Targeted hashtags connect you with users who engage with similar content. Even if they haven't discovered you, they might check out your posts because they're already interested in that hashtag. If your content matches their expectations, you can gain new followers and expand your Instagram reach.

Start by creating high-quality, engaging content, using relevant hashtags, and interacting with your audience. Additionally, participating in Instagram engagement groups and collaborating with other users can help increase your following without the need to follow a large number of accounts.
