There is unlimited space for advertising on Google and Baidu, and both online platforms are always trying to drive in more marketers. Among other strategies, these platforms offer their top-paying marketers incentives in the form of rebates. These rebates are meant to save marketers money on their paid adverts, and by doing so they incentivize the marketers to spend more money on more adverts. It is a win-win situation for everyone, and as a marketer you get to save a pretty penny.
