SITE.SU is an online marketplace specializing in premium keyword domains, with a catalogue of more than 40,000 domain names across the .ru, .su and .рф zones. The store helps individuals and businesses find memorable web addresses for projects, brands and online services, offering both immediate purchase and rental. Rental is arranged by assigning the customer’s DNS servers, while purchased domains are transferred online. Some rental options include a guaranteed right to buy the domain later, providing flexibility for customers who want to establish an online presence before committing to ownership.

Visitors can browse the full domain list, download catalogue data, or use advanced search to find names by keyword, related terms and translations. Listings display purchase and monthly rental prices, and may include domain age and rating information. Customers can add a domain to the appropriate cart for an immediate transaction or contact the store to ask questions and propose a price. Registration, account access, assistance and online chat are available through the site’s help and contact sections.
