Why This Prompt Exists
Most hashtag strategies are random — copy-pasted from other posts.

You get:

  • hashtags that are too competitive (can’t rank)
  • hashtags that are irrelevant (wrong audience)
  • no mix of sizes (all large or all small)
  • hashtags that don’t match the post topic
  • missed discovery opportunities

But hashtag strategy is not random.

It is a mix of sizes and relevance.

  • Small hashtags (under 100k posts): easier to rank
  • Medium hashtags (100k-500k posts): balance
  • Large hashtags (500k+ posts): reach potential
  • Niche hashtags: highly targeted

Without a strategy, your hashtags don’t work.

This framework forces AI to build hashtag sets that maximize discovery.

The Prompt
Assume the role of an Instagram hashtag strategist who maximizes discovery.

Your task is to generate hashtag sets.

Generate:

1. NICHE HASHTAGS (5-7)
   - Highly specific to your niche
   - Under 100k posts (easier to rank)

2. MEDIUM HASHTAGS (5-7)
   - Broad but relevant
   - 100k-500k posts

3. LARGE HASHTAGS (3-5)
   - High reach potential
   - 500k+ posts

4. LOCATION HASHTAGS (2-3, if applicable)
   - City or region specific

5. BRANDED HASHTAG (1)
   - Your own unique hashtag

6. HASHTAG SET RECOMMENDATION
   - Which hashtags to use together
   - How many total (20-25 recommended)

INPUTS:

Your Niche:
[INSERT]

Post Topic:
[WHAT IS THE POST ABOUT?]

Target Audience Location:
[LOCAL / NATIONAL / GLOBAL]

Account Size (followers):
[SMALL (<1K) / MEDIUM (1K-10K) / LARGE (10K+)]

Competitor Hashtags (if known):
[LIST OR "UNKNOWN"]

RULES:
- Mix hashtag sizes (small, medium, large)
- Niche hashtags: under 100k posts (easier to rank)
- Use 20-25 hashtags total (Instagram's sweet spot)
- Location hashtags for local businesses
- Branded hashtag for community building
- Test different sets to see what works
- Don't use banned or spammy hashtags
How To Use It
  • Mix hashtag sizes — small (easier to rank), medium (balance), large (reach).
  • Niche hashtags should have under 100k posts — you have a chance to rank.
  • Use 20-25 hashtags total — Instagram's sweet spot for discovery.
  • Location hashtags for local businesses — city or neighborhood specific.
  • Branded hashtag for community building — encourage followers to use it.
  • Test different sets and track which perform best.
Example Input

Your Niche: Freelance productivity and business growth

Post Topic: How to raise freelance rates without losing clients

Target Audience Location: NATIONAL

Account Size: MEDIUM (1K-10K followers)

Competitor Hashtags: #freelancetips #freelanceadvice #freelancecommunity

Why It Works
Most hashtag strategies are random.

This framework improves outcomes by forcing:

  • niche hashtags (targeted reach)
  • size mixing (balance of rankability and reach)
  • location hashtags (local discovery)
  • branded hashtags (community building)
  • strategic recommendation (execution)

Great hashtag strategies don't guess — they use a mix of sizes and relevance.
