Facebook Inc wants its users in India to hang up on advertisers.
The social networking company is testing a new type of ad in the country that allows mobile phone users to click a button that calls a brand advertiser, immediately hangs up and then receives a return call.
The return call delivers pre-recorded audio messages about everything from sponsored cricket scores to information about shopping discounts, minimising data charges for the user.
The so-called "missed call" ad was specially created by Facebook to appeal to users in the world's second-most populous country, and potentially in other emerging markets.
Facebook has more than 100 million users in India, with the majority accessing the service on so-called feature phones, which lack touchscreens and other capabilities of higher-end smartphones.
The ads are part of Facebook's effort to bolster its business in countries such as Brazil, India and Indonesia, which could help Facebook boost its overall revenue.
Roughly 84% of Facebook's 1.28 billion monthly users are outside the United States and Canada, but the average revenue per user that Facebook generates in international markets is significantly lower than in the United States and Canada.
Facebook Chief Operating Officer Sheryl Sandberg is in India this week visiting the company's offices and meeting with partners. Last week, Facebook rival Google Inc announced plans to bolster its business there by developing a sub-$100 smartphone that uses its Android software.
Facebook has optimized the ads on its service to work on slower wireless connections in emerging markets and it is improving its tools in individual countries to help marketers better target different groups of users.
The company has also recently opened sales offices in Colombia and Indonesia and it is working with measurement firm Nielsen to measure how mobile phone users react to ads.
In early tests of the missed call ads by L'Oreal-owned haircare product Garnier Men, the ads led to a 2.5 times year-on-year increase in online sales, according to Facebook. In the coming months, Facebook said it plans to make the missed call ads more widely available.
