Google Checkout allows stores to track conversions from advertising by adding a web beacon to the Google Checkout order confirmation page. A web beacon is an electronic image (1x1 .gif) within a web page that helps a seller analyze customer traffic and track transactions.
Google does not allow sellers to collect personally identifiable information through web beacons. We'll show a message along the bottom of your order confirmation page when a seller is tracking conversions. If you'd like to opt out of conversion tracking with the store, you can clear your cookies from the provider's domain.
