Google Adwords Conversion Tracking

As a Google AdWords customer, Mareli Systems LTD uses Google Conversion Tracking, an analytics service provided by Google LLC (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA; "Google"). Google AdWords places a cookie on your computer ("conversion cookie") if you have reached our website via a Google Ad. These cookies expire after 30 days and are not used for personal identification. If you visit certain of our pages and the cookie has not expired, we and Google may recognize that someone clicked on the Ad and was redirected to our site. Each AdWords customer is attributed a unique cookie. Cookies therefore cannot be tracked through the websites of advertisers. The information gathered with the aid of conversion cookies is used to generate conversion statistics for AdWords advertisers who have opted for conversion tracking. Advertisers will see the total number of users who clicked on their ad and were redirected to a conversion tracking tag page. However, they do not receive information that personally identifies users. 


If you do not want to participate in tracking, you can object to this use by preventing the installation of cookies through a corresponding setting of your browser software (deactivation option). You will then be excluded from conversion tracking statistics. For more information and the privacy policy of Google, see:
