A parked domain is an additional domain name that points to an existing website. A subdomain is a prefix like "blog.example.com" is added to your main domain.
Parked domains are an excellent way to preserve valuable domain names, collect misspelled traffic, and safeguard brand identification. Subdomains maintain the main domain tidy and structured by helping to segment information, such as blogs, forums, or support areas.
Parked domains don't impact SEO directly since they don't add unique content. Subdomains can impact SEO positively or negatively depending on content and structure.
Managing parked domains is simple. They usually don’t require much maintenance. Subdomains require regular updates and maintenance since they host content separate from the main domain.
Parked domains are usually cheaper as they don’t require separate hosting. Subdomains share hosting with the main domain but can increase costs due to content management.
Parked domains pose minimal security risk. Subdomains require the same security measures as main domains.
