LinkedIn has evolved into the world's largest professional network, with over 1 billion members using the platform to connect, share insights, and build their personal brands. But with millions of posts published daily, how do you ensure your content reaches the right audience? The answer lies in understanding how to use hashtags on LinkedIn strategically.
Hashtags remain a powerful tool for content categorization and discoverability, though their role has shifted significantly. Unlike the early days when hashtags could drive viral reach, today's LinkedIn algorithm prioritizes engagement signals while still using hashtags as important content labels. This guide walks you through everything you need to know about using hashtags effectively on LinkedIn in 2025.
What Are LinkedIn Hashtags?
LinkedIn hashtags are keywords or phrases preceded by the # symbol that categorize your content and help it become discoverable to professionals interested in those topics. When you click on a hashtag or search for one, LinkedIn displays all public posts tagged with that keyword. According to Sprout Social's comprehensive analysis, hashtags function as primary content categorization tools that help the platform's algorithm understand and distribute your posts to relevant audiences.
How Hashtags Work Technically
From a technical perspective, LinkedIn processes hashtags as structured metadata. When you publish a post with hashtags, LinkedIn's natural language processing (NLP) systems parse these tags as topic classifiers. The platform then indexes your content under each hashtag, making it eligible to appear in that hashtag's feed and in search results for related queries. As Oktopost explains in their technical breakdown, this NLP-driven approach means hashtags work alongside LinkedIn's keyword detection system rather than as standalone discovery tools.
Why Hashtags Still Matter in 2025
Despite changes to LinkedIn's algorithm, hashtags continue to serve several important purposes:
- Content categorization: Helps LinkedIn understand what your post is about
- Search optimization: Hashtags remain clickable and searchable in LinkedIn's search bar
- Niche discoverability: Specific hashtags help your content appear in searches for specialized topics
- Community connection: Following relevant hashtags keeps you connected to industry conversations
When combined with a broader social media marketing strategy, effective hashtag usage becomes an integral part of professional content distribution. For optimizing your entire company presence, learn how to optimize your LinkedIn company page to maximize visibility across all LinkedIn touchpoints.
How To Add Hashtags On LinkedIn
Adding Hashtags to LinkedIn Posts
The most common place to use hashtags is in your regular posts. Here's how to add them:
- Click "Start a post" at the top of your LinkedIn homepage
- Write your content as usual
- When you want to add a hashtag, simply type the # symbol followed by your keyword
- LinkedIn will suggest relevant hashtags as you type, but you can also create custom ones
- Continue adding hashtags naturally throughout or at the end of your post
As noted by Hootsuite's platform guide, the platform's autocomplete feature makes it easy to discover popular hashtags while still allowing you to create unique tags for specific campaigns or topics.
Adding Hashtags to LinkedIn Comments
Hashtags in comments work the same way as in posts:
- Navigate to the post you want to comment on
- Click in the comment field
- Type your comment, including hashtags with the # symbol
- Post your comment
Adding Hashtags to LinkedIn Articles
For long-form content, LinkedIn articles also support hashtags:
- Click "Write article" from your homepage
- Write your article content
- Hashtags can be embedded within the text or added at the end
- Publish your article
Adding Hashtags to Your LinkedIn Business Page
Business pages have a dedicated field for hashtags called "Specialisms":
- Navigate to your LinkedIn business page
- Click "Edit page" and then "Details"
- Scroll to the bottom to find "Specialisms"
- Add up to 20 relevant keywords (without the # symbol) that describe your business
This business page optimization complements your content marketing efforts by improving discoverability across LinkedIn's platform. According to Sprout Social's guidance, properly configured specialisms help business pages appear in more relevant searches and recommended content feeds.
LinkedIn Hashtag Best Practices
Optimal Number of Hashtags
LinkedIn recommends using 3 to 5 hashtags per post. This balance helps categorize your content effectively without overwhelming your audience or appearing spammy. Oktopost's research confirms that posts within this range consistently outperform those with either too few or excessive hashtags across B2B professional audiences.
Where To Place Hashtags
Placement matters for readability and effectiveness:
- End of post: Keep your message clean and add hashtags at the bottom
- Embedded in text: Naturally incorporate hashtags within sentences for a more organic feel
- First comment: Some users prefer keeping the main post clean by adding hashtags in the first comment
As Sprout Social's placement analysis demonstrates, different placements work better for different content types and audience preferences.
Mix Broad and Niche Hashtags
The most effective hashtag strategy combines both types:
- Broad hashtags (like #Marketing or #Leadership) increase visibility but face more competition
- Niche hashtags (like #B2BLeadGeneration or #SaaSMarketing) target specific audiences with higher relevance
This strategic mixing mirrors best practices in search engine optimization, where targeting both head terms and long-tail keywords drives the best results. Understanding your social media target audience helps you identify which niche hashtags will resonate most with your ideal professional community.
Accessibility Matters
Make your hashtags readable by capitalizing each word:
- Use #SocialMediaMarketing instead of #socialmediamarketing
- This helps screen readers interpret hashtags correctly
- Improves readability for all users
Following Hootsuite's accessibility recommendations ensures your content reaches professionals with disabilities while maintaining a polished, professional appearance.
How To Find Relevant LinkedIn Hashtags
Using LinkedIn's Search Bar
- Type a keyword into LinkedIn's search bar at the top
- Select the "Posts" tab
- Review which hashtags appear in high-performing content
Competitor Analysis
Study what hashtags competitors and industry leaders use:
- Identify recurring hashtags in top-performing posts

Third-Party Hashtag Tools
Several tools can help discover relevant hashtags:
- LinkedIn's native suggestions: Appear as you type # in posts
- Social listening platforms: Monitor trending topics in your industry
- Analytics tools: Identify which hashtags drive engagement on your content
As Hootsuite's discovery guide outlines, combining these methods provides the most comprehensive hashtag research for your professional content strategy.
Common LinkedIn Hashtag Mistakes To Avoid
Overusing Hashtags
More isn't better. Using too many hashtags can:
- Appear spammy to your audience
- Dilute your content's focus
- Potentially trigger LinkedIn's spam filters
Using Irrelevant Hashtags
Hashtags must relate to your content. Irrelevant tagging:
- Hurts your credibility
- Frustrates your audience
- May negatively impact your reach
Ignoring Hashtag Performance
Not tracking which hashtags work means missing optimization opportunities:
- Review your post analytics regularly
- Identify patterns in high-performing hashtags
- Adjust your strategy based on data
Focusing Only on Popular Hashtags
High follower counts don't always mean better results:
- Popular hashtags have more competition
- Niche hashtags often drive more relevant engagement
- Test different combinations to find what works
These mistakes can undermine even the best content strategy, making hashtag optimization essential for professional content success.
