Blog on a Subfolder versus a Subdomain in Technical SEO
A blog can live in a subfolder (yoursite.com/blog) or on a subdomain (blog.yoursite.com). Search engines can treat a subdomain as a partly separate site, so a subfolder usually keeps the authority earned by content on the same site as the pages that sell, while a subdomain mainly suits genuinely separate products or technical constraints.
