TikTok has rapidly evolved into a dominant force in social media, and at the heart of its dynamic ecosystem lies the humble hashtag. More than just a symbol, hashtags on TikTok serve as vital pathways for content discovery, audience connection, and ultimately, platform success. Understanding their function and employing them strategically is no longer optional; it is a fundamental requirement for anyone seeking to amplify their presence and impact on this vibrant platform.
Hashtags on TikTok are essentially digital labels applied to video content, denoted by the “#” symbol followed by a word or phrase.1 These labels play a crucial role in categorizing the vast ocean of videos uploaded daily, making it easier for users to find content that aligns with their interests.1 The mechanics are similar to those on other social media platforms like Instagram and Twitter, where hashtags connect users with relevant discussions and topics.1 By adding a hashtag to a video’s description, creators ensure that their content becomes discoverable when someone searches for that specific tag.1 This allows users to participate in trending conversations or explore niche interests simply by searching for the corresponding hashtag.1 TikTok even curates “featured pages” for particularly popular topics, acting as specialized “For You” feeds dedicated to those specific interests.2 This suggests that users familiar with the concept of hashtags from other platforms will find the functionality on TikTok largely intuitive. However, the platform’s emphasis on short-form video and its unique algorithm give TikTok hashtags their own distinct flavor and importance. The existence of these specialized feeds underscores the potential for even highly specific content to find a dedicated audience through the appropriate use of niche hashtags.
The TikTok algorithm, the engine that drives content distribution on the platform, relies significantly on hashtags to decipher the nature of each video. These tags act as crucial signals, informing the algorithm about the video’s content and helping it to determine which users might find it engaging.6 Alongside elements like the video’s audio, the text in the caption, and how users interact with the content, hashtags contribute to the algorithm’s understanding. For creators aiming to expand their reach and connect with broader audiences, the strategic use of relevant hashtags is therefore essential.3 By including these descriptive keywords, creators essentially communicate to the TikTok system what their content is about, making it more likely to appear in the feeds of users who are actively searching for or interested in those topics.4 This highlights the fundamental role hashtags play in ensuring that content reaches its intended audience. The fact that the algorithm considers hashtags as a primary indicator of content theme underscores their importance in any content optimization strategy for TikTok.
Employing hashtags strategically offers a multitude of benefits for TikTok creators. Firstly, using relevant hashtags can attract individuals who are already showing an interest in the specific topic of the video.1 This improved visibility can then translate into higher engagement rates, with more users likely to like, comment on, and share the content.1 Furthermore, hashtags enable creators to connect with a targeted audience that shares a specific interest in their content niche.2 For videos that resonate within a particular hashtag community, the potential for virality significantly increases, allowing the content to reach a vast and diverse audience.2 By strategically using both popular and relevant hashtags, creators can also attract new followers who are drawn to their specific content style and themes.2 This strategic approach allows creators to extend their reach beyond their existing follower base and tap into entirely new communities of interested viewers.5 This process can create a positive feedback loop: increased views lead to more impressions in user feeds, which in turn generates even more views.5 When hashtags are used thoughtfully, they essentially optimize content for discovery within the TikTok ecosystem, making it easier for genuinely interested viewers to find and engage with the videos.3 Selecting the most appropriate hashtags can broaden a video’s reach and substantially boost overall engagement.3 Ultimately, this strategic use of hashtags has the power to transform an ordinary post into a viral sensation, connecting creators with a global audience eager for their content.3 Trending hashtags, in particular, enhance a video’s findability, leading to greater visibility.6 They serve as signposts, directing viewers interested in specific subjects directly to the relevant videos.6 The description of this self-perpetuating cycle of visibility and engagement emphasizes the significant return on investment for creators who dedicate time and effort to their hashtag strategy. This process of optimizing content for discovery mirrors the principles of search engine optimization, highlighting the strategic importance of hashtags for maximizing reach on TikTok.
Trending hashtags represent the current pulse of TikTok, capturing the attention of a vast user base. Incorporating these hashtags into relevant content can significantly boost a video’s visibility, allowing it to be seen by a large and diverse audience in a short period.6 TikTok’s algorithm often favors content that utilizes popular trending hashtags, potentially giving it a push into more user feeds. The most reliable way to discover what’s currently trending is through TikTok’s own Creator Center, a dedicated resource that provides insights into popular hashtags and emerging trends.4 Beyond the platform itself, various third-party tools and websites analyze current TikTok trends and offer suggestions for hashtags that are likely to increase a video’s reach.3 Common examples of general trending hashtags frequently include terms like #fyp, #tiktok, and #TikTokviral.7 Additionally, creators should be mindful of hashtags that gain traction around specific events, seasonal changes (such as the arrival of spring), or popular platform-wide challenges.9

This table provides a snapshot of the types of hashtags that might be trending in a specific month, highlighting the mix of general, seasonal, and event-driven trends that creators can consider. The availability of TikTok’s Creator Center as a native tool for discovering trending hashtags makes it a primary and trustworthy resource for creators. Furthermore, the fact that trends are often tied to specific events and times of the year emphasizes the need for creators to remain agile and adapt their hashtag strategies to reflect current happenings.
