SITE.su is an online marketplace for premium domain names, offering a catalog of more than 40,000 domains, primarily in the .ru, .su, and .рф zones. The service helps businesses and individuals find a memorable web address, with domains available for immediate purchase or rental. Customers can browse the full catalog, download a domain list in Excel, or use advanced search to filter options. Listings may include purchase and monthly rental prices, domain age, and indicators of search and keyword performance.

Purchasing a domain transfers its administration rights to the buyer through an online process. Rental allows customers to set their own name servers and includes a contractual priority right to purchase the domain during the rental period, at a price fixed in the agreement. Rental agreements can last up to 50 months. SITE.su also provides a contact form for questions or price offers, along with help and online chat. Its catalog includes names such as goroskopiky.ru and related alternatives, giving customers a range of choices for their projects.
