Every brand’s digital marketing plan includes social media. Due to continuous information sharing, businesses often need help to stand out and reach their target audience. This is where hashtags help. Hashtags have transformed content organization and discovery on Instagram, Twitter, Facebook, LinkedIn, and TikTok. This comprehensive guide will discuss hashtags, their function in social media marketing, and how to reach more people and engage with your audience.
What Are Hashtags?
Hashtags, denoted by the symbol #, are keywords or phrases used to categorize and organize content on social media platforms. They enable users to find and explore relevant content by clicking on or searching for specific hashtags. For example, if you are a shoe retailer, you can use hashtags like #skateshoes or #formalshoes to tag an image of those shoes. When users click these hashtags, they are directed to a collection of related content.
The Benefits of Using Hashtags
Using hashtags in your social media posts offers several benefits for users and brands. For users, hashtags enhance the overall browsing experience by allowing them to discover new content and connect with like-minded individuals. On the other hand, brands can leverage hashtags to:

- Expand Reach: Hashtags increase the visibility of your content by making it discoverable to a broader audience. Tweets with hashtags, for example, receive twice the engagement compared to those without.
- Organize Content: Hashtags are a convenient way to categorize and organize social media content. They enable prospective customers and users to find what they seek and navigate your posts more efficiently.
- Improve Engagement: Utilizing relevant hashtags can significantly boost engagement with your audience. Research shows that incorporating hashtags into your social media strategy can result in 21% more employment.
- Convey Brand Values: Hashtags can concisely signal your business’s beliefs and values. By incorporating hashtags like #BlackLivesMatter or #StopAsianHate, brands like Nike can communicate their stance on critical social issues.
Choosing the Right Hashtags for Your Brand
Choosing the right hashtags for your business is essential so your content gets to the right people. Here are some excellent tips that will help you find and pick the best hashtags:
Analyze Competitors
One way to discover good hashtags is by observing what other businesses in your industry use. Analyze the hashtags used by your competitors and identify which generate significant engagement. Tools like Semrush Social Tracker can provide valuable insights into your competitors’ best-performing hashtags, saving you time and effort in the research process.
Utilize Auto-Fill Feature
Many social media platforms offer an auto-fill hashtag feature that generates related hashtags as you type. Take advantage of this feature by typing in a keyword or phrase related to your industry, product, or target audience. The platform will suggest relevant hashtags that you can use in your posts.
Leverage Social Tracker
Semrush Social Tracker may also recommend business hashtags. You may discover which hashtags get people to interact with your posts by watching your competitors on social media and adapting your strategy.
Stick to Industry Relevance
When selecting hashtags, it’s essential to ensure they are relevant to your industry, product, and target audience. Using irrelevant hashtags may need to be clarified or alienate your audience. Avoid the temptation to spam your posts with popular but unrelated hashtags, as this can harm your reach and reputation.
