A few days ago, when talking about John Chow's blog revenue report, I mentioned that one should be willing to invest money in promoting their website. However, doing Google AdWords can be too costly, and most webmasters probably can't afford it. Today, I will introduce a cost-effective promotion platform: Youdao Search Promotion by NetEase. Youdao Search Promotion is currently having a big sale, where you only need to pay one yuan to get 100 yuan worth of promotion credits.
