What is a Hashtag? And What Do You Do With Hashtags?

Published: Aug 11, 2013 Last Updated: Jul 14, 2021 by Anita Campbell In Social Media 97, Small Business Trends

A hashtag or this symbol “#” as it is more commonly known has become an integral part of social media. If you have never used it and you’ve asked yourself what is a hashtag and what does hashtag means, here is a great primer to get you up and running.

This article was in part inspired by someone who commented here on Small Business Trends by saying, “I’m still not sure how hashtags are being used, or how to use them, or when to use them, or what the significance is in using them… totally confused ….” We hear you, Dr. C — hashtags are baffling to those who do not spend a lot of time online or who are new to social media.

So today we’re going to tackle the question “What is a hashtag?” in plain language. We will also address the business significance of hashtags, and how hashtags can help you in marketing.

What is a Hashtag?

A hashtag looks something like this: #MarathonBombings or #SmallBizQuote. Hashtags are used mostly on social media sites. They rocketed to fame on Twitter. But now you can use hashtags on other social platforms, such as Instagram, Facebook, Pinterest, and Google+. Anyone sharing content on a relevant topic can add the hashtag label to their message. Others searching for that topic can search for that label to find other messages on that same social media platform.

For example, during the horrific Boston Marathon bombings in the spring of 2013, several hashtags were used. They proved invaluable for providing and following up-to-the-minute news about the bombings. In fact, several big news stories in recent years have been amplified and added to citizen reports and amateur videos, and photographs.

Hashtags, however, are not limited to big news stories. Small business marketers have also cracked the code and figured out inventive ways to use hashtags. We’ll discuss the marketing uses of hashtags more below.

But first, let’s talk about some nuts and bolts to understand hashtags better.

How To Hashtag

Hashtags are simple things. There are just a few technical requirements to know: No Spaces Allowed A hashtag can be a single word, an abbreviation, an invented combination of letters and numbers, or a phrase. If it is a phrase, there can be no spaces between words. All letters and numbers must run together without spaces in a hashtag. You can’t have punctuation or symbols in your hashtag (other than the # symbol at the beginning). Numbers are OK, but you must also have at least one letter with the numbers — hashtags cannot consist entirely of numbers. Start With the # Symbol But in other places, such as the United Kingdom and Ireland, that # symbol is called a hash sign. So you see, that’s how these labels came to be called “hashtags.” In essence, a hashtag is a label that consists of a word or phrase tag with a hash symbol in front of it. Create Your Own Hashtag Anyone can create a hashtag. I’ve created numerous hashtags over the years. You could create one of your own or several if you wish. Usually, you add it to the end of messages. But you could add it anywhere in the message that makes sense, as long as it’s readable. You are not required to register a hashtag anywhere. There are some hashtag directories around, but they are unofficial, outdated, and usually not worth the trouble.

Make Hashtags Unique If you think you’ve invented a hashtag that’s completely new, do a search first on the social platform you intend to use it on. We find that about 25% of the time, the hashtag we want to use is already being used for some other purpose. Now, there’s no hashtag police. So technically, there’s nothing stopping you from using a hashtag already in use. But doing so will cause confusion, or worse, be seen as an attempt to hijack a discussion just to gain attention. If the hashtag you want is in use, it’s best to go back to the drawing board. Don’t forget to check usernames, too. Make sure your intended hashtag is not the same as an existing username on a social network. Here again, it may cause confusion to use a hashtag such as #DellSMB if there is a user @DellSMB. Besides, the user probably would interpret it as an attempt to hijack their brand name. You could find yourself on the receiving end of a cease-and-desist letter, or with the social platform taking action for violating someone’s trademarked name if the issue is taken to extremes. One exception to the uniqueness concept: some people use general topics as hashtags, such as #Marketing or #Sales. We discuss the use of general topics below — in essence, no one “owns” a general topic hashtag.

Make Hashtags Easy to Remember and Understand

Keep hashtags as short as possible. That’s especially important for Twitter where you have a limited character count. It’s best if a hashtag is an understandable word, phrase, or abbreviation. Hashtags that are long, hard to pronounce, or hard to remember, will be hard for people to use, too. You can’t go wrong with something short and easy to remember. On Google+, you get an added benefit: Google’s technology will automatically assign a hashtag to your content, without you doing anything. You can tell it not to add the hashtag if you prefer, so you can manually add your own hashtags. How to Use a Hashtag That Already Exists Rather than creating your own hashtag, sometimes you want to enter a discussion around a topic where a hashtag already exists. You would simply add that hashtag somewhere (usually at the end) of your Twitter tweet or other social media updates. By doing so, you are sharing your content related to that same topic. By adding the hashtag to your content, you are saying “Hey, I want to chime in on this discussion.” Others interested in that topic will see your content.

When Not to Use Hashtag

Avoid hashtag pollution. This is using multiple hashtags in a single message. Any more than two hashtags in a message makes it difficult to read.

It’s considered bad etiquette to add a hashtag to an unrelated message just to get attention. Always make sure your content is relevant to the hashtag you use. Otherwise, people may report you for being a spammer, or respond testily.

How to Use Hashtags for Your Small Business

There are as many ways to use hashtags for your business as creative people can think up. Here are 7 ways small businesses use hashtags, either their own, or hashtags started by others — and most can be done on a very small budget or for free: 1. Market your business by holding a contest You can hold a contest and use a hashtag to get people to enter your contest and gain followers on your Twitter account, too. Be careful on Facebook, as Facebook has certain strict rules about running contests. But it’s easy on Twitter. Here’s an example:

2. Network with people using #FollowFriday The #FollowFriday (or #FF for short) hashtag is a simple way to network with others. On Fridays, you give a shout out to people whose tweets you find helpful. This is a key way that followers get our attention, and we’re likely to follow them back.

3. Use a hashtag to hold a Twitter chat Text chats are held on Twitter. Since Twitter is just one big open platform, you have to have some way of designating who is participating in the chat. Otherwise, you have no way of knowing whether a tweet is responding to something someone else said in the chat, or not. That’s where a hashtagis useful. Assign a unique hashtag, everyone uses it, and voila — you are hosting a discussion, albeit a text discussion. Don’t want to organize your own chat? Then participate in a standing chat. Try #SmallBizChat on Wednesdays, from 8 to 9 pm Eastern time,with host Melinda Emerson. Read: How to participate in a Twitter chat.

4. Attend a conference and connect with other attendees Most conferences and business events these days have a dedicated hashtag assigned for the event. An easy way to find out who else is there and connect with them in person is to check the Twitter stream for the hashtag. See who tweets, and then send a direct message to that person, to set up a time to connect.

5. Find and share business content using “general topic” hashtags You can find valuable business content through Twitter, by checking hashtags for general topics such as #Marketing or #SmallBiz. Want your content to spread further? Use such hashtags when sharing your own content and maximize who can see your content. You can do something similar on other social platforms, such as Pinterest. Let’s say you sell food products, such as your own line of BBQ sauces. You could use the #BBQ hashtag on Pinterest to share photos of recipes using your product and to connect with others who like barbeque.

6. Use hashtags for Awards nominations

For the Small Business Influencer Awards, we use the hashtag #SMBinfluencer. It’s a way to develop energy and excitement around the Awards, and for us as the Award organizers to track discussion around it. Nominees use it to see the discussion other nominees engage in and share with their communities.

7. Use for competitive intelligence
