Hello! Welcome to your next lesson in the Practical Social Media Content Creation module.
In our last lesson, we focused on crafting compelling captions using the Hook-Value-CTA framework. You learned how to write text that grabs attention and encourages your audience to act. But even the best caption needs help getting discovered by new audiences. That's where hashtags come in.
This lesson will teach you how to select effective hashtags to increase content discoverability on platforms like Instagram and TikTok. We will explore what hashtags do, how to find the right ones for your content, and the specific best practices for both Instagram and TikTok. By the end, you'll be able to strategically use hashtags to help your content reach the right people.
The True Role of Hashtags: Content Categorization
First, let's set the right expectation. In the early days of social media, hashtags were the primary way to get more views. Today, algorithms are much smarter. They analyze your visuals, your caption text, and user behavior to understand your content.
So, are hashtags still important? Absolutely. But their role has evolved. Think of them less as a magic trick for views and more as a crucial tool for categorization. They give the algorithm clear signals about your content's topic, helping it show your post to the most relevant audience.
To understand this modern perspective on hashtags, let's watch a short clip.
Why Your Instagram Hashtags Aren't Working & How To Fix Them
The video 'Why Your Instagram Hashtags Aren't Working & How To Fix Them' from the Modern Millie channel does an excellent job of explaining the current role of hashtags. It clarifies that they are a piece of the puzzle, not the whole solution.
Please watch from the beginning to 02:45, and then from 20:51 to 22:57. The creator explains that hashtags help the algorithm understand your content rather than directly guaranteeing views. She also emphasizes that great content is the most important factor for success.
As the video highlights, your content's quality is paramount. Hashtags support great content; they don't save bad content. A well-chosen set of hashtags helps your well-crafted post (with its Hook, Value, and CTA!) find its ideal audience on search pages, explore feeds, and the TikTok "For You" page.
The Core Strategy: A Mix of Popular and Niche Hashtags
The most effective hashtag strategy involves using a balanced mix of hashtag types to maximize both broad reach and targeted engagement. The two main categories are:
- Popular (or Broad) Hashtags: These are very general tags with millions of posts (e.g.,
#fitness,#food,#marketing). They can expose your content to a massive audience, but it's also easy to get lost in the noise. - Niche Hashtags: These are much more specific to your industry, topic, or target audience (e.g.,
#beginnerworkouttips,#veganpastarecipe,#pharmacymarketing). They have a smaller, but more dedicated and engaged, audience.
The goal is to use both. A popular hashtag gives you a shot at wide visibility, while niche hashtags ensure you're connecting with people who are deeply interested in what you have to say.
The following video provides a great walkthrough of this concept and shows you how to start finding these different types of hashtags directly on TikTok.
TikTok Hashtags Strategy for Viral Growth (2024)
The HubSpot Marketing video, 'TikTok Hashtags Strategy for Viral Growth,' uses a simple 'cookie business' example to demonstrate how to find and mix popular and niche hashtags.
Watch from 02:12 to 03:59. Pay attention to how they differentiate between a popular tag like #cookies and more specific, niche tags like #holidaycookies or #sugarcookierecipe.
How to Research and Select Your Hashtags
Now for the practical part: how do you find the right hashtags for each post? Avoid guessing. A data-driven approach will always yield better results.
1. Strategic Brainstorming
Before you even search for a hashtag, you should have a clear idea of your content strategy. This process connects directly back to defining your target audience, which we covered in the first module.
The "Modern Millie" video you watched earlier introduces a fantastic framework for this.
Why Your Instagram Hashtags Aren't Working & How To Fix Them
Let's return to 'Why Your Instagram Hashtags Aren't Working & How To Fix Them.' This section walks through a strategic exercise to generate content ideas and relevant keywords before you even think about hashtags.
Watch the following three segments: Establish Your Strategy (03:45 - 06:54): Observe the brainstorming process (Industry, Audience, Pain Points, Solutions, Topics). Imagine doing this for a pharmacy targeting new mothers or elderly patients. Targeted Content Ideas (09:47 - 12:05): See how keywords from the strategy session are turned into specific content ideas. Three Starting Points (17:08 - 18:15): This is a key takeaway. For any post, you can find relevant hashtags by describing: the visual, the topic, and your profile/brand.
This strategic approach ensures your hashtags are always relevant to your audience and your goals. When you post, you can pull hashtags from three buckets:
- Visuals: What is literally in the photo/video? (
#pharmacist,#pillbottle,#labcoat) - Topic: What is the caption or video about? (
#healthtips,#medicationsafety,#winterwellness) - Profile: Who are you? (
#communitypharmacy,#digitalhealth,#yourpharmacybrandname)
2. On-Platform Research
Once you have your keywords, use the platforms themselves as powerful research tools.
- TikTok: Use the search bar and filter by "Hashtags." It will show you a list of related hashtags and their view counts.
- Instagram: Searching for a hashtag will show you its post volume. It also suggests related hashtags at the top of the search results page.
Also, look at what your competitors and other leaders in your niche are using. Don't just copy them, but analyze their strategy. What popular tags do they use? What niche communities are they tapping into?
3. Using Tools
For more advanced research, you can use dedicated tools.
- TikTok Creative Center: This free tool from TikTok lets you find trending hashtags by industry and region, with detailed analytics.
- Third-Party Generators: Many tools exist that can suggest hashtags based on a keyword.

