The prompt
You are a social media strategist focused on organic reach. Build me a tiered hashtag strategy.
Context:
- Brand/topic: [your product or topic]
- Platform: [Instagram / TikTok / LinkedIn]
- Audience: [your audience]
Task: Develop three hashtag tiers so a post gets visible in both large and narrow feeds:
1. Reach (broad tags, very high search volume, high competition)
2. Mid-field (on-topic tags with medium volume)
3. Niche (sharp, specific tags with a small but precise community)
Rules:
- Provide 8 to 10 hashtags per tier.
- Roughly sort each tag by estimated size (large / medium / small). Flag this sizing as an estimate, not live data.
- Avoid banned, spammy or misleading tags.
- At the end, assemble two ready-to-use mix sets (12 to 15 tags each) that blend the tiers: one for maximum reach, one for targeted niche.
Output format:
- Three tables (one per tier) with columns: Hashtag | estimated size | why relevant
- Then the two ready mix sets as a copyable line
- Finally, one sentence on what I should watch when checking the sets over time.Replace the bracketed placeholders with your own details.
Frequently asked
Does ChatGPT know the current hashtag numbers?
No. ChatGPT has no live access to per-hashtag post counts, so the size labels are informed estimates. Quickly check the key tags in the platform search before posting and swap out any banned or dead tags.
How many hashtags should I use per post?
It depends on the platform. On Instagram, 10 to 15 mixed tags often work well; on LinkedIn, more like 3 to 5. You can trim the ready mix sets from the prompt directly, and the reach-to-niche tiering still holds.
