Tags with 50M+ posts. Use for maximum category reach. Examples: #onfire, #instagram.
Tags with 1M–10M posts. Best for discoverability among engaged, specific communities.

Each category page is designed for creators who want more precise hashtag matches for Instagram Reels, TikTok posts, YouTube Shorts, and other discovery-driven platforms.
Category-based research is stronger than relying on one generic viral list because it aligns the keyword cluster with the audience, niche, and content format.
That matters even more if you are checking whether hashtags still work on Instagram, how many hashtags should I use on TikTok, or which tags are actually relevant for the post you are publishing.
