Quick Guide to Using Hashtags on Social Media

October 8, 2017

If your school uses multiple social media networks for promotion and communication, the difference in the use of hashtags may have become apparent. With varying purposes, uses, security features and trends, it can be hard to know how to use hashtags on different networks. We’ve put together a quick guide to take you through hashtag best practices on Twitter, Instagram, Facebook and LinkedIn.


This is where hashtags were born. Used for categorising tweets, hashtags are primarily a tool that users can add to their tweets for the purpose of starting or joining a conversation.

How to use them

Since Twitter hashtags are used for joining discussions rather than getting attention for your tweet, it is best to keep it focused and to use one or a maximum of two per tweet.


Using too many hashtags can dilute your message, and schools should be prepared to continue the conversation if one is created or joined through hashtag use.


Also used for categorisation, their use is functionally the same as on Twitter, however the focus is more around maximising image views than around joining conversations.

How to use them

Add several hashtags but ensure that they are relevant to your post. Decide on one school hashtag to use for every post and to encourage others to use so when sharing school-related social media content.


There is a limit of 30 hashtags per post, and hashtag content is monitored for spam, making it extra important to keep hashtags relevant to their image.


Added with less success than its’ sibling network, Instagram, Facebook’s hashtags serve the same purpose, with less frequent use. The reason for the lesser success is due to the more common, stringent privacy settings of Facebook users. Privacy settings tend to prevent posts from being seen by non-friends, even when a hashtag is used.

How to use them

There’s no harm in adding a hashtag or two to your posts, particularly if it’s a school hashtag.


Don’t expect dramatic results from using hashtags and don’t stress if they’re left off a post.


It’s an on-again, off-again sort of relationship but currently (at the time this article was published), Linkedin does support hashtags on desktop and on mobile. Similarly to on Twitter, Linkedin hashtags are used to categorise content and to create or join conversations.

How to use them

Just like on Twitter, keep it simple with one or a maximum of two hashtags per tweet.


Avoid diluting the message by using too many hashtags.
