With two clicks in the new feature, a marketer can connect her store to MailChimp and set up a campaign that shows a site visitor follow-up ads for a product left behind on your site, after the visitor had viewed it on a page or perhaps left it unbought in a shopping cart. MailChimp automatically builds ads from the stores’ best-selling products, and the marketer can tweak the ad’s headline, content or product selection. The ad is then displayed on related sites in Google’s Display Network. The company points out that the use of the ad tools has no additional charge, beyond the ads themselves. MailChimp said it plans to add other marketing channels at some point. Get the full story at MarTech and MailChimp
