As Chinese companies and brands aggressively seek higher retention and traffic volume from overseas, purchasing highly-targeted ad space quickly is becoming more and more of a necessity to maintain their rapid growth. AppFloodโs real-time bidding exchange and demand-side platform claims to be the first for mobile in China, with big clients like search engine Baidu and software maker Kingsoft. And itโs not just a one-way street; AppFlood allows foreign companies to break into the Chinese mobile market as well, focusing on all companies who want to bridge the East and the West.
โBased on our experience, the trend of Chinese firms trying to reach international audiences is rather new,โ says Si Shen, CEO of AppFloodโs parent company PapayaMobile. โGoing global is unprecedented and sudden considering that Chinese companies have traditionally been risk-averse.โ
In addition to AppFlood in China, Singaporeโs Vserv.mobi also launched a real-time bidding platform today. This one aims to give emerging countries, especially in Southeast Asia, access to the global mobile advertising market. So what is real-time bidding, and why are these services suddenly popping up?
By now weโve all realized that internet advertising is growing increasingly targeted. Depending on where we live, what devices we use, which websites we visit, and what products we purchase online, the advertisements we see change accordingly.
But as the internet grows larger both in terms of users and digital real estate, so does the disconnect between the people buying ad space (brands, networks, and agencies) and the people selling it (app publishers, SDK publishers, and websites). In such a massive landscape, how do the two parties find the best match for what ads are displayed when, where, and how at the right price? Daunting as the task may seem, itโs also increasingly important to buy ideal ad space fast.
One solution thatโs more and more popular these days is real-time bidding (RTB). Itโs a sort of near-instant automated auction house where those with ad space sell it to companies who want to reach users. RTB first appeared about four years ago and has been a fast growing method led by OpenX, Google, and Yahoo in the west, but the technology has lagged behind on mobile. Shen explains major players like Sina, Baidu, and Tencent have yet to offer RTB on mobile because they are very protective of the types of ads shown and their placement in apps.
RTB on the web has been around in China since 2011. By 2012, RTB accounted for just 0.3 percent of Chinaโs total display advertising business, but the popularity of RTB is undoubtedly growing. In 2013, RTB was between one percent and 1.5 percent of Chinaโs total display advertising business in 2013.
A first in China, AppFlood has partnered with a major western RTB exchange OpenX. AppFloodโs current mobile ad network serves more than 145 million monthly active users and 9,000 Android developers.
Precise matching in under a second

On the demand side, brands โ or the agencies and networks they work with โ set the criteria for the type of user they want to reach, and how much they are willing to pay to reach him or her. For instance, Iโm a male in my 20s who uses an Android smartphone and recently bought a plane ticket to a resort city in southern China. That info might put me in the target audience for a Samsung ad, but Iโd bet a local travel booking company like Ctrip is willing to pay even more to show me an ad. Ctrip can submit a high bid of $3, while Samsung might just bid $0.50 since my traffic isnโt as valuable to it.