While leveraging trending hashtags can offer a significant boost in visibility, it’s crucial to ensure that their use is genuinely relevant to the video’s content and overall theme.3 Creators should look for opportunities to participate in popular hashtag challenges, as these can be an effective way to tap into a wider audience and showcase their creativity.5 It’s also important to verify that the trending hashtags being used are still current and actively being used by the TikTok community.12 For those seeking to stand out, exploring content gaps within trending topics and offering a unique perspective can be a successful strategy.4 Simply using a popular hashtag for the sake of increased views, without any connection to the video’s content, can be counterproductive.1 This approach can confuse the algorithm and may even lead to the content being flagged as spam.1 Therefore, while capitalizing on trends is important, it should always be balanced with the need to create hyper-specific content that resonates with a defined niche.4 Even when participating in trends, creators should strive to connect the content back to their brand or unique style, maintaining authenticity and brand consistency. The need for relevance cannot be overstated; using trending hashtags that don’t align with the content will likely result in attracting viewers who are not genuinely interested in the creator’s niche, leading to low engagement and potentially harming the creator’s long-term growth.
Niche hashtags, on the other hand, are highly specific keywords or short phrases that cater to a particular topic, interest, or community.4 These hashtags are incredibly valuable for connecting with an audience that is deeply and genuinely interested in the creator’s specific content.4 Examples of niche hashtags include terms like #PlantMoms for plant enthusiasts or #professionaldogwalker for those in the dog-walking industry.4 Often, these niche hashtags are longer and more specific phrases, sometimes referred to as “long-tail keywords” in the context of search engine optimization.4 This concept from SEO highlights the fact that these longer, more specific search terms often indicate a higher level of user intent, meaning that users searching for these terms are likely looking for very specific information or content. By using such niche hashtags, creators can attract a more qualified and engaged audience that is actively seeking out their particular type of content.
Discovering relevant niche hashtags requires a proactive and multifaceted approach. The TikTok search bar itself is a powerful tool; by typing in keywords related to a specific niche and exploring the “Hashtags” tab, creators can uncover a wealth of relevant tags.2 Observing what hashtags other successful creators within the same niche are using on their popular videos can also provide valuable insights.4 Dedicated research into hashtags that are specific to the content being created is also essential.12 Furthermore, various hashtag generator tools available online can assist in identifying related niche hashtags that might not have been immediately obvious.1 Monitoring the hashtags used by competitors and analyzing their performance can also inform a creator’s own hashtag strategy.1 Engaging with the existing audience and paying attention to the hashtags they use when discussing related topics can also provide valuable inspiration.4 Creators should also look for potential content gaps within their niche; sometimes, less commonly used hashtags can represent underserved areas of interest.4 Exploring broader, category-specific hashtags can also reveal top-performing content within those smaller communities, offering further inspiration.1 This multi-pronged approach, combining direct platform research with the use of external tools and an understanding of competitor and audience behavior, is key to uncovering the most effective niche hashtags.
Beyond discoverability, niche hashtags play a crucial role in building a loyal community on TikTok. For businesses and brands, creating a unique, branded hashtag can be an excellent way to foster a sense of community around their identity.1 Encouraging followers to use this specific hashtag when they create content related to the brand helps to build a dedicated space within the platform.1 Consistently using relevant niche hashtags in their own content also helps creators to establish an association between those terms and their brand or area of expertise.2 Launching a hashtag challenge that encourages audience participation using a specific niche hashtag can also be a highly effective way to generate user-generated content and further strengthen community bonds.5 Branded hashtags, therefore, serve a dual purpose: they enhance discoverability for brand-related content and, more importantly, they cultivate a sense of belonging and encourage active participation from the audience, turning viewers into engaged community members and potential brand advocates.
The most effective TikTok hashtag strategy often involves a strategic combination of both trending and niche hashtags.1 This approach allows creators to leverage the broad reach of trending hashtags to gain initial visibility while simultaneously tapping into the highly engaged audience reached by niche hashtags.11 This synergy creates a balance between maximizing the potential for widespread discovery and ensuring that the content resonates with those who are most likely to be genuinely interested in the specific topic.
