Publish on Your Own Site, Syndicate Elsewhere—known as POSSE—asks creators to post first on their personal domain before pushing copies to platforms such as Twitter, Instagram, or Mastodon. By keeping the canonical version under one’s control, readers can follow links back to the original article, preserving ownership and enabling direct interaction without relying on any single silo.

Putting content on a self‑hosted site reduces dependence on third‑party terms of service and improves search visibility, because search engines index the author’s domain rather than fragmented feeds. Tools such as Bridgy Publish, the PHP POSSE namespace, and Python’s SiloRider automate cross‑posting while attaching permashortlinks that point to the source. Reverse syndication via backfeed pulls comments from the silos back to the original page.

Implementations range from manual cross‑posting on WordPress.com to webhook‑driven Ghost plugins that push new posts to Mastodon and Bluesky. Developers can expose a “posts‑elsewhere” section linking each syndicated copy, or rely on invisible automation that previews the outbound payload before publishing. With these patterns, creators retain a permanent, searchable home for their work while still leveraging social platforms’ engagement features.
