Picking & Owning a Niche

Why narrow wins on Instagram, the niche selection framework that actually works, and when (rarely) to expand.

Lesson 1: Why Narrow Wins on Instagram

Instagram's algorithm groups users into topic clusters. The narrower your content, the cleaner your cluster signal — and the better your reach within the right audience.

The problem with broad accounts

A broad account ("lifestyle / business / productivity / wellness") confuses the algorithm. It can't decide which cluster you belong to. So it shows your content less to everyone.

A narrow account ("solo founder writing about indie SaaS") gets unambiguous categorization. The algorithm knows exactly who to show your content to. Reach to that specific audience is high; reach to others is irrelevant.

What this looks like in numbers

A broad account with 10K followers might reach 500 people per post. A narrow account with the same 10K followers might reach 1,500 — three times the reach to the right audience.

Why founders resist this

The fear: "If I'm too narrow, I'll run out of things to say."

Reality: A narrow niche, deeply explored, has more content than a broad one shallowly covered. Indie SaaS alone has more sub-topics than you can post about in 5 years.

The compounding benefit

Narrow accounts also benefit from:

  1. Easier follower decisions. A potential follower can predict what they'll get.
  2. Stronger word of mouth. "You should follow X — they're the indie SaaS person" is easier than "follow X for general business stuff."
  3. Better collaborations. Other niche accounts want to partner with clear-niche peers.
  4. Easier monetization. A 10K-niche audience is worth far more than a 100K-broad one.

Lesson 2: The Niche Selection Framework

Three questions decide your niche:

Question 1 — What can you talk about for 3+ years?

Niches that change every 6 months don't compound. You need a topic where you'll still find new angles in year three.

Bad niches:

  • Trend-driven topics ("the best AI tool right now").
  • News commentary (constant treadmill).
  • Generic "lifestyle."

Good niches:

  • Specific industries you understand.
  • Specific roles ("CFO at a Series A startup").
  • Specific lifestyles you live.
  • Specific crafts you practice.

Question 2 — Is there an audience for it on Instagram specifically?

Some niches don't have meaningful audiences on Instagram. Don't fight the platform's audience demographics.

Strong on Instagram:

  • Visual or process-based crafts.
  • Lifestyle and aesthetic-driven content.
  • Coaching, education, edutainment.
  • Beauty, fitness, food, travel.
  • Founder narratives (especially with visuals).

Weaker on Instagram:

  • Pure technical content (better on X, LinkedIn, YouTube).
  • Long-form analysis (better in newsletters).
  • B2B with no visual component.

If your niche fits Instagram, great. If it doesn't, choose another platform — don't fight the demographics.

Question 3 — Can you describe it in 5 words?

If you need a paragraph to describe your niche, it's too broad. Strong niches compress to:

  • "Indie SaaS founder building in public."
  • "B2B copywriter working with developer tools."
  • "Vegan recipes in 30 minutes."
  • "Productivity for ADHD entrepreneurs."

Each one is clear, specific, and a potential follower can predict what they'd get.

Testing your niche

A good niche-test: write 30 post ideas in 15 minutes. If you can't, the niche is too narrow. If you can write 300, it's probably too broad.

Lesson 3: When to Expand and When to Stay

Most accounts expand too early. Recognize the signs.

Stay narrow when:

  1. You're under 50K followers. Premature expansion dilutes positioning.
  2. You haven't fully covered your niche. If you've only made 30 posts, there's more to say.
  3. Engagement is healthy. If your audience is engaging well, the niche is working.
  4. You're known for X. When people refer to you in conversation, what's the X? If it's still consistent with your niche, stay.

Consider expanding when:

  1. You're past 100K and growth has plateaued. You've saturated your immediate niche.
  2. Your most engaged audience is asking about adjacent topics. They're telling you what they want next.
  3. You have something genuinely new to say in an adjacent space. Not chasing reach — pursuing real interest.
  4. Your business has evolved. Sometimes niche evolution follows business evolution.

How to expand without diluting

  1. Adjacent, not unrelated. Don't go from "indie SaaS" to "lifestyle." Go from "indie SaaS" to "indie SaaS + scaling teams."
  2. Layer in slowly. 90% original niche, 10% new direction for the first 90 days.
  3. Keep one core anchor. No matter what you add, your bio and pinned content stay anchored to your original niche.
  4. Watch your unfollow rate. If unfollows spike when you expand, the audience is telling you the expansion is wrong.

What never works

  1. Expanding to chase trends. "I'll add some AI content because that's what's trending now." Audience knows.
  2. Multiple unrelated niches in one account. Better to spin up a second account for the second niche.
  3. Expanding because growth is slow. Slow growth in a narrow niche usually means weak content, not too-narrow positioning.

Common myths

  1. "Niching down limits my growth." The opposite. Niching down accelerates it.
  2. "I'll lose followers if I'm too specific." Specificity earns followers; vagueness loses them.
  3. "All the good niches are taken." They're not. Niches are infinitely sub-divisible.

Action Steps

  1. Describe your current niche in 5 words. If you can't, your niche is too broad.
  2. Compare your last 30 posts to your stated niche. Are they consistent? If not, the niche has drifted.
  3. Tighten your bio and pinned post to match your niche if they don't already.

A narrow, well-owned niche is the foundation of every growing Instagram account. Get it right; everything else gets easier. Next lesson: collaborations.
