The term "hashtag" is made up of the English words "hash" and "tag". Accordingly, a hashtag is a keyword marked with a hash. Hashtags are used to make posts with specific content or topics easier to find on social networks. By labeling their posts with a hashtag, users assign them to a thematic category.

On Facebook, Instagram, TikTok and X (formerly Twitter), this integrates the post into the keyword search. This means that other users can find the post by searching for the corresponding hashtag.

Hashtags in social networks

In the world of social networks, hashtags play a central role in structuring content and encouraging interaction between users. These keywords, marked with a double cross sign (#), make it possible to quickly find and categorize posts on specific topics or events. By including a hashtag in a post, it automatically becomes part of a larger, thematically related conversation system. This allows users to share posts beyond their own followers and reach a wider audience.

Function and use

Hashtags make it possible to bundle posts on specific topics and make them easy to find. They play a central role in the dissemination of information, the formation of opinions and the organization of social movements. For example, hashtags can be used to draw attention to current events, campaigns or trends. They also serve as a means for companies to present their products or services in a thematic context and engage with a targeted community.

Examples

  • #ootd ("Outfit of the Day"): 437 million Instagram posts
  • #tbt ("Throwback Thursday"): 586 million Instagram posts
  • #love: 2.1 billion Instagram posts

Guidelines and best practices

Although the use of hashtags seems relatively straightforward, there are some unwritten rules and best practices that help maximize their effectiveness. These include limiting yourself to a manageable number of relevant hashtags to increase the visibility and relevance of the post. In addition, hashtags should be precise, clear and as short as possible. The use of overly general hashtags can lead to posts being lost in the masses and not reaching the desired target group. The following rules should also be observed:

  • Hashtags must contain letters
  • Hashtags may also contain numbers and emojis
  • Hashtags cannot contain spaces or special characters, underscores work
  • Hashtags can be as long as you like, but for better readability no more than fourteen characters are recommended

Benefits for online marketing

Hashtags are invaluable for online marketing as they help companies increase their visibility on social media and communicate with their desired target audience in a targeted manner. By using specific, relevant hashtags, brands can effectively categorize their content, making it easier to be found by users interested in certain topics or products. Hashtags also allow campaigns to be organized and tracked by creating a unique tag that is used specifically for a promotion or event. This makes it easier to analyze reach and engagement and provides valuable insights into the target group's interactions with the brand. Hashtags also encourage community participation and interaction by stimulating discussion and encouraging users to share their own content under the campaign hashtag. This can significantly increase brand awareness and encourage the viral spread of content. Overall, hashtags are a simple yet powerful tool in online marketing that helps brands expand their reach and build a deeper connection with their audience.

Criticism and challenges

Despite their usefulness, hashtags are also subject to criticism. Problems such as hashtag spamming, where irrelevant tags are misused for advertising purposes, or the use of hashtags in controversial or harmful contexts pose challenges. In addition, the flood of information generated by popular hashtags can impair the visibility of individual posts and reduce the quality of discussions.

Conclusion

Hashtags are a key element in the digital world, increasing the visibility of content and encouraging interaction on social networks. Despite certain challenges such as spamming and information overload, they offer companies and individuals great opportunities for targeted communication and branding. Using hashtags wisely and responsibly can make a significant contribution to increasing online presence and the success of marketing strategies.
