We’ve seen quite a few rollouts by Google for Shopping this year. Some were big, such as an entirely new, and still-evolving Merchant Center, and others relatively small in the grand scheme of it.
As far as the display of Shopping ads themselves goes we’ve encountered Showcase formats and enhanced mobile-only styles.
Today, our team discovered yet another, and what we believe has not been seen just yet. We were only able to recreate the experience on a select few computers.
