To use hashtags effectively in 2024, start by researching trending, niche, and branded hashtags relevant to your content and audience. Use a balanced mix of these to reach a broader and more targeted audience. Limit the number of hashtags to avoid spammy appearances; around 5-10 per post is ideal. Engage with users through hashtag searches to build community and boost visibility. Regularly analyze hashtag performance to refine your strategy, focusing on those that drive engagement and reach. Keep up with platform-specific hashtag trends for optimal results.
