They have over 50 million domains under management and their clients have access to 24/7 live support. They spend a lot of money on advertisements and are probably the most well known in their field.
The company operates and own their own equipment, which enables them to sell products instead of sub leasing them. Godaddy are much more than cheap domain suppliers, they offer help with site building, email services, domain hosting, SSL Certificates and help people resell their domains, whether they be on a VPS or shared server.
