-specific to build even more trust and engagement.
2. A recent client win (but share what made it work)
   → Don’t just post the results you got for the client, tell the story of what was happening before, how you achieved the results and what that meant for the client. Help your audience see themselves in your story, too, so they can imagine what's possible if they work with you.
3. “You don’t need more content. You need this…”
   → A hot take about quality over quantity, strategy vs scrambling. People LOVE having a reason to do less, so give them one that actually works!
4. The most underused content type right now, and how to make it work.
   → Easy way to share value + spark engagement + subtly pitch a service.
5. This is the question I ask before I post anything — and you should too.
   → Position yourself as someone strategic and authoritative.

Timely, Seasonal Content Ideas

Tapping into what’s happening this month, but in a way that actually serves your audience.

6. Promoting a service?
   → Position it around the coming season. “Your autumn reset” or “Q4 prep pack”, rather than just a typical promotion. Timeliness helps people make decisions.
7. “This time last year…” –
   → Reflect and celebrate, show you grow too, with a throwback that reflects progress, lessons or results.
8. “September is the business owner's New Year” Share what you're doing differently this month
   → Use it to show leadership, self-awareness and relatability. Pitch your authority by showing how you're helping clients start over, too.
9. How to get your business ready for Black Friday / Christmas / Q4 launches
   → Getting people thinking about this early makes you look super organised and ready to help them.
10. Your Q4-ready checklist (with one thing people always forget)
    → Could be a carousel, Reel, or lead magnet CTA.

Behind-the-Scenes & Relatable Ideas

Use these to build connection and show personality, especially if your audience struggles to post consistently.

11. What’s on my to-do list this week (and what I’m ignoring)
    → Give people permission to prioritise things that will make an impact in their business.
12. A process I use that saves me hours every month
    → Show a process or tool you use to stay organised / plan ahead to build value without sounding salesy.
13. “If I were starting from scratch this September, here’s what I’d focus on”
    → Establishes you as a guide. Even for people just getting started.
14. The service I nearly stopped offering — and why I didn’t
    → Allows you to give real insight, while also building authority and trust to subtly sell a service your audience needs!
15. Behind the scenes of working with me.
    → People are nosey; this is like a freelancer's version of an unboxing! Show inside your business, your process is what's inside the box!

Engagement Boosters

Posts designed to spark saves, shares, clicks or comments — especially helpful if engagement has dipped over the summer.

16. September trend predictions (and how to jump on them early)
    → Showing you know what’s coming and you have an opinion positions you as an authority.
17. Hot take post about something you disagree with in your niche
    → Sets you apart from everyone else, saying the same old things.
18. Share your toolkit – the top 3 tools you're relying on for the next quarter
    → People love hearing about tools and processes, in case they can use them too (bonus points for using an affiliate link!)
19. Talk about why people don't engage with content – and how to fix it.
    → This is people's biggest bug bear with social media, build your own engagement by diving into it with your audience.

And finally, the no-brainer…

21. A reminder of how people can work with you this quarter, even if you’ve shared it before. This is the busiest time of year for so many businesses and can be one of the most lucrative periods for freelancers in the social media space!
