Hashtags on LinkedIn are quite new – they were introduced in 2018. LinkedIn Hashtags work differently than on Instagram and Twitter – you can use them in your articles (up to 5) and ‘updates’ (posts). It is not possible to add or edit hashtags after posting.
Go to ‘Hashtags trending in your network’ to discover the relevant hashtags for your audience – choose ‘My Network’ and then ‘See all’ under the ‘Hashtag’ section.
Do not use more than 5 hashtags in your posts.
Alternate between the popular or trending hashtags and niche ‘long-tailed’ hashtags.
