Hashtags on LinkedIn still matter because they help the algorithm understand your topic and help the right people discover your posts. Used well, they improve topical consistency without making your writing look spammy.

1. Use 3-5 highly relevant hashtags per post

On LinkedIn, more is not better - aim for 3-5 hashtags that tightly match your post topic. This keeps your post readable and reduces the risk of looking like engagement bait. Start with 1-2 core hashtags you want to be known for, then add 1-3 supporting hashtags that match the specific angle of the post.

2. Mix broad, niche, and audience-specific hashtags

Combine one broad hashtag (example: #marketing), one niche hashtag (example: #demandgen), and one audience-specific hashtag (example: #saasmarketing) to balance reach and relevance. Broad tags can bring volume, but niche tags often bring higher-intent readers who actually comment and follow. This mix helps you avoid getting lost in huge feeds while still expanding beyond your existing network.

3. Research hashtags using LinkedIn search and hashtag pages

Type # plus a keyword in the LinkedIn search bar to find existing hashtags and open their pages to see how active they are. Follow the relevant hashtag pages so they appear in your feed and you can spot what formats and topics perform well. When writing a post, use LinkedIn's hashtag autocomplete suggestions to pick the exact tag variant people already use (small spelling differences can split the audience).

4. Create a small set of repeatable hashtag bundles

Build 3-5 reusable bundles (each 3-5 hashtags) for your main content pillars, like thought leadership, how-to, hiring, or product. Save them in a note, text expander, or your scheduler so you can apply them consistently without rethinking every time. Consistency helps LinkedIn associate your profile with specific topics and makes your analytics easier to compare.

5. Place hashtags for readability and scanning

Put hashtags at the end of the post or on a separate last line so they do not interrupt the story or the hook. If you use a hashtag in the body, keep it to one and only when it naturally fits the sentence. Clean formatting improves dwell time and makes it more likely people will finish the post and engage.

6. Add a branded hashtag for campaigns and attribution

Use a unique branded hashtag (example: your newsletter name or event name) when you run a recurring series, webinar, or content challenge. This makes it easier for people to click the hashtag and find the full series in one place. Keep it short, consistent, and specific so it does not get confused with generic terms.

7. Measure results and iterate with real analytics tools

Track which hashtag bundles correlate with higher impressions, comments, and profile visits by logging what you used and reviewing post analytics trends weekly. Tools like Shield (LinkedIn analytics) help you monitor performance over time and export data so you can compare similar posts that used different hashtag sets. If you use a publishing tool like Taplio, test its hashtag suggestions, then A-B test two bundles across similar posts to learn what brings the right audience, not just more views.

Conclusion: The best LinkedIn hashtag strategy is consistent, specific, and measured. Start with tight relevance, then refine your bundles based on real performance data.
