A domain alias is an alternative domain name that points to the same website as your main domain. For example, if your main site is `yourdomain.com`, you can set up `yourdomain.net` and `yourdomain.org` as aliases. Visitors who type any of these addresses will see the same website. This guide explains how to create and manage domain aliases in Plesk.

### Common Uses for Domain Aliases

- Pointing multiple TLDs to the same site (e.g., `.com`, `.net`, `.org`).
- Redirecting common misspellings to your main domain.
- Maintaining access to your old domain name after changing your primary domain.

### Adding a Domain Alias

1. Log in to **Plesk**.
2. Go to **Websites & Domains**.
3. Click **Add Domain Alias**.
4. Fill in the required fields:
   - **Domain alias name:** Enter the domain name to use as an alias (e.g., `yourdomain.net`).
   - **Sync DNS zone with the primary domain:** Check this to keep DNS records synchronized between the alias and the main domain.
   - **Mail:** Check this if you want the alias to also handle email for the same mailboxes.
   - **Web:** Check this if you want the alias to serve the same website content (keep this checked).
   - **Redirect with the HTTP 301 code:** Enable a permanent redirect from the alias to the main domain (recommended for SEO).
5. Click **OK**.

### Setting Up DNS for the Alias

After creating the alias in Plesk, you need to configure DNS at your domain registrar:

1. Log in to your **domain registrar** for the alias domain.
2. Point the alias domain DNS to the **same nameservers** as your main domain.
3. Alternatively, set an **A record** for the alias pointing to your Plesk server IP address.
4. Wait for DNS propagation (up to 48 hours).

### Important Notes

- A domain alias does not have its own website content — it shares the content of the main domain.
- You need a **separate registered domain name** for each alias.
- Using a 301 redirect is recommended for SEO to avoid duplicate content issues.
- Removing a domain alias does not cancel the domain registration.

### Troubleshooting

**Alias domain shows a different website or error page:**

- Verify the DNS records at your registrar point to the correct server IP.
- Check that the alias was created under the correct main domain.

**SSL certificate does not cover the alias:**

- You need an SSL certificate that includes the alias domain name (a multi-domain/SAN certificate or a separate certificate for the alias).
- Contact your hosting provider about adding the alias to your SSL certificate.
