Instagram may not be promoting your reels anymore because you might be using the wrong type and number of hashtags. It's important to choose relevant hashtags that are specific to your content and target audience. Using too many or unrelated hashtags can actually decrease your reels' visibility. Additionally, Instagram allows up to 30 hashtags per post, so it's best to maximize this limit to increase your chances of getting discovered by more users.
To improve your reel's visibility, try using a variety of specific and popular hashtags that are relevant to your content. Focus on quality over quantity, making sure that each hashtag is highly relevant to your reel. Avoid using too many unrelated or generic hashtags as they can dilute the visibility of your content. By optimizing your hashtag strategy, you can increase the chances of Instagram promoting your reel again.
