Hashtags are integral to TikTok SEO as they serve multiple critical functions. Firstly, they help categorize your content, making it easier for TikTok’s algorithm to identify and surface your videos when users search for specific topics or themes. This categorization is essential for reaching viewers who are interested in your content’s subject matter.   Secondly, hashtags increase the reach of your videos by connecting them to broader conversations and trends on the platform. By using trending hashtags, you can tap into existing streams of engagement and visibility, allowing your content to be discovered by a wider audience. However, it’s important to balance trending hashtags with more specific ones that accurately represent your video’s content, as this ensures that your reach to relevant audiences is maximized.   Additionally, strategic use of hashtags can also introduce your content to niche communities and interest groups on TikTok, which are often highly engaged. Participating in these smaller, more focused groups can lead to higher engagement rates, as your content is more likely to resonate deeply with a targeted audience.   Ultimately, the careful selection and combination of hashtags are crucial for maximizing the discoverability and reach of your TikTok videos, making them a foundational element of effective TikTok SEO.
