SITE.su is an online marketplace for premium domain names, offering a large selection of keyword-focused domains in the .ru, .su, and .рф zones. The site presents more than 40,000 domains for customers seeking a web address for a business, project, or online brand. Visitors can browse available names, search by words or other parameters, view related transliterations and synonyms, and download a complete domain list in Excel format.

SITE.su supports both domain purchases and monthly rentals. Purchases are completed online, with domain administration rights transferred immediately. Rental gives the customer the right to change the domain’s name-server settings, and the rental agreement includes priority rights to buy the domain during the rental term. The purchase price can be fixed in that agreement, which may last up to 50 months. Customers can use the online cart for immediate transactions or contact the marketplace to ask questions or propose a price. Help information and an online chat are available through the site’s support section.
