What Is a Niche on X?
A niche is the focused topic and audience your X account serves, such as "SaaS pricing for early-stage founders" or "fitness for busy parents". It answers a newcomer's question: what will I get if I follow this account?
Example
Two founders both post about startups. One posts about anything: news, memes, motivation, product updates. The other posts only about getting a B2B product to its first 100 customers, with numbers from their own company. The second account is easier to recommend, easier to follow and easier for X to show to the right people.
Why it matters for growth
- Followers know why they follow. A clear promise turns a single good post into a follow, because readers can expect more of the same.
- The algorithm learns who you are for. Posting consistently on a topic helps X's algorithm show your posts to people interested in it.
- Replies get easier. When you know your niche, you know which conversations to join, and your replies add real expertise.
- It sells. An audience gathered around one problem is a natural audience for the product that solves it.
A niche can widen over time. Start narrow enough to stand out, then add neighbouring topics once people know you for one thing.
How to find yours
Look for the overlap of three things: what you know from experience, what you enjoy talking about, and what a specific group of people wants to learn. Write it as one line, "I help [who] with [what]", and put it in your bio.

Frequently asked questions
Can I post about things outside my niche?
Yes, now and then. Personal posts make you human. Keep most posts on topic so new followers get what they came for.
How narrow should a niche be?
Narrow enough that you could name ten accounts in it and a reader instantly knows what you cover. You can widen later.