Crafting effective hashtag combinations involves several practical considerations. A common recommendation is to aim for a mix of around three to five relevant hashtags per video, as this often strikes a good balance between discoverability and not overwhelming the viewer.4 It’s generally advisable to start with hashtags that are very specific to the video’s industry or content topic.6 If the video addresses a particular problem or offers a solution, including hashtags that reflect that can also be beneficial.6 Thinking about the target audience and including hashtags that they might be actively searching for is another important aspect.6 Utilizing a combination of broad, popular keywords (short-tail) and more specific, niche keywords (long-tail) can further enhance reach and engagement.4 It’s crucial to prioritize adding the most important hashtags directly into the video caption, as these tend to carry more weight with the TikTok algorithm.4 If the caption character limit is reached, adding a few extra relevant hashtags as the very first comment on the video can serve as a useful supplementary tactic.4 While it’s technically possible to include a large number of hashtags, a more focused selection of highly relevant tags is generally more effective for reaching the intended audience and avoiding a cluttered appearance. Using the first comment for additional hashtags provides a practical way to maximize hashtag visibility when caption space is limited.
Examining successful TikTok content can provide valuable insights into effective hashtag strategies. For instance, the example of user Pokertrick1 using the popular #fyp hashtag alongside the more niche #magictrick demonstrates the power of combining broad reach with targeted relevance.5 Similarly, Jellycat’s success in building a community around their branded hashtag #jellycat highlights the effectiveness of niche-focused branding.1 Boosted’s strategy of using a mix of general trending hashtags with more specific and branded ones also illustrates a well-rounded approach to maximizing reach.12 Exploring examples from diverse industries like real estate, marketing, law, fashion, and hospitality reveals the specific types of hashtags that these sectors use to connect with their respective target audiences.13 By actively seeking out and analyzing successful content within their own niche, creators can gain valuable insights into hashtag strategies that are proven to work within their specific content category.
Analyzing the hashtag strategies employed in successful TikTok videos often reveals a strong emphasis on relevance to the video’s content. There is typically a careful balance between using broad, high-volume hashtags to increase initial visibility and employing more specific, lower-volume hashtags to attract a genuinely interested audience. The use of branded hashtags, where applicable, often plays a significant role in fostering community engagement and enhancing brand recognition. While specific performance metrics might not always be readily available, the overall engagement of these successful videos (in terms of views, likes, comments, and shares) often serves as an indicator of the effectiveness of their hashtag strategy. This process of deconstructing the hashtag choices of successful creators can provide valuable lessons and inspire creators to adapt similar strategies to their own content.
To further refine their hashtag strategy, TikTok creators can adopt several advanced tips and tricks. While there’s no definitive magic number, aiming for around three to five highly relevant hashtags in the video caption is generally considered a best practice.4 It’s important to remember that hashtags placed directly in the caption tend to be given more weight by the algorithm compared to those added in the comments.4 Given the limited character count for captions, prioritizing the most impactful hashtags is crucial.5 If there are additional relevant hashtags that couldn’t fit in the caption, adding them as the first comment on the video is a useful workaround.4 Thinking strategically about the placement of hashtags within the caption, perhaps incorporating them naturally into the text, can also enhance engagement.1
Conversely, creators should be mindful of hashtags to avoid. Using hashtags that have no relevance to the video’s content can confuse the algorithm and may even lead to the content being flagged as spam.1 Overly broad or generic hashtags that are associated with millions of videos might also lead to the content getting lost in the sheer volume.4 Most importantly, it’s essential to steer clear of banned hashtags, as their use can severely limit a video’s visibility and potentially harm the creator’s account standing.1 Beyond the most obvious hashtags, exploring variations of popular terms and utilizing long-tail keywords can unlock new avenues for reaching specific and engaged audiences.4 These longer, more specific phrases often connect with users who have a clear intent and are actively searching for that particular type of content.
Fortunately, a variety of tools and resources are available to assist TikTok creators in their quest for the perfect hashtags. TikTok’s own Creator Center remains a primary source for identifying trending hashtags and understanding platform analytics.4 Basic hashtag generator tools like TikTok Hashtags can provide a starting point for discovering related terms.1 For more sophisticated suggestions, AI-powered tools such as Ahrefs’ AI hashtag generator and Meltwater’s AI Hashtag Hero generator analyze content and audience data to provide intelligent hashtag recommendations.1 Mobile applications like Hashtag Expert offer another convenient way to discover relevant hashtags based on keywords and categories.3 Platforms like Brand24 provide comprehensive hashtag search, monitoring, and analytics capabilities.6 Social media management tools like Buffer and Sendible often include features to help users find, organize, and even schedule hashtags.1 Additionally, websites like IQ Hashtags, HypeFury, and DashSocial offer dedicated hashtag research functionalities.7

By understanding the fundamental function of hashtags, strategically leveraging both trending and niche options, and utilizing the various tools available, creators can significantly enhance their content’s visibility, engagement, and overall impact. Consistent and thoughtful application of these principles will not only lead to immediate gains in views and interactions but will also contribute to the long-term growth of a loyal and engaged community on TikTok.
