Google AdWords have announced that the conversion tracking code supplied to advertisers now has an option not to be displayed on a website. Unlike Yahoo! Search Marketing and Microsoft adCenter, Google's PPC tracking code has always displayed a small line of text on the page that's displayed once an action has been submitted. This has always been there to 'comply with privacy requirements' but also helps to promote Google's involvement on an advertiser's website.

So advertisers who use this code now have the option to hide the 'Google Site Stats' line of text and link to Google's privacy page. Existing advertisers will need to revise their existing code to remove this line, if required. New advertisers, or users of the conversion tracking code, are warned by Google if they choose to hide the link, that they should inform their website users about the tracking methods being used on the site through the site's privacy policy.
