Cross-posting strategy#

1. First: Publish on Medium (or your primary platform)
2. Wait 24-48h: Let search engines index the original
3. Cross-post: Use canonical_url pointing to the original
4. Why: Avoids duplicate content penalties in SEO

1. Find publication's "Write for us" page
2. Follow their submission guidelines
3. Submit via Medium's story settings → "Add to publication"
