Custom subdomain

Point blog.yourapp.com at your Blogizi blog with DNS + Vercel.

By default your blog lives at your-slug.app.blogizi.com. For a branded URL like blog.yourapp.com, connect a custom domain in project settings.

Setup steps

  1. Open Settings → DNS and choose Subdomain mode
  2. Enter your domain (e.g. blog.yourapp.com)
  3. Add the CNAME record shown in the dashboard at your DNS provider
  4. Click Verify — Blogizi registers the domain with Vercel and checks DNS propagation

DNS propagation

Changes can take up to 48 hours, though most providers update within minutes. The verify button re-checks status on demand.

Canonical URLs

Once verified, your blog's canonical URLs, sitemap, and OG tags use the custom domain automatically. Search engines will see https://blog.yourapp.com/post-slug as the canonical URL.

Prefer serving the blog under a path on your main domain instead? See Path mode (/blog).
