Though the registries are increasing the cost of domains every year, the online advertising revenues are declining even further, making it very difficult for domain investors to renew domains.
Only the large websites like facebook, instagram are able to charge high rates for online advertising.
Even autosurfing rates are higher, using just the computer, internet connection, users can make $0.01 a day or more with ebesucher . So instead of wasting money on domain renewal without much income, it is better to do autosurfing and make a few cents .
