Hashtags on LinkedIn: Complete Guide on How to Use Them

Hashtags can increase your reach by up to 30%. But used wrong, they can limit your visibility.

How Hashtags Work on LinkedIn

The Algorithm and Hashtags

1. Users follow hashtags of interest
2. Your post appears in the feed of those who follow those hashtags
3. The algorithm also uses hashtags to categorize your content

Hashtags vs. Reach

Hashtag use	Impact on reach
0 hashtags	Neutral
3-5 hashtags	+20-30%
6-10 hashtags	+10-15%
10+ hashtags	Can look like spam

How Many Hashtags to Use

Recommendation

3 to 5 hashtags is ideal.

• 1-2 broad hashtags (high volume)
• 2-3 specific hashtags (low competition)

Example

#marketing (broad - 26M followers)
#digitalmarketing (medium - 5M followers)
#contentmarketing (specific - 200K followers)

Types of Hashtags

1. Industry Hashtags

About your sector:

• #technology
• #fintech
• #healthcare
• #education
• #retail

2. Topic Hashtags

• #leadership
• #productivity
• #innovation
• #entrepreneurship
• #career

3. Community Hashtags

Where to Put Hashtags

Option 1: At the End (Recommended)

[Your post here]

#marketing #linkedintips #content

Option 2: In the Text

My journey in #entrepreneurship started 10 years ago...

Option 3: In the First Comment

Works, but has less reach than in the original post.

Common Mistakes

1. Irrelevant Hashtags

Don't use #motivation on an accounting post just because it's popular.

2. Too Generic Hashtags

#business has billions of posts. Your content gets lost.

3. Made-Up Hashtags

#myamazingpost has no followers.

4. Too Many Hashtags

More than 10 hashtags = spam-like appearance.

5. Banned Hashtags

LinkedIn bans some hashtags (usually for spam or inappropriate content).

How to Research Hashtags

Method 1: LinkedIn Search

1. Type the hashtag in search
2. See how many followers it has
3. Review recent posts

Method 2: Follow Hashtags

1. Follow hashtags in your niche
2. See which posts perform well
3. Spot patterns

Method 3: Competitors

1. Analyze successful posts in your niche
2. See which hashtags they use
3. Adapt for your content

Hashtag Strategy by Goal

For Maximum Reach

2 broad + 1-2 medium hashtags

For Specific Niche

1 broad + 3-4 specific hashtags

For Authority

Create and use 1 own hashtag consistently + 3-4 from your niche

Create Your Hashtag

Strong personal brands have their own hashtags:

• #dayinthe lifeofceo
• #pocketmarketing
• #careerminute

To create yours:

1. Keep it short and memorable
2. Don't use special characters
3. Use it in every post
4. Encourage followers to use it

Conclusion

Hashtags are a simple but powerful tool. Use 3-5 per post, mix broad and specific, and be consistent.
