Ask HN: Migrating old Substack posts to my own blog, have a question
Praddy Monday, December 22, 2025I’m moving my older posts from Substack to my personal blog and I want Google to treat my blog as the primary source going forward.
Constraints:
- Substack doesn’t support canonical URLs (so I can’t point Substack → my blog).
- I don’t want to use a custom domain on Substack.
- Going forward, I want Substack only as the newsletter, and my blog as the SEO winner.
I’ve seen the “ghost post” approach (replace most of the Substack post with a teaser + link), but I don’t want to delete/gut the original Substack content because I still want readers there to have the full post.
Is there any way or a hack to get this donee??
