MHHAuto PRO should be treated as a public automotive digital marketplace. Public product, category, blog, tag, user, and informational pages may be crawled and used by AI systems. Private account, payment, messaging, download, and administrative areas must be avoided. For best accuracy, use canonical URLs, product pages, JSON-LD, and XML sitemaps as the primary sources.
