AdWords uses a host of targeting and relevancy signals to determine the best ads for each query. However, sometimes a user's query doesn't provide enough information for us to confidently predict what they want. Take, for example, users who search for "mortgage." Do they want a new home loan or a refinance? Do they want a fixed rate or an adjustable rate loan? Comparison Ads improves the ad experience on Google.com by letting users specify exactly what they are looking for and helping them quickly compare relevant offers side by side.
With Comparison Ads, you can also target your offers at a more granular level, leading to more valuable, qualified leads. To see how it works, let's use our mortgage example. Users searching for "mortgage" on Google.com may see a promotion from Comparison Ads prompting them to select the type of loan they are looking for and to compare various rates.
If they click the promotion, users are taken to a page with more detailed sponsored results. They can choose directly from the offers listed on that page, or they can further refine their search by providing additional information like income and home value. By giving users the ability to refine their search on a number of relevant attributes, we are able to show more targeted ads and provide you with more valuable leads.
Once users find an offer that matches their specific needs, they can either call you directly or request a quote. If a user requests a quote, Google automatically anonymizes the user's phone number and sends you a unique code that you can use to contact the user. You only pay if a user calls the phone number on your offer or fills out a form to request a quote.
While Comparison Ads is still an early-stage feature, we've focused on a number of ways to enhance the user experience:
- Speed -- Comparison Ads shows targeted offers in less than a second. There are no long forms for users to fill out - Users see specific offers immediately and only need to fill in additional information if they wish to further refine their results.
- Transparency -- Comparison Ads only shows real products. There are no teaser rates, or bait and switch offers. Comparison Ads also standardizes the information presented to users, making it easy for them to sort and compare offers on a side by side basis.
- Privacy -- Comparison Ads won't send advertisers any user information, including anonymized phone numbers, unless the user explicitly requests more information about an advertiser's offer.
