Addon Domain vs. Subdomain: Which Is Better for SEO?
An addon domain is a fully independent domain parked within the same hosting account (example.com), while a subdomain is a child directory of your main domain (shop.example.com).
People mix them up because both let you host separate sites cheaply, yet one looks like a brand-new property to Google and the other feels like “just another folder.”
Key Differences
Addon domains have unique DNS, separate analytics, and start at zero authority. Subdomains inherit some trust from the root, but Google often treats them as distinct entities, so link equity can split.
Which One Should You Choose?
Launching a new product line that needs its own brand? Go addon. Running a blog or support section that benefits from the parent’s reputation? Pick subdomain for faster traction.
Can I switch later without losing SEO?
Yes, with 301 redirects and patience, but expect 4–8 weeks of ranking turbulence.
Does Google prefer either for international SEO?
Neither; hreflang tags matter more than domain type.