Platform-Specific Best Practices
While the core strategy is similar, the optimal number and placement of hashtags differ between Instagram and TikTok.

Instagram Hashtag Strategy
- Quantity: Aim for 5-15 highly relevant hashtags. While you can use up to 30, quality is more important than quantity. Using too many can look spammy. The article "Instagram Hashtag Strategy 2024" suggests that posts with around 9 hashtags often see good engagement.
- Mix: Use a combination of popular (1-2), semi-popular (3-5), and niche/branded (3-5) hashtags. This is detailed in the Blare Media article below.
- Placement: You can place them at the end of your caption or in the first comment immediately after posting. Both work for discoverability.

The article 'Instagram Hashtag Strategy 2024' provides clear, actionable advice tailored for Instagram.
Please read the sections 'What is the Best Instagram Hashtag Strategy in 2024?', 'How Many Hashtags Should I Use on Instagram?', and 'Quick Tips for Using Hashtags...'. Focus on the example of mixing hashtag types and the recommended number of hashtags.
TikTok Hashtag Strategy
- Quantity: Less is more. Aim for 3-5 highly relevant hashtags. TikTok's algorithm is very powerful and relies on a few precise signals.
- Mix: Include a mix of broad and niche tags. It's also common to use a trending hashtag if it's relevant to your video.
- Placement: Hashtags must be in the video caption. The algorithm does not prioritize hashtags placed in the comments.
TikTok Hashtags Strategy for Viral Growth (2024)
Let's revisit the HubSpot video, which focuses specifically on TikTok best practices.
Watch from 03:59 to 05:38. This segment covers the best placement for your hashtags and the optimal number to use for TikTok.
Test your understanding!
Imagine you are creating a short TikTok video for a community pharmacy. The video quickly shows three "myths vs. facts" about sunscreen. The goal is to educate viewers and promote the pharmacy's range of SPF products.
Based on what you've learned, propose a set of 3-5 hashtags for this video. Identify which are broad and which are niche.
Show answer
Here is one possible combination. Your answer might vary, but it should demonstrate the same strategic thinking.
#sunscreen(Broad/Popular): This targets a huge audience interested in the general topic.#skincaretips(Broad/Popular): This captures people looking for general skincare advice.#sunscreenmyths(Niche): This is highly specific to the video's content and will attract a very engaged audience.#dermatologytips(Niche): While you're a pharmacy, this tag taps into a community that trusts scientific advice about skin, which aligns with a pharmacist's expertise.#healthyskin(Broad/Popular): A positive, benefit-oriented hashtag.
A good set would be something like: #sunscreen #skincaretips #sunscreenmyths #healthyskin. This includes 3 popular and 1 niche tag, which is a solid strategy.
Conclusion
You now have a complete toolkit for crafting the text portion of your social media posts. You know how to write a compelling caption with a Hook, Value, and CTA, and you know how to select and apply strategic hashtags to help that content get discovered.
Key Takeaways:
- Hashtags are primarily for content categorization, helping the algorithm show your post to the right audience.
