Our website uses Google Conversion Tracking. If you clicked on an ad delivered by Google on our website, a cookie is placed on your computer by Google AdWords. The cookie for conversion tracking is placed when a user clicks on an ad delivered by Google. These cookies expire within 30 days and are not personally-identifiable. If the user visits certain pages on our website and the cookie has not yet expired, we and Google will be able to recognize that the user has clicked on the ad and proceeded to that page. Every Google AdWords customer gets a different cookie. Cookies cannot therefore be tracked across sites by AdWords customers. The information obtained using the conversion cookie is used to create conversion statistics for AdWords customers who have opted in for conversion tracking. Customers are given an overall number of users who have clicked on their ad and proceeded to a page tagged with a conversion tracking tag. However, they will not receive any information that can personally identify users.
