Custom Domain Setup
Setting up a custom domain gives your site a professional, branded URL.
DNS configuration
After adding your domain in Vercel, configure these DNS records at your registrar:
For apex domain (yourbrand.com):
- Type: A
- Name: @ (or blank)
- Value: 76.76.21.21
For www subdomain (www.yourbrand.com):
- Type: CNAME
- Name: www
- Value: cname.vercel-dns.com
SSL certificates
Vercel automatically provisions SSL certificates via Let's Encrypt:
- Certificate is issued within minutes of DNS verification
- Automatically renewed before expiration
- Supports both apex and www domains
- No manual configuration required
Common DNS issues
Domain not resolving:
- Verify DNS records are correct (no typos)
- Wait up to 48 hours for propagation (usually 15-60 minutes)
- Use a DNS checker tool to verify records are visible globally
SSL not working:
- Ensure DNS is fully propagated first
- Vercel retries certificate issuance automatically
- Allow up to 1 hour after DNS propagation
If your registrar provides its own CDN or proxy (like Cloudflare), disable the proxy for your Vercel domain. Running two CDNs causes conflicts and may break SSL.
Redirects
Configure redirects in Vercel to ensure:
http://redirects tohttps://- Non-www redirects to www (or vice versa, pick one)
- Old domain redirects to new domain (if migrating)
