What You Need to Know
How photographers and creators adapt skeets for Instagram
If your Bluesky post includes an image or video, that asset can go directly to Instagram.
The text caption needs to be rewritten — Instagram captions are longer, hashtag-heavy, and algorithm-optimized in a way that skeets are not.
For text-heavy Bluesky content, the practical workflow is: compose the skeet, then design a quote graphic or carousel slide with the text, and post that to Instagram.
Tools like Zapier or Dlvr.it can trigger Instagram posts when you post on Bluesky, but only if your content includes media.
Making your Instagram post feel native, not lifted
Instagram users expect polished visuals.
Do not screenshot a skeet and post it — that reads as lazy.
Instead, pull the core idea from your Bluesky post and reframe it for the grid: bold typography on a clean background, a short Reel hook, or a carousel that expands the original thought into multiple slides.
Use Instagram-relevant hashtags.
Bluesky's decentralized ethos and AT Protocol angle means nothing to an Instagram audience — translate the substance, not the format.
