Confession time: I love a Facebook group.
My local community page, my mum’s group and my favourite buy-and-sell fashion group are all part of my daily scroll.
I don’t use Facebook to see what my high school friends are doing anymore, I’m there for groups.
For a lot of people, especially millennials and older audiences, Facebook groups have become one of the few reasons they still open the app. They’re practical, specific and often surprisingly useful. Less “look at my holiday album” and more “does anyone know a good plumber who will actually call me back?”
From a marketing perspective, local community groups are basically the modern version of the noticeboard at the local shops. You know the one. A handwritten flyer, a few tear-off phone number tabs and maybe a lost dog poster.
Except now, it’s online, searchable and full of people actively asking for recommendations.
It’s where locals go when they need a hairdresser, dog walker, cleaner, plumber, mechanic, gardener, mortgage broker, physio, cake maker or just someone who “knows a guy”.
For small businesses, this can be incredibly powerful. You’re not interrupting people with an ad while they’re trying to watch a reel. You’re showing up in a space where people are already looking for help, advice and trusted local recommendations.
Niche interest-based groups
Then there are niche groups.
These are the groups people join because they have a specific interest, problem, hobby, public figure, brand or identity. Think skincare groups, home renovation groups, parenting groups, business owner groups, fashion buy-and-sell groups, suburb groups, fitness groups, travel groups and every strangely specific corner of the internet in between.
There are also fan-style communities built around well-known people, brands and creators. For example, the RecipeTin Eats Appreciation community has more than 112,000 members. That’s a huge audience of people gathering around one shared interest: cooking, recipes, meal ideas and the very specific joy of knowing someone else is also making the same satay chicken tonight.
People usually join these groups because they want information, recommendations, opinions or lived experience from real people. They might be troubleshooting a problem, looking for advice before they buy something, trying to improve a skill, or wanting proper guidance from someone who actually knows what they’re talking about.
And that’s what makes these groups so valuable.
A niche Facebook Group is not just a collection of people. It’s a collection of people who have self-identified as being interested in a particular topic. They’re raising their hand and saying, “I care about this.”
For businesses, experts and creators, that creates a real opportunity to show up with value. Not just to sell, but to support people’s efforts, answer questions, provide useful advice and build trust in a space where people are already engaged.
From a marketing point of view, that is pretty powerful.
Using Facebook groups as a marketing tool
1. Join relevant local or niche groups
This is the simplest place to start.
Join the groups your ideal customers are already in. That might be your local suburb group, a community noticeboard group or a niche group related to your product or service.
But don’t just join and start flogging your business straight away. That is the fastest way to annoy everyone and potentially get booted by the admin.
Instead, pay attention. Look for the kinds of questions people ask. See what recommendations come up again and again.
Understand the language people use when they talk about your industry.
Then, where it is allowed and relevant, contribute.
Answer questions. Offer helpful advice. Respond when people are asking for services like yours. Be useful before you try to sell.
2. Post about your services where allowed
Many groups have specific promo days or allow business posts under certain rules. Use these opportunities properly.
A good group post should not just say, “Hi, I’m a business, book now.”
Make it helpful, clear and searchable. Think about what people might search in the group later. For example:
“Hi Toowong community, just putting my hand up and letting you know I’m a plumber based in Toowong who can help with blocked drains, burst pipes, toilets, leaking taps and emergency plumbing. If you need help, please send me a text on 04xx xxx xxx and I’ll get back to you.”
Or:
“Hi everyone! I’m Sarah, I’ve just moved into the area and I’m a hairdresser who has a salon on Sample Road. I have over 10 years of experience and I specialise in lived-in hair colours, coppers, blondes and my lovely new salon has comfy massage chairs and a yummy drinks menu! To welcome new clients I’m offering discount hair packages for 20% off all my services.”
The beauty of group posts is that people often search within groups before asking a question. So even if your post doesn’t get a flood of comments on the day, it can still be found later by someone actively looking for your service.
3. Create your own group
For some businesses, creating your own Facebook Group can be a smart move.
This works best when your business naturally has a community, interest or education angle. For example, a salon could create a local hair tips group. A turf business could create a lawn care group for South East Queensland homeowners. A finance broker could create a property advice or small business finance group.
A great example of this is Property Talk Australia, which has more than 17,000 members and was created by RealWay Finance. RealWay Finance created and manages the group and offers mortgage broking services to members, but the group itself isn’t just a stream of sales posts.
Eric, who manages the group, regularly posts insightful and conversation-provoking content around interest rates, the Australian property market and relevant news. This gives members a reason to engage, ask questions and keep coming back, while also positioning the business as a trusted voice in the space.
That’s the key with creating your own group. It cannot just be a sales page in disguise. People need a reason to join and stay.
You need to provide value, start conversations and manage the community properly. That means approving members, moderating posts, answering questions and keeping the group active.
And yes, if you are running the group, you also get to protect the space. You probably don’t need to approve every direct competitor who wants to wander in and start quietly poaching your members.
4. Sponsor an existing group
If there’s already a popular group with an active audience, sponsoring it can be a clever option.
Some group admins offer paid sponsorships where they’ll pin your business, mention you in relevant threads, recommend you when people ask for your service, or allow regular promotional posts.
This can work well because the trust already exists. The group admin has built the community, and their recommendation can carry more weight than a standard ad.
The trick is to make sure the group is genuinely active and aligned with your audience. A group with 30,000 members but no real engagement is not necessarily better than a group with 3,000 local members who ask for recommendations every day.
Facebook Groups aren’t the only community play
Reddit is another platform worth considering, especially because its SEO visibility is ridiculously strong.
If you’ve ever Googled a very specific question and ended up on a Reddit thread from three years ago with 87 comments and one person giving the exact answer you needed, you’ll know what I mean.
For businesses and experts, Reddit can be useful because people are often asking very specific questions and looking for honest, experience-based advice. That might be in a niche subreddit related to your industry, or in your local city subreddit where people ask for recommendations, troubleshooting help and local opinions.
The key is not to barge in with a sales pitch. Reddit users can smell that from a kilometre away and they will absolutely let you know about it.
Instead, look for threads where people are asking questions related to your expertise and respond with actual value. Share advice, explain your thinking, be transparent and only mention your business where it is genuinely relevant and allowed by the subreddit rules.
Done well, it builds visibility, trust and authority. And because Reddit threads often rank well in Google, those answers can continue working long after you post them.
Substack
Another option to consider, especially if you’re building a personal brand around a niche topic, is Substack.
Substack gives you a place to publish longer-form thinking, insights and commentary without having to rely entirely on social media algorithms. It works particularly well when you have strong opinions, useful expertise or a clear point of view on a specific subject.
The benefit is that you’re not just posting a quick update that disappears in the feed. You’re building a library of useful content that shows how you think.
Over time, this can help position you as a trusted voice in your space. It can support your personal brand, give you content to repurpose across LinkedIn and social media, and create a stronger reason for people to follow you beyond one-off posts.
It’s not for every business, and it does take consistency. But for experts, founders and niche service providers who want to build authority, it can be a very smart channel to consider.
