Buyers can browse listings, search by words or themes, use advanced search options, and view or download the full domain catalogue.

SITE.su offers both immediate purchases and monthly rentals. A purchase transfers domain administration rights online, while rental allows the customer to change the domain’s name-server settings. Rental agreements include a priority right to buy the domain during the rental period, with the purchase price fixed in the contract; rental terms can last up to 50 months. Listings show purchase and rental prices, and may also include domain age and search-related indicators.
