Subdomains in SEO and security
Subdomains (blog.example.com, app.example.com) can be treated as separate sites by search engines depending on internal linking and signals.
Security teams map subdomains to find shadow IT and misconfigured services. SEO teams ensure important subdomains are in sitemaps, robots.txt, and Search Console properties as needed.
