Instagram's algorithm has evolved significantly, and the hashtag strategy that worked in 2020 may actually hurt your reach today. Here's what the data says about hashtags in 2025.
How Many Hashtags Should You Use?
Instagram's own recommendation is 3-5 hashtags. Excessive hashtag use (20-30) is now associated with lower reach, as it signals spam-like behavior.
Types of Hashtags
Niche hashtags (under 100K posts): highest conversion. Industry hashtags (100K-1M): good discoverability. Trending hashtags: high competition. Brand hashtags: build community.
Research Your Hashtags
Use Instagram's search to explore hashtag communities. Look for active, relevant communities where your target audience participates.
