Only core subdomains provide a competitive advantage to a company. Core subdomains are the company’s strategy for differentiating itself from its competitors. Generic subdomains, by definition, cannot be a source for any competitive advantage. These are generic solutions—the same solutions used by the company and its competitors. Supporting subdomains have low entry barriers and cannot provide a competitive advantage either. Usually, a company wouldn’t mind its competitors copying its supporting subdomains—this won’t affect its competitiveness in the industry.
