We track 7004 posts using #astronomy across 9 networks, carrying 276.2M engagement between them — an average of 39.4K per post.
It is used most on Instagram: 3276 of the 7004 posts we hold, 47% of the total.
Where it performs hardest per post, though, is TikTok, averaging 201K — so the tag is posted most in one place and lands best in another, which is exactly the difference worth knowing before choosing where to use it.
Ranking comes from the posts themselves rather than from how often the tag appears, and it is recalculated as new posts are collected. How we measure this →
