SITE.su is an online marketplace for premium domain names, offering a catalog of more than 39,000 domains in the .ru, .su, and .рф zones. Customers can browse and search for keyword-based domain names, review available options, and download the full catalog in Excel format.

A purchase transfers the domain’s administration rights, while rental allows the customer to use their own name servers and includes a contractual priority right to buy the domain at a price fixed in the agreement. Rental agreements can last up to 50 months.

Listings include information such as purchase and rental prices, domain age, and SEO-related ratings based on search data and keyword indicators. SITE.su also provides expanded search, online assistance, contact options, and a way to ask questions or propose a price for a domain. Its services are designed to help businesses and individuals find and secure domain names for websites, brands, or personal projects.
