Microsoft's Bing and JiWire have a proposition for you. Free WiFi in exchange for using Bing. Interested? The promotion would give users free Internet access at participating hotspots if they do just one search with Bing. In conjunction with JiWire’s advertising network, Microsoft will be extending the offer to various hotels and airports.

The campaign was started in September at several thousand locations. It managed to attract between 30 and 40 percent of visitors to the hotspots. This is extremely high, as most ads only get interaction from 0.1 to 0.2 percent of people. Microsoft reportedly plans to continue with the promotion, which is a part of JiWire’s Ads for Access campaign. The campaign allows companies to give customers something in exchange for their time. This can be taking a survey, watching a video ad, or (in this case) using the Bing search engine.

The next time you’re in an airport, keep an eye out for these ads. It could get you free access courtesy of a certain Redmond software giant.
