How to use Hashtags on LinkedIn for Marketing 

Hashtags are coming on as a means to easily find content on LinkedIn. You just enter the hashtagged word or phrase in the search box on LinkedIn and away you go. 

But as usual with LinkedIn there is a secret rule you need to know about. 

LinkedIn recommends you use up to three hashtags, and they even emphasize three as the best number. LinkedIn has also specifically stated that more than three hashtags on a post or article will “hinder it’s distribution.” And when LinkedIn is doing the distribution that means those posts are literally going nowhere. 

And although they don’t say you will be rewarded, when LinkedIn says they recommend you use three, I take that as meaning content with three will be rewarded. 

Now there is something else to take into consideration here. If you have technical content where, say, fifteen different hashtags could be used, there is nothing to say you can’t use them. Just don’t expect any real distribution of that post from LinkedIn. But people can still find the post using a search for hashtags. 

So how should you decide what hashtags to use? Here are the steps I recommend:

  1. Make a list of all the hashtags you think would work
  2. Enter each one in turn in the search bar and search for it. If it is a popular hashtag, LinkedIn will show the number of people following it. 
  3. Go to posts and articles using these hashtags and see what else the authors are using – there may be ones applicable to you that you have not thought of. 
  4. Make a list of popular hashtags and the number of followers each one has. Check the list a month from now, then a month later to see what is rising and falling in popularity. 
  5. If there is a hashtag that you think your prospects would use, then by all means use it even if no one else is. 

Most LinkedIn users and companies using LinkedIn are not organized in their use of hashtags. You can be and can get an advantage over them.
