This webpage is meant to be used in conjunction with the How do I add a UET tag to my website? Microsoft Advertising Help article.
As the webpage loads, it triggers the UET tag, resulting in a number of HTTP requests. The most important request is to "bat.bing" (the one that looks like "http://bat.bing.com/action/0?ti=..."). This request tells Microsoft Advertising about the user visits to your webpage. You can use third-party tools such as Fiddler to monitor all the requests that your browser is making when your webpage loads.
