Adsense promotion is 100 US dollars, while Alimama promotion is 20 RMB. It has been proven that Alimama's promotion is more popular than Adsense's, at least on the surface. Adsense canceled its global Adsense promotion plan in August, and this policy is really confusing. If the price of 100 US dollars is a bit high, it can be reduced like Firefox did, 20 US dollars or 10 US dollars, all of which can encourage others to promote. There is no need to cancel this promotion. Either it's saturated or the failure of the policy itself. If Adsense is confusing, Alimama is even more confusing.
