Lisa asked: Hi Google guys - Why do my ads say "Ads by Goooooogle" instead of "Ads by Google" as I've seen on some other sites?

We say: Just as we have holiday logos for our Google homepage and "Goooooooooogle" at the bottom of our search results, we thought "Ads by Goooooogle" would be a fun alternate version of "Ads by Google" for our AdSense ad units. They are both branding features we've tested, and we found that "Ads by Goooooogle" is often more memorable for users than "Ads by Google", so you may notice either label appearing beside your ads at any given time. Currently, link units and AdSense for search ads are only labeled as "Ads by Google".

So why label our ads at all? The "Ads by Google" label helps distinguish clearly between content and ads, thus providing a more positive user experience. It also distinguishes Google ads from other ads so that when users click on Google ads, they know they can trust Google to provide high quality ads targeted to their interests. This trust provides value to both publishers and advertisers.

Lastly, by clicking on an "Ads by Goooooogle" or "Ads by Google" link, users can submit feedback about the Google AdWords and Google AdSense programs. This feedback is valuable to us as we're always working to improve our feature and product offerings.
