Social media used to be about who you knew. You followed friends, family, and a few brands, and your feed showed you what they posted. That era is over. Today the biggest platforms are not built on your social connections. They are built on your interests.
If you are building a personal brand or a business brand, that shift changes almost everything about how you should set up your accounts and what you should post.
From a social graph to an interest graph
For years, platforms ran on what the industry calls the social graph: the web of people you were connected to. Your reach depended on how many people followed you.
TikTok changed the game by ignoring that almost completely. It shows people whatever keeps them watching, whether they follow the creator or not. It worked so well that Instagram, Facebook, YouTube, and X all moved the same direction. Now a large share of what people see in their feeds comes from accounts they have never followed.
This is the interest graph. The platform is not asking "who are this person's friends?" It is asking "what is this person into, and what will hold their attention next?"
What that means for anyone building a brand
Every time you post, the platform runs a small test. It shows your content to a group of people it thinks will care, watches how they respond, and then decides whether to show it to more people like them.
For that test to work, the platform has to understand what your account is about. The clearer your topic, the faster it can find the right audience. Followers still matter, but they matter less than being easy to categorize.
The multi-niche problem
Here is where a lot of people get stuck. Most interesting people and businesses are not one-dimensional. You might care about business, family, faith, sports, and politics. Your company might serve two very different customers.
When you put all of that on one account, two things go wrong:
- The algorithm gets confused. A comedy clip, then a market update, then a political take sends mixed signals. The platform does not know who to show your content to, so it shows it to fewer people.
- Your audience gets confused. Someone who followed you for funny videos scrolls past your crypto post, or unfollows. Low engagement tells the algorithm your content is not landing, and your reach drops across the board.
Mixing niches does not make your account more interesting. It makes it harder to recommend.
The fix: one niche per account
If your brand covers more than one topic, split it. Create a separate account for each niche, and make content that is built specifically for that audience.
I do this with my own brand. I run four sets of channels across Facebook, Instagram, and TikTok:
- @thejonwillis for observational comedy, my main channel
- @thejonwillisbusiness for strategy, entrepreneurship, and building companies
- @thejonwillisonchain for blockchain and crypto
- @thejonwillisreport for political commentary
Each audience gets exactly what it signed up for. The comedy fans never have to sit through a token discussion, and the business followers are not caught off guard by a political post. Each account has a clear identity, so each one is easier for the platform to recommend.
How to set up a multi-niche brand
- Pick your niches carefully. Start with the two or three topics you can post about consistently. You can always add more later.
- Use one naming system. Keep your main name and add the topic, like @yourname plus business, plus fitness, plus food. People instantly know it is you and what each account covers.
- Keep the look consistent. Use the same photo style, colors, and logo across every account so they read as one brand family.
- Cross-link in every bio. Each account should point to the others and to your website. Someone who finds your business account should be one tap away from your comedy, and the reverse.
- Make native content for each niche. Do not post the same video everywhere. The tone, format, and length should fit each audience. A business audience might want a 60-second breakdown. A comedy audience wants the punchline in the first three seconds.
Be honest about the workload
More accounts means more content. That is the trade-off. I do my own posting, so I know the time it takes. A few things make it manageable:
- Batch your content. Film several pieces for one niche in a single session.
- Repurpose ideas, not posts. One insight can become a business tip on one account and a joke on another.
- Start small. Two focused accounts will outperform five neglected ones.
Tie it all back to a home base
Separate accounts help you grow, but every audience should have a way to find the whole picture. That is what your website is for. It is the one place that connects every niche, tells your full story, and gives people a direct way to reach you, no matter which platform they came from. Followers on any app are rented. Your website and your email list are owned.
The bottom line
Social media is now interest media. The platforms reward accounts that are clear about what they are and who they are for. If your brand has more than one side, do not water it down by mixing everything together. Give each niche its own home, feed it content made just for that audience, and connect them all back to you.
