The LinkedIn hashtag had a topsy-turvy ride on this social media platform.
A few years back they were present but LinkedIn “rolled it back due to poor user response.”
In 2016, they were available on the mobile app only: “Hashtags included in your posts (or others) are now tappable and lead to search results so that you can discover other posts with the same hashtag.”
Then, in 2017, hashtags reappeared on the desktop platform as part of the new user interface. But still, nobody knew what they were supposed to do or how to use them.
By early 2018, reports surfaced of some users being ‘forced’ to insert hashtags into their posts:

LinkedIn confirmed they were running a beta test “to better understand the value of using hashtags in posts to help members discover and join relevant conversations.”
But now, it’s safe to say that LinkedIn hashtags are back and working. So let’s take a look at how you can make the most of them.
LinkedIn hashtags work in a similar way to TikTok, X (Twitter), and Instagram – to categorise the content.
By integrating hashtags into your content, you open the door to reaching a wider audience on LinkedIn. Additionally, the ability to follow hashtags allows your selected posts to surface on your feed, expanding your content's visibility.
In the realm of marketing, hashtags are a game-changer, enhancing the reach of your LinkedIn content to a more diverse audience. Don't be swayed by the chatter about hashtags fading away - they are here to stay and are becoming an essential aspect of social SEO strategies.
As social media platforms transform into search engines, simply throwing in a slew of generic hashtags won't suffice. It's essential to curate a tailored selection of industry-specific hashtags to maximize your reach and engagement. And don't forget to keep track of your successful combinations for future use with Sendible's Content Library.
If you've turned on the Content Creation mode on your LinkedIn Profile, you can share the topics (hashtags) you post about the most. This will make it easier for other LinkedIn members to discover your content and follow you.
For example, when I search for #socialmediamarketing in ‘People’ (rather than the default ‘Content’) I see these results:
LinkedIn allows you to filter hashtags through various categories such as format (People, Jobs, Posts, etc.), Location, Connections, and Current companies.
You'll notice that the searched hashtag in Profile Headline under the talks about section is bolded. While these hashtags aren't as clickable as the ones used in posts, they help you grow your audience and reach.
LinkedIn Pages on the other hand don't have the possibility to add hashtags, but the platform offers you an option to add up to 20 specialities. Company specialities serve as searchable keywords for your Company Page that will help people find your business easier.
There are two sides to using hashtags on LinkedIn:
Finding relevant hashtags to follow, so you can join a conversation.
Adding relevant hashtags to your content, so more people can discover you.
At the top of the homepage, click into the ‘Share an article, photo, video or idea’ field to write your post content:
Add hashtag – using the # symbol – in the body of your post or at the end of the message:

From the homepage, click ‘Write article’ under the status update field. You can include hashtags in the body or at the end of your article, like the post update above.
When you’ve finished writing your article, click ‘Publish’ in the top right corner. You'll now be presented with the Compose Box where you can add more relevant hashtags to better promote your article.
You can also add hashtags when you comment on a post or an article. This is an excellent community management tactic that will help reinforce the searchability of your client's post:
LinkedIn lets you find and follow hashtags on the topics you’re interested in.
Start by entering the topic you’d like to find in the Search bar at the top of the page. For example, when you type #socialmedia you get a list of social media-related hashtags:
Select a hashtag from the list of suggestions – e.g. #socialmediamarketing – to see content related to the hashtag topic in your feed.
Click the ‘Follow’ button at the top of the page to add the hashtag topic to your list:
You can manage the hashtags you follow from your LinkedIn homepage. On the bottom left-hand side is a section where you will find your 'Recent' searches and activity, 'Groups' and ‘Followed Hashtags’:
In the ‘Groups’ and ‘Followed’ sections, LinkedIn displays up to three results with options to see more:
Click ‘Show more’ to expand the list and display more of the groups or hashtags you’re following.
Click ‘Followed Hashtags’ to show the full list of hashtags you’re currently following (here you can unfollow them or see recent posts using said hashtags).
Hashtags on LinkedIn continue to be adopted in 2025, with many having millions of followers. The most popular hashtags on LinkedIn usually consist of one word and are exceptionally broad, making them applicable to many businesses and individuals.
We have curated a list of 30 trending LinkedIn hashtags that are both relevant to marketers and high in follower count (data correct as of January 2025):
However, before you rush off to add any of these hashtags to your posts, remember that with such a high volume of followers and posts trickling in, your posts may go unnoticed by new audiences, and that would defeat the purpose of using hashtags altogether!
Once you choose a hashtag, don't stop there, and do an additional check for similar hashtags. LinkedIn hashtags and their followers vary a lot when it comes to variations, even when they have a similar meaning. For example:
The same goes for hashtags in other spaces:
Finally, just because a hashtag doesn't have a lot of followers yet, it doesn't mean it won't grow in the future. For example, the hashtag#entrepreneur has gained 10x more followers between 2019 and 2021!
So if you find a hashtag that makes sense in a specific niche, you have the chance to become an early adopter.

