SITE.su is an online marketplace for premium domain names, offering more than 40,000 domains, including keyword-focused names in the .ru, .su, and .рф zones. Customers can browse listings, search by terms or other parameters, view domain details, and download the full catalogue as an Excel file. The marketplace supports both immediate purchase and rental, with listed prices and contact options for questions or price offers.

Purchasing a domain transfers its administrative rights to the buyer. Rental provides the right to change the domain’s name server settings and includes a contractual priority right to buy the domain during the rental period. The purchase price is fixed in the rental agreement, which can run for up to 50 months. Listings may include information such as domain age, price, and search-related ratings based on Yandex Wordstat and Google and Yandex keyword indices.

SITE.su provides online checkout for purchases and rentals, along with registration, account access, customer support, and online chat through its Help section.
