# Improve SEO with Host Header Override Rules

Support a single hostname across multiple realms by creating a Host Header Override Rule for sites that use an external content delivery network (CDN). This rule replaces unique hostnames with a common hostname to maintain the single-hostname setup. Maintaining a single hostname improves SEO for your site.

**Where:** This change applies to B2C Commerce.

**How:** In Business Manager, go to **Administration** | **Sites** | **Embedded CDN Settings**. On the Host Header Override Rules tab, create your rule. Then modify your external CDN to route traffic to the proxy zones for each locale.
