Hashtag Research and Content Repurposing
Two skills separate efficient content creators from everyone else: smart hashtag strategy and the ability to turn one idea into content for every platform. AI handles both of these extremely well. This lesson shows you how.
Hashtag Research with AI
Why Hashtags Still Matter
Hashtags help new people discover your content. They work differently on each platform:
| Platform | Hashtag Behavior |
|---|---|
| Up to 30 allowed; 3-5 targeted hashtags often outperform 30 generic ones | |
| 3-5 hashtags recommended; placed at the end of the post | |
| X (Twitter) | 1-2 hashtags max; more than that reduces engagement |
| TikTok | 3-5 hashtags; mix of niche and trending |
The Hashtag Research Prompt
I'm posting an Instagram post about meal prep tips for busy professionals. Suggest 15 hashtags organized into three groups:
- 5 broad/popular hashtags (500K+ posts)
- 5 medium hashtags (50K-500K posts)
- 5 niche hashtags (under 50K posts)
Explain why mixing these sizes matters.
Why the mix matters: Broad hashtags have massive competition but high visibility. Niche hashtags have less competition, so your post is more likely to be seen. Medium hashtags balance both. Using all three gives you the best chance of discovery.
Platform-Specific Hashtag Prompts
For LinkedIn:
Suggest 5 LinkedIn hashtags for a post about remote team management. Focus on hashtags that professionals and hiring managers follow.
For X:
Suggest 2 hashtags for a tweet about AI productivity tools. Keep them short and commonly used.
For Instagram Reels:
Suggest 5 hashtags for an Instagram Reel about home office setup ideas. Mix trending and evergreen hashtags.
Building a Hashtag Library
Instead of researching hashtags for every post, build a reusable library:
I'm a graphic designer sharing design tips on Instagram. Create a hashtag library organized by content type:
- Tutorial posts (5 hashtags)
- Portfolio/showcase posts (5 hashtags)
- Behind-the-scenes posts (5 hashtags)
- Industry news/opinion posts (5 hashtags)
- Client work posts (5 hashtags)
Save this library and rotate through the sets to keep your hashtag usage varied.
Hashtag Mistakes to Avoid
| Mistake | Why It Hurts | Fix |
|---|---|---|
| Using only popular hashtags | Your post drowns in millions of others | Mix in niche hashtags |
| Using irrelevant hashtags | Hurts algorithm trust and attracts the wrong audience | Every hashtag should match the post topic |
| Using the same hashtags on every post | Platforms may flag this as spam | Rotate between 3-4 hashtag sets |
| Using banned hashtags | Can shadowban your entire post | Check hashtags before using them |
Ask AI: "Are any of these hashtags commonly banned or flagged on Instagram? [paste your list]"
Content Repurposing with AI
Repurposing means taking one piece of content and adapting it for multiple platforms. It is the single most efficient content strategy you can use.
The One-to-Many Framework
Start with one "pillar" piece of content and turn it into multiple posts:
Blog post or long-form content
├── LinkedIn post (key insight)
├── X thread (step-by-step breakdown)
├── Instagram carousel (visual summary)
├── Instagram caption (personal take)
├── Email newsletter snippet
└── Short-form video script
The Repurposing Prompt
Here is a blog post I wrote: [paste content]
Repurpose this into:
- A LinkedIn post (300-500 words, professional tone, hook opening)
- A 5-post X thread (under 280 characters each)
- An Instagram carousel script (8 slides, minimal text per slide)
- An Instagram caption (conversational, with a question at the end)
Adapt the tone and format for each platform. Keep the core message consistent.
Repurposing from Short to Long
You can also go in reverse—turn a tweet or short post into longer content:
This tweet performed really well: "[paste tweet]"
Expand this into:
- A full LinkedIn post with more detail and examples
- A 7-slide Instagram carousel with actionable steps
- Three follow-up tweet ideas that continue the conversation
Repurposing Across Time
Reuse your best content by updating it:
Here is a post I published 3 months ago that performed well: [paste post]
Rewrite this with a fresh angle, updated examples, and a different hook. Keep the core message the same but make it feel new.
Platform Adaptation Cheat Sheet
| Original Format | X | ||
|---|---|---|---|
| Blog post | Carousel (key points) | Long post (one insight) | Thread (step-by-step) |
| Podcast episode | Quote graphic + caption | Key takeaway post | 3-5 highlight tweets |
| Video | Caption from script | Lesson learned post | Best quote as tweet |
| Customer testimonial | Story highlight + caption | Case study post | Short endorsement tweet |
| Email newsletter | Carousel or single post | Share the main tip | Tease with a hook tweet |
Putting It All Together
Here is a weekly workflow combining hashtags and repurposing:
- Monday: Write or identify your pillar content for the week (a blog post, video, or detailed social post)
- Tuesday: Use AI to repurpose it into platform-specific posts for the week
- Wednesday: Use AI to generate hashtag sets for each post
- Thursday-Sunday: Schedule and publish
This approach means you only need one good idea per week to stay active across multiple platforms.
Key Takeaway
Smart hashtag research and content repurposing are the two biggest time-savers in social media. Use AI to build hashtag libraries organized by content type, and turn every piece of content into posts for multiple platforms. In the final lesson, you will put everything together into a complete AI-powered social media workflow.
