I am now descuss about adsense.I know this is affiliate program.If anybody click any adds of anybodies webpage so he receive some money from adsense.If his earn is minimum $100 so he eligible for this payment.Now my question is if any intenet users receive any money from adsense.
I think that adsense is a desperate program.Adsense program is profitable for google.But lose for the people who joined adsense program.
How can you know how much people drop by your page and how much people click adds.It is not possible for know the reall certainty.There are work one kind of google cleverity.
I know for this question google authurity may seriously angry with me.
