GLOSSARY · LINKEDIN MECHANICS
Hashtag
A hashtag on LinkedIn is a word or phrase preceded by the hash sign, such as #b2bmarketing, that turns into a link to a page collecting posts using the same tag. Hashtags were once central to LinkedIn's content discovery and the platform encouraged following them; their importance has declined as the feed moved toward topic detection from post text. Today they are a minor labelling device. A few relevant hashtags do no harm, but a block of ten at the end of a post is a recognisable sign of templated content and adds little.
How it works in practice
Hashtags came to LinkedIn from Twitter and for a period the platform leaned on them: members could follow hashtags, creator mode asked for five topic hashtags under the headline, and hashtag pages showed follower counts. Since then LinkedIn has said that its feed identifies a post's subject from the content itself and from the author's history, which reduces the need for explicit tags. The platform has also removed or de-emphasised several hashtag features over time. For a writer, the practical guidance is to treat hashtags as optional labels. One to three that precisely describe the subject, placed at the end, are reasonable and may help in search.
Hashtags inside sentences interrupt reading. Long lists signal that a post was produced from a template and are one of the features readers associate with low-effort or machine-written content. Hashtags do not substitute for distribution: tagging #leadership does not put a post in front of your buyers, while a relevant comment on a post they are reading does. If you want to be found for a subject, the reliable route is to write about it repeatedly, name it plainly in the text and in your headline, and let the feed and search read the words rather than the tags.
Example
A post on SaaS pricing ends with two tags: #saaspricing and #b2bsaas. The subject is also named in the first line of the post, which is what search and the feed actually read.
Common mistake
Closing every post with a wall of broad hashtags such as #success #growth #motivation #business. It reaches no particular audience and marks the post as formulaic to the readers who matter.
