SITE.su is an online marketplace specializing in premium domain names. The store offers a selection of around 40,000 domains, including keyword-based names in the .ru, .su, and .рф zones. Customers can browse available domains, use advanced search tools, view a full catalogue, or download a domain list for review.

The marketplace supports both immediate online purchases and domain rentals. Rental arrangements are made by assigning the customer’s DNS servers, and the site states that rentals include a guaranteed right to buy. Purchased domains are transferred immediately through the online process. Listings display prices in rubles, with some also showing details such as domain age and available rating or search statistics.

Customers can submit questions about a specific domain, propose a price, or contact the store through the help section, which includes an online chat. The site also provides account registration and login features, along with guidance on searching and completing transactions. SITE.su is designed for people seeking domain names for websites, businesses, or personal projects.
