The initial test covered mortgage-related queries in the US. Today, we're delighted to announce that the test is being extended to cover credit card-related queries in the UK and that some major issuers have signed up to be part of the initial run.
Comparison Ads improves the ad experience on Google by letting users specify exactly what they're looking for and helping them quickly compare relevant offers side by side. There are no long forms for users to fill in, and Comparison Ads will not send advertisers any personally identifiable user information (in fact, we don't send any user information at all unless the user explicitly applies for an advertiser's offer).
It's part of our continuing effort to make ads more relevant and useful to our users and to help you, our advertisers, reach the people who are most interested in your products and services.
