Hashtags have been around since 2007 and the platform where they first appeared was Twitter.

Chris Messina, the “inventor” of the hashtag, had a revolutionary idea that wasn’t well received back then. He suggested that putting the pound sign in front of words or phrases in tweets could cluster topics and make them easily searchable.

Messina’s persistence paid off. Today, hashtags are popular on all major social media platforms — Twitter, Instagram, Facebook, TikTok, YouTube and even LinkedIn.

What is a Hashtag?

Frequently asked questions about hashtags in social media include the basics like “what is a hashtag” or “what does a hashtag mean?”

A hashtag is a word or phrase preceded by a hash symbol (#) on social media platforms, used to categorize content and make it easily discoverable.

When someone clicks on a hashtag, they'll see a feed of all public posts that include the same hashtag. Private account posts that contain hashtags are not publicly visible — they are only available to private account followers or connections.

What Is the Purpose of Hashtags in Social Media?

Hashtags are designed to improve the user experience on social networks.

Today social media algorithms are advanced and sophisticated.

Still, in the early 2000s, users had very little control over the content they saw on their feeds, which led to frustration and dissatisfaction.

The hashtags changed the way search on social media functions, making content more discoverable and allowing users to easily find and follow conversations, topics, events and trends related to that specific hashtag.

When someone clicks on a hashtag, they are shown a feed of all the public posts on that specific social media platform that have used that hashtag. This allows users to see a curated selection of content related to a particular topic, making it easier for them to engage with relevant information.

For example, when someone clicks on the hashtag #SocialMediaMarketing on Twitter, they will see all public posts that use this hashtag.

How To Use Hashtags in Social Media

Hashtags can improve your social media marketing strategy and make it more efficient, but only if you follow the best practices while using them:

1. Learn the Hashtag Basics

Follow these rules when adding hashtags to your social media posts:

  • Always put the hash (#) sign in front of the word. Don’t use spaces if your hashtag has more than one word. You cannot use punctuation signs in hashtags.
  • Don't overuse them. A #sentence #written #this #way is #illegible and #difficult to #understand. Use the hashtag 1 to 3 times per post, depending on the social network platform.
  • Keep it as simple as possible. If it contains more than one word, capitalize each word to make the hashtag more readable #UseHashtagsCorrectly.
  • Use hashtags the audience is searching for. Unusual hashtags with low search volume won’t attract users to your post.
  • Use specific terms instead broad ones. Broad terms have an enormous reach and your post will sink in and go unnoticeably.

2. Choose the Right Hashtags for Your Niche

Using popular hashtags if your posts are not relevant in content is not recommendable. Instead, determine the goal you want to achieve and start looking for the most effective hashtags for your niche. Hashtag research tools such as Keyhole, Hashtagify or Sprout Social can help you identify keywords and hashtags relevant to your brand.

Your hashtags can be product-related (for example, #Smartphone), seasonal (#Thanksgiving), social cause (#MeToo), location-oriented (#NY) or acronyms (#SMM).

Branded hashtags are a great way to boost reach, discoverability and engagement. It consists of your company's name — for example, ours is #DesignRush.

Another interesting type is influencer hashtags which influencers create to help their followers find and engage with the content they create. These hashtags are usually short and catchy and often include the influencer's name, brand or signature catchphrase.

3. Use Hashtags in Your Content

Once you've chosen the hashtags, start adding them to your content, but do it sparingly.

The rule of less is more is especially applicable here. If you overuse hashtags, your posts may appear difficult to understand and cluttered; therefore, social media platforms may consider them spam. On the other hand, using a few hashtags relevant to your content will add value and boost your brand's visibility, contributing to the success of your SMM strategy.

4. Track Your Hashtag Strategy Progress

Monitoring the performance of your hashtags is the best way to find out if and to what extent they are contributing to the success of your social media campaigns.

Each social network has its own analytics, but you can get more detailed reports using the hashtag research tools mentioned above.

You should pay attention to the metrics of popularity, reach, interactions and users. They will help you decide which hashtags are performing well and which you should replace.
