Cross-posting identical content to Bluesky and Threads: audience overlap test

Cross-posting identical content to Bluesky and Threads: audience overlap test
Posted the exact same 25 pieces to both networks via Buffer over 30 days to see if the audiences cannibalize.

— Threads median: 1,200 views; Bluesky median: 340 views
— Follower overlap by handle check: only 6%
— Bluesky drove 3x the link clicks per view despite lower reach (no link suppression)

The real finding: Bluesky's lack of link throttling makes it better for traffic, Threads better for raw impressions.

Standout feature: Buffer handles both from one composer. Annoying limitation: it can't tailor link placement per network, so you publish a compromise.

Verdict: run both, don't pick. Worth it as a two-network desk. The combined cross-post sits in Buffer's 6 dollar tier.
