How to Set Up a Subdomain for Website Builders (CapGo, Webflow, Framer, Wix)
If you want to set up a subdomain (e.g., site.yourdomain.com) for your website using tools like CapGo, Webflow, Framer, or Wix, here’s a detailed guide:
🧭 1. Prerequisites
Before you start, make sure you have:
✅ A registered main domain (e.g., yourdomain.com)
Your domain registrar can be GoDaddy, Namecheap, Alibaba Cloud, Tencent Cloud, etc.
✅ Access to your domain’s DNS management panel.
✅ Your website ready (e.g., after publishing on Webflow) with a target address.
Webflow or other tools usually provide instructions for DNS records, like proxy.webflow.io.
⚙️ 2. Find Subdomain Setup Instructions in Your Website Builder
For example, using CapGo or Webflow, the service team will provide the DNS records to add, usually like this:
| Type | Name (Host) | Value / Points to |
|---|---|---|
| CNAME | site | proxy-ssl.capgo.com |
🌐 3. Add the Subdomain DNS Record at Your Domain Registrar
Go to your domain DNS management page (GoDaddy, Cloudflare, Alibaba Cloud, etc.) and add the following record:
| Record Type | Host | Value | Notes |
|---|---|---|---|
| CNAME | site | proxy-ssl.capgo.com | Address provided by CapGo |
Notes:
- If using Cloudflare, make sure the “Proxy Status” is set to DNS Only (gray cloud), otherwise Webflow/CapGo may not verify.
- DNS propagation may take anywhere from a few minutes to several hours.
🔍 4. Verify Subdomain in CapGo
- Inform the CapGo team that you have added the DNS records.
- Once DNS propagation is complete, the status should show “Connected”.
- Click “Publish to site.yourdomain.com” to make your website live on the subdomain.
🧩 5. Common Issues
| Issue | Solution |
|---|---|
| ❌ Verification fails | Wait 30 minutes for DNS propagation and try again |
| ⚠️ SSL invalid | Enable SSL in Webflow |
| 🌐 Subdomain shows errors | Check if the correct CNAME record is added |
| 🕓 Slow propagation | Use <code>dnschecker.org</code> to verify global propagation |
💡 Tips
- If you want your main domain (
yourdomain.com) to redirect to the subdomain (site.yourdomain.com), set up a URL redirect. - If managing DNS via Cloudflare, you can add the CNAME and enable Webflow’s automatic SSL.
- Keep your subdomain names simple and clear (e.g.,
site.,web.,app.).
This guide ensures your website builder subdomain is configured correctly for both functionality and SEO readiness.