Now you know how to manage your hashtags on LinkedIn, follow these tips to make the most of every post you publish.
There’s no point using a hashtag if you’re operating in private mode on LinkedIn. Check your profile settings to make sure it’s public to everyone, or else your content (including hashtags) won’t get discovered.
Just because a hashtag is popular, doesn't mean that you should use it. For example, if your brand is promoting financial services on LinkedIn, then using the #fitness hashtag as part of your posts isn't going to attract the right clientele. Keep hashtags relevant to those you're trying to reach.
There’s no limit to how many hashtags you can add to your content. But if you use too many your post will look spammy. LinkedIn best practice suggests that three to five hashtags are plenty.
Some people fall into the trap of cross-posting content from Instagram that includes multiple hashtags. And then their LinkedIn post looks awful.
LinkedIn defaults to lowercase when it displays hashtags; e.g. #socialmediamarketing. But it’s considered a good practice to use capitals at the start of each word, so it’s easier for people to decipher; e.g. #SocialMediaMarketing.
Note: Abbreviated acronym hashtags are not standard on LinkedIn. For example, on Twitter, the common acronym for #SocialMediaMarketing is #SMM, but LinkedIn prefers the full version.
It’s always best to add at least one sentence to your post rather than using hashtags exclusively. Even when you post an image or video, add a short sentence along with your hashtags.
A splattering of hashtags with no context looks lazy and spammy. And LinkedIn’s algorithm stops irrelevant, low-quality, and spammy content from reaching a user’s feed.
You can place hashtags in your message or at the end, but don’t hashtag every word. As Nick Diakanastasis commented:
Write your message first and then see if it makes sense to convert a word into a hashtag, or add a hashtag at the end.
Don’t tag words that aren’t important! Remember to use a hashtag to categorise your post.
Creating a custom hashtag is an excellent way to build your brand across all social platforms, and it makes it easy for followers to identify and connect with you. Rebecca Whitlocke commented:
But there’s another advantage, too. Custom hashtags help you track shares of your LinkedIn posts. As John Espirian explains:
If you want to reference an individual or a company then use the @mention functionality rather than a hashtag:
Don’t test your hashtags like you would spaghetti – throwing a load of hashtags into a post and hoping one of them sticks is not good practice.
Instead, record what hashtags you’ve used on each post and see which ones bring the most engagement.
The best way to do this would be to label your social media content pillars and assigned hashtags with Sendible's Campaigns. This way you'll have an instant overview of the performance of your topic clusters.
Multi-word hashtags can be overlooked in the final proofread for a post, but it's important to make sure you're conveying the correct message. Always double-check spelling to avoid embarrassment, confusion or missing your intended audience.
Hashtags are alive and kicking on LinkedIn.
Use hashtags to make it easier for other users to discover your content, and help you find and connect with other users who share common interests.
Add relevant hashtags to your content as you write posts and add comments, (or use the LinkedIn suggestions if you’re unsure), to make the most of every post you publish for your brand or your clients.
But remember to follow the tips above to ensure your hashtags are a success.
