SITE.su is an online marketplace for premium domain names, offering a large selection of keyword domains in the .ru, .su, and .рф zones. Customers can browse listings, search by one or more terms, use advanced search options, or download the full domain catalogue as an Excel file. The service supports both immediate purchase and domain rental, with online transactions and assistance available through its Help section and chat.

Purchasing a domain transfers its administrative rights to the buyer. Renting allows the customer to set the domain’s name servers, and the rental agreement includes priority rights to buy the domain during the rental period at a price fixed in the contract. Rental terms can extend up to 50 months. Listings include information such as purchase and monthly rental prices, domain age, and search-related rating data. Customers can also ask questions about a domain or submit a price offer. SITE.su presents its marketplace as a practical resource for individuals and businesses seeking a domain for an online project or brand.
