How To Use A Hashtag

What Is a Hashtag?

A hashtag is used primarily on social network sites like Twitter, Instagram, Facebook, Pinterest, and LinkedIn. Most of the top social media sites use them in one way or another.

Using a hashtag is a way to mark your message as belonging to a topic or theme. Other people can then search for this hashtag to find messages about something that interests them. A hashtag is often hyperlinked, so you can click it and be taken directly to those search results.

A hashtag is formatted by a # sign followed by text. The # symbol itself is sometimes called a hashtag, but the two aren’t the same. The # symbol is actually called a number sign, pound sign, octothorpe, or hash. Its usage varies by country, but it is often used alongside ordinal numbers or as a symbol for the pound as a unit of weight.

As such, the term hashtag primarily has purpose online on social networks. Here’s an example of a hashtag being used on Twitter:

How to Use a Hashtag

Anyone has the power to create a new hashtag. And they’re used by individuals and businesses alike. Simply type the # sign, followed by a word or phrase, and your hashtag is done. If someone else has used the same hashtag previously, your post will appear alongside those when people search for that hashtag.

There are some rules you should follow to ensure your hashtag displays and functions correctly:

A hashtag should always begin with the # symbol. If it’s not the first thing in your message, ensure there’s a space beforehand. For example, “I love tech #siitgo” is good, while “I love tech#siitgo” is not.

Don’t use punctuation, special characters or spaces in a hashtag because it won’t work. For example, “I love tech #make use of” would only hashtag the word “make”.

You can use capital letters in a hashtag, but this is only for readability. For example, both #siitgo and #Siitgo are the same hashtag.

When to Use a Hashtag

You can use a hashtag whenever you want. There’s nothing to stop you type a # sign followed by some text and you’ve created a hashtag.

Using Hashtags for Events

Generally, the best use of a hashtag is when you want to create or join a discussion around a specific topic. Let’s say your local town of Springfield is having a fun run. You could put a message on social media like:

Best of luck to my friend Homer today! As long as you get across the finish line, that’s all that matters. #SpringfieldFunRun

Other people could then use the same #SpringfieldFunRun hashtag. Then, when others click that hashtag or search for it, they will see all the messages related to that event.

Using Hashtags for Businesses

Equally, hashtags can be used on a global level by businesses. Here’s an example from the Star Wars Twitter account, which used multiple hashtags to promote The Mandalorian on Disney Plus:

You might also notice hashtags appear offline in all sorts of places, like movie trailers, billboards, and TV commercials. That’s because these businesses want you to go online, discuss their product or service, and use the hashtag to create a buzz.

Using Hashtags for Comedy

Hashtags can also be used ironically or sarcastically. This is often when the user isn’t interested in grouping their message to a discussion, but instead trying to be funny. For example:

Just ate a huge cake all to myself. I feel great! #DietStartsNow

This comedic application of the hashtag also applies when it’s spoken out loud because, obviously, the group and search functionality of a hashtag isn’t possible to achieve in speech.

Using Hashtags for Causes

Some hashtags have transcended their online origin. This can be seen in the phrase “Je Suis Charlie”, meaning “I am Charlie”, which was a slogan created to show solidarity after the shootings at the Charlie Hebdo magazine in 2015.

The statement began as #jesuischarlie on Twitter before being used in music, cartoons, and newspapers. The hashtag then morphed into the more general #jesuis, which was used globally as a sign of alignment to different causes.
