Google is experimenting with its Google Adwords offerings, attempting to go beyond regular text ads with Google Email Subscription Ads, allowing companies to buy ads that automatically fill in a “Subscribe to newsletter (or whatever, I’m assuming)” slot with a given searcher’s Google email address during a search.
When asked to explain what exactly was going on, a Google representative gave me the following statement (which is basically a more official sounding version I just said):
“We’re currently running a small experiment of a new ad format that helps users sign up more easily for email subscriptions or other free newsletters. This new ad format contains a box within the ad that displays a user’s Google email address (if logged in). If a user chooses to click ‘Subscribe to newsletter’ then the email address is sent to the advertiser directly, which is clearly disclosed within the ad itself.”
