SITE.su is an online marketplace for premium domain names, offering more than 39,000 domains for businesses and individuals seeking a distinctive web address. Its listings include keyword-focused domains in the .ru, .su and .рф zones, available for immediate purchase or monthly rental. Buyers can complete a purchase online, with the domain’s administrative rights transferred to them. For rentals, customers assign their own DNS servers, and the rental agreement gives them priority rights to buy the domain during the rental period, with the purchase price fixed in the contract. Rental agreements can last up to 50 months.

The website helps visitors find suitable names through keyword and extended searches, and provides options to view or download the full domain list, including a spreadsheet with domain information. Customers can ask questions or propose a price through the site’s contact form, with help and online chat available in the Help section. SITE.su presents domain age and search-related indicators to help customers assess listed names.
