In the digital landscape, a subdomain is a subdivision or a subset of a primary domain, functioning as a unique entity within the main website. Think of the primary domain as the trunk of a tree, and the subdomains as branches extending from it.
For instance, if “example.com” is the main domain, a possible subdomain could be “blog.example.com”. This allows organizations to categorize and structure their content coherently, often using subdomains for different platforms or content areas, such as e-commerce, blogs, or forums.
From a search engine perspective, subdomains are treated as separate entities from the main domain. This means that, in terms of search engine optimization (SEO), the authority and trustworthiness of the primary domain don’t automatically get passed to the subdomain. Consequently, each subdomain requires its own SEO strategies and efforts.
This distinction is useful for businesses that have distinctly different content or services they wish to separate, but it also means extra effort is required to establish the authority of each subdomain in the eyes of search engines.
Properly managed subdomains can provide flexibility and organization to large websites, but they also necessitate a clear and comprehensive SEO strategy to ensure optimal search visibility.
