To hashtag or not to hashtag? That’s the question frustrating social media marketers today.

The short answer: Yes, definitely use hashtags. Hashtags are an essential asset in your digital marketing toolbox.

According to 72% of our LinkedIn community, hashtagging impacts the overall performance of social media content. Forward-thinking brands use them with specific goals and intentional strategies in mind—whether they’re making their product go viral or gaining international press.

Unfortunately, the confusion surrounding hashtags prevents some marketers from using them to their full potential. Which is further complicated by experts who negate the benefits of hashtagging or dismiss them as irrelevant.

In this article, we break down everything you need to know to hashtag with confidence. We explore what hashtags are, how to use them and examples of ways brands are successfully ushering in the new era of hashtagging.

What is hashtagging?

First and foremost, where did it come from? The first hashtag debuted on Twitter in 2007 from a product designer named Chris Messina.

“I designed the hashtag to thwart any one social network from becoming the dominant gatekeeper. Think about it: The hashtag is one of the few superstructures that spans across all social media platforms.

Only hashtags allow similarly-interested folks to find each other—whether they’re on Twitter, Instagram, Pinterest, TikTok, Reddit or elsewhere. It provides a glimpse into what an interoperable, decentralized social web could be like.” — Chris Messina, Inventor of the hashtag

So, what is hashtagging? Let’s break down the basics.

What is a hashtag: The basics

Let’s start with mechanics. Hashtags are words and numbers following the # symbol that categorize and track content on social media. You can add hashtags to social posts, bios and comments on most major platforms, including Instagram, Facebook, TikTok, Twitter, LinkedIn, YouTube and Pinterest.

Note: Hashtags cannot include spaces or punctuation.

What is a hashtag symbol?

Many social media users and marketers immediately recognize the # symbol as a hashtag, but its official name is an octothorpe. The term was first used in 1971 when telecommunications companies introduced the # symbol to the touch-tone dialing keypad.

However, depending on how you use it, the symbol is called many different names. Before its use on social media, it was most widely known as a pound or number sign (example: #2 pencil). Musicians also use the symbol to distinguish a sharp note (example: F#), while copy editors use it to denote adding a space.

In the early days of the internet, chatroom users referred to the symbol as a “hash,” a word borrowed from programmer culture. That’s where Messina was inspired to repurpose it on Twitter. Since then, the term hashtag has dominated modern popular lexicon.

What is the purpose of a hashtag?

Given the sophistication of today’s social media algorithms, it might be difficult to remember the chaotic social feeds of the early 2000s. Users had limited control over what content they saw, and were frustrated by too many uninteresting or irrelevant posts.

Hashtags were invented to help bring order to the social media user experience. Hashtags group together similar conversations to help people find content that matters to them. Once a hashtag is published, it becomes a clickable, searchable link.

For example, when you click on #SummerVibes on TikTok, you can see all videos published on the platform using that hashtag. You can also see the top videos and overall popularity of the hashtag.

What is a hashtag used for?

While organizing feeds was the original purpose of hashtags, their use case has evolved. Now, they empower users to amplify their message. Hashtags have become so powerful they can be the spark that ignites social movements (example: #MeToo, #BlackLivesMatter).

Hashtags aren’t always a force of social change—some viral hashtags are just plain fun. Like #Gentleminions, a TikTok challenge turned cultural phenomenon that led to record-breaking box office numbers for the Minions franchise.

For brands, hashtags can help social marketers reach niche audiences and build community.

According to Messina, “Many more people are interested in finding their community—or growing the one they already run. Hashtags provide a tried and true method across nearly every social media platform.”

Hashtags also help social marketers create viral campaigns, increase brand awareness and reach their business goals.

How to use hashtags

Despite the benefits of hashtags, some marketers are unsure how to use them strategically. For example, if your goal is to reach a specific audience, adding popular hashtags (example: #ForYouPage) to your posts might cast too wide of a net and fail to connect you with the right people.

To perfect the art of hashtagging, you should conduct research, use hashtags thoughtfully and analyze your results.

1. Find the right hashtags #ForYou

Just because a hashtag is popular doesn’t mean it’s the right fit for your brand. Before using a new hashtag, determine your goal (example: increased engagement).

