Email marketers might be very happy to know that Google is testing an AdWords format that will allow Google searchers to subscribe to their emails directly from search results pages. It’s not set in stone yet. This may or may not become widely available to all advertisers, but I’d be surprised if it didn’t open up to a wider set.
Notice the “privacy” link. If you click that, it says, “When you submit this form, your email address will be sent to the advertiser.”
The testing has been going on for a little while, but from the sound of it, it’s expanded a bit. Alexia Tsotsis at TechCrunch shared the following statement from a Google spokesperson:
“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.”
Some email marketing firms like VerticalResponse, Constant Contact and AWeber are already using the ads.
While social networking continues to rise, email and search are still the most popular online activities, and these new ads take advantage of both.
