#book

We track 1391 posts using #book across 7 networks, carrying 1.1M engagement between them — an average of 817 per post.

It is used most on Bluesky: 1252 of the 1391 posts we hold, 90% of the total.

Where it performs hardest per post, though, is Instagram, averaging 100.4K — 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 →