After you have an endgame in mind, start digging into hashtag research. Begin by natively researching existing popular and relevant hashtags across apps. Use these hashtag types for inspiration:

  • Product or service (example: #Pretzels)
  • Industry or community-specific (example: #BookTok)
  • Timely or seasonal (example: #NYE)
  • Location (example: #Dublin)
  • Acronyms (example: #SMMs)

To take it a step further, turn to tools like RiteTag or Sprout Social’s Listening features to identify related keywords and hashtags already associated with your brand.

You might discover creating your own branded hashtag is the best way to reach your goals. Branded hashtags increase visibility, clicks, mentions and overall reach.

For most brands, using the right mix of popular, niche and brand-specific hashtags is the sweet spot for discoverability and engagement. Above all, it’s most important to identify hashtags that will help your brand stand out from your competitors and contribute toward your unique goals.

2. Use #relevant hashtags in your social content

Once you identify which hashtags you’re going to use, it’s time to start adding them to your content. With hashtags, the general rule of thumb is less is more. Avoid stuffing your posts full of hashtags. Not only could this deter people from reading your message, it could also lead the social platform to categorize your posts as spam.

In general, stick to a few hashtags that are relevant to or describe your post. To determine exactly how many hashtags you should use, follow the best practices of each social platform. Keep reading to learn more about platform-specific best practices in the next section of this article.

When you write your copy, customize your hashtag placement according to each platform’s guidelines. Keep in mind that hashtags are hyperlinks. Adding them to the bottom of your captions, descriptions or posts works best to prevent people from clicking away.

3. Analyze and report on your hashtags’ #progress

Tracking your hashtags is the most critical thing you can do to make sure they’re impacting your social performance. Monitor key metrics on a regular basis, including:

  • Popularity: How many people are using the hashtag?
  • Reach: How many people see the hashtag you’re using?
  • Interactions: How many people engage (like, share or comment) with posts that include the hashtag?
  • Users: Who is seeing the hashtag?

You can find some of this data in the native apps. If you want to automatically generate and visualize it in one place, use a tool like Sprout Social.

In Sprout, there are multiple ways to track the performance of your hashtags. For example, you can use Listening to find out how frequently people are talking about your topic, what related terms they’re using and the sentiment around the topic.

Use data to determine which hashtags work well and which ones don’t. Continue to experiment and test new tags to avoid using the same hashtags on every post—this could register as spam. Instead, keep your best performing hashtags on rotation and try out new ones often.

Using hashtags on different social networks

When using hashtags across your social presence, don’t take a one-size-fits-all approach. Tailor hashtagging to suit each platform. Here are up-to-date hashtag best practices you can follow to supercharge your content and grow your reach.

How to use hashtags on Instagram

According to Instagram’s Creator Community, IG users should “think of hashtags as a tool that provides context about your post and supports delivering content to people who are interested in a particular topic.”

The Creator Community also lays out these guidelines:

  • Use hashtags in your posts, comments and Stories
  • Only use hashtags relevant to your community and brand

How to use hashtags on Facebook

  • Only use 1-2 hashtags
  • Use hashtags in your posts, comments and Stories
  • Use timely hashtags since many users turn to Facebook for news and events

LinkedIn is also a great place to roll out your branded hashtags, and encourage your team members to use them too.

When using hashtags on LinkedIn, consider these best practices:

  • Only use 3-5 hashtags per video
  • Use 1-2 hashtags in your title and the rest in your description

How to use hashtags on Pinterest

Pinterest helps create a personalized experience by sorting all Pins into categories. People look for “pin-spiration” for everything from holiday decor to muscle cars, so adding niche hashtags to your posts make it easier to reach the right audience.

"Get a taste of these clever wraps" over an image of a veggie wrap, "Astrology nails for every zodiac" over an image of color nail art designs inspired by astrology, "Your phone's full screen potential is here" over an image of lock-screen options, "Celebrating Bastille Day" over an image of people eating a charcuterie board with a lot of french bread, "These luxe pet styles have purr-sonality" over whimsical images of cats and dogs dressed in human outfits and "Queue up your summer playlist" over an image of a person tuning an old-fashioned radio.

Use these hashtag tips to help your Pins be seen by your intended audience:

  • There isn’t official Pinterest data to support the number of hashtags you should use. Use your own discretion and, remember, less is more.
  • Use timely hashtags since users are often on Pinterest to gain seasonal ideas
  • Make sure your hashtags are relevant to your Pin
