Google just announced on a live call that the variety of GDN (Google Display Network) ad image sizes has grown to over 50 sizes. Until now that’s meant that a marketing agency had to produce 50 different images to fill all the available slots. To make it easier, they’re not going to let us upload 3 core image formats and they will automatically resize as needed to fit the remainder of the ad slots.
That’s great news, it’s going to save a lot of time and cost!
They also announced many new improvements and changes to mobile ads, tracking, automated bidding, and enhanced conversion goal measurements.
