TL;DR
Hashtags remain a powerful way to increase discoverability and reach on Instagram — using relevant, trending, and niche tags boosts engagement.
Later’s analysis of over 18 million posts found that using around 20 hashtags (mixing high-volume, niche, and branded) yields strong reach — but the quality/relevance of the tags matters more than sheer number.
Use tools like Later Hashtag Suggestions and explore Instagram’s Explore page to discover hashtags aligned with your content and audience.
