In China, the advertising targets vary from super rich class(billionaires thousands people), rich class(millionaires 470,000 population), uper middle class(avg income $100K/year multi millions), middle class(avg income $10K/year tens of million people),medium people (avg income $3k~8K/year hundreds of millions,), low income class(lower than $3K/year hundreds of millions), young people(no or few income, but can spend $1K~$100K/year hudred millions).
Without clarifying the ads target, it is not good to claim the ad prices high or low. In some special categories, the ppc are much higher in Europe, Japan, China than US. Sorry, I do not disclose more here.
In the long run, the cctld domain names and IDNs will rise very much.
I am not surprised with the sale of the sofa idn. Just congratualations to the buyer and seller!
The ppc/ppv prices depend on the ROI not only depend on income level of the targeted people,I would say.
